Corrosion protection – Reduce fretting corrosion
Corrosion protection – SuperCORR A helps to reduce fretting corrosion on gas turbine connectors.
LP Gas Turbines are used throughout the world by extraction industries and manufacturing plants in remote and hostile locations for essential power production. Dusty and wet environments in deserts, mines, grinding mills, pulp and paper mills and on land or sea drilling rigs for gas and oil production. Turbines powering aircraft services while stationary connect and disconnect many times a day in extreme conditions. These applications and locations test connector sealing continuously allowing dust or water to penetrate. This with the flexing of the connecting cables allows sufficient movement between the metal surfaces of the connecting pins to produce fretting corrosion which reduces, interrupts or produces failures in supply. Regular maintenance of electrical connectors is essential to be certain of uninterrupted supply.
RUB TEST RESULTS
Super CORR A is an aerosol lubricant containing corrosion preventive compounds.
A manufacturer of connectors tested Super CORR A to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the connectors at all. The connector looked and tested as good as new. This test was run under clean conditions in a laboratory but demonstrates the effectiveness Super CORR A.
As it meets Mil MIL-DTL-87177B (revised MIL-L-87177A) specifications it is used by the U.S. Air Force to protect the intricate workings of the F-16 and F-15 fighter jets and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for avionics and electrical switches and connectors and close mechanical application, especially where flights are in salt fog or high humidity.
Containing extremely long-lasting, proprietary anti-corrosive inhibitors Super CORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electromigration problems. The super thin non-flammable lubricant film is only 7 microns (0.007mm) thick and is formulated without sulphates, chlorides or halogens to meet the RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.
Very fast drying, environmentally acceptable solvents are used as carriers and propellants which will not affect most plastics, substrates, metals or other materials used in connector manufacture. The aerosols are supplied with probes which allow access to pins and connector tubes where the low surface tension repels water, dirt dust and metal particles from blind holes and surfaces to produce thoroughly clean holes and surfaces before a second application applies the lubricant film. Reconnection to the supply with cleaned sections of the connector ensures reliable operation even in the most testing of environments. One can of Super CORR A allows this essential task to be carried out in any conditions quickly, easily and securely.

Methylene chloride based vapour degreasing solvent with a unique blend of surfactants giving it superior cleaning quality
EnSolv® CC-A is a methylene chloride based vapour degreasing solvent with a unique blend of surfactants giving it superior cleaning quality
EnSolv® CC-A responds to the need for high performance vapour degreasing solvents for critical cleaning in general engineering, aerospace, medical optical and electrical industries. It builds on 30 years of experience supplying the EnSolv® range of powerful and reliable vapour degreasing solvents to industries worldwide
EnSolv® CC-A removes cutting oils, lubricants, lapping compounds grinding pastes and water based cutting oils or fluids. This complex synergistic blend utilises environmentally compliant solvents combined with selected surfactants to remove oils and lubricants to the highest standards for critical cleaning applications and releases and suspends inorganic solids and soils such as fingerprints, polishing compounds and grinding paste from finely finished and highly polished surfaces such as stainless steel and plated parts, optical lenses and components for medical appliances.
SAFE FOR USERS AND THE ENVIRONMENT
Environmentally friendly cleaning all the constituents of EnSolv® CC-A are environment friendly and compliant with REACH. This proprietary blend has no global warming potential (GWP) no ozone depletion potential (ODP) does not produce ozone at ground level and is biodegradable. EnSolv® CC-A addresses many of the problems faced by the engineering industries in meeting environmental legislation.
Easily biodegradable all the components of the EnSolv® CC-A formulation are widely used in industry but only trace elements have been detected in atmosphere and they are not detectable in rivers, oceans or ground water. This is attributed to its high volatility and biodegradability by naturally occurring organisms. Released into the atmosphere it is photochemically degraded reacting with naturally occurring hydroxyl radicals producing only carbon dioxide and hydrogen chloride simple chemicals already present in the environment.
No depletion of the ozone layer and no global warming. EnSolv® CC-A has an atmospheric lifetime of only 6 months and does not accumulate in the atmosphere so is not transported into the ozone layer. The most urgent challenge for the future is reduction of gases which produce global warming. The solvents and any breakdown products of this formulation do not produce greenhouse gases and the reduced energy needs of vapour degreasing with EnSolv® CC-A lower the power station production of CO2 for equivalent work throughput.
No ground level ozone production – authorities are becoming increasingly concerned at ground level pollution causing increased asthma and bronchial diseases much of it due to photochemical production of Ozone affecting children and adults. EnSolv® CC-A has a minimal impact on ozone formation with an extremely low photochemical ozone creation potential (POCP).
Reduced solvent emissions (VOCs). Improving air quality is a high priority for the European Union and governments worldwide with the elimination of VOCs as a high priority. The use of EnSolv® CC-A with its excellent environmental profile assists the engineering industry to meet increasingly severe environmental legislation on solvent emissions allowing continued use of vapour degreasing with all the production benefits it offers.

Eliminate bad smells using unique concentrated water based cleaning system
Aquus® CL-One is the ALL purpose concentrated cleaning system based on an innovative formulation of surfactants which also controls odours and will eliminate bad smells at source.
The unique combination of properties exhibited by Aquus CL-One offers excellent emulsion-breaking capability in addition to its unusual combination of properties that makes it so attractive for a wide range of industrial applications including an unusual application which is discussed below in more detail, utilising these properties to control odours and eliminate bad smells at source.
CONTROL ODOUR BY ELIMINATING UNPLEASANT SMELLS AT SOURCE
Aquus CL-One eliminates odour problems caused by bacteria and other organisms. No fragrance or other masking agents are used, the odour is very effectively eliminated at source. Conventional masking agents use fragrances or enzymes which act slowly and are less effective and more expensive than the Aquus CL-One alternative which uses a totally different approach to these problems.
MANY APPLICATIONS FOR ODOUR CONTROL
Odour control is needed where cleaning is performed in food preparation, processing equipment and containers, sewage treatment plants and in other waste-water facilities.
VOLATILE ORGANIC COMPOUNDS
Aquus CL-One breaks down the organic compounds responsible for the release of the volatile organic compounds (VOCs) producing the unpleasant smells associated with some commercial and industrial processes and systems.
Aquus CL-One eliminates the ability for bacteria to produce the odour producing VOCs by disrupting the integrity of the cell walls. Odour producing microorganisms have cell walls made up of organic materials including lipids (fats). The alkalinity and surface-active ingredients of the Aquus formula breaks down the cell walls of the organism which protect the inner workings. Once compromised the bacteria can no longer absorb nutrients and eliminate waste. This kills the organism which then cannot generate the VOCs which produce the smells.
ADVANTAGES OVER OTHER METHODS
Aquus CL-One has considerable advantages over the toxic, fragrance or enzyme based alternative odour control products which only mask the smells. Enzyme based formulas need regular maintenance to keep the enzymes active and work slowly. Masking agents are usually ineffective and expensive.
Aquus CL-One eliminates completely the odours and smells associated with these organic materials including bacteria and other organisms simply and effectively.
ENGINEERING WASTEWATER TREATMENT SYSTEMS
Aquus CL-One is extremely effective in separating oil, water, and solids in drains, conveyor traps and sumps on automatic honing, turning and grinding machines when using water-based lubricant and cooling liquids.
Emulsions are broken allowing cleaned metal dust, shavings and dirt to precipitate to the bottom, the solution of Aquus CL-One and water retains the active cleaner in the middle layer, oil and grease float to the top. The efficiency of oil/water separators in plant waste treatment systems are significantly increased while the disposal of toxic waste is greatly reduced.
FARMING AND AGRICULTURE
Farming and agriculture require reliable water-based cleaners for the innumerable cleaning applications needed particularly where animal husbandry is involved. Scrupulous cleaning of surfaces on rails, floors and walls is essential for the health of the animals. The unique bacterial destruction abilities described earlier is very effective in odour control in many farming applications
Aquus CL-One is the concentrated water activated cleaner which is used at different dilutions to meet the requirements of the many applications and challenges met in farming and agriculture. Aquus CL-One which is completely biodegradable within 30/40 days, is not toxic and not considered a hazard which is particularly important in sensitive environmental sites and situations. Safe for use with any application equipment such as high or low-pressure washers, spray washers or dip tanks it can be used with mops, brooms etc by operators without needing personal protective clothing.
The unique combination of oleophilic and hydrophilic properties encourage sedimentation of solids from liquids in wastewater separation tanks and as the cleaner solution can be recycled and reused until biodegradability reduces its effectiveness it is very economical in use. As an example, in normal use a one litre bottle is mixed with 40 litres of water to activate the cleaning solution which in turn can be recycled many times.
HOSPITALS AND HEALTHCARE
Cleaning of soiled and contaminated surfaces in hospitals, nursing homes and other medical facilities is essential to control bacterial contamination. Aquus CL-One cleaner can be used for all cleaning applications which reduces time and costs by removing the need for multiple cleaning products usually needed to deal with the challenges presented by the wide range of soils, oils, blood, body liquids and other contaminants which need to be removed.
Aquus CL-One is safe for the environment and users, contains no solvents and is biodegradable within 30 days. With only one product for all cleaning applications incorrect selection or dangerous uses can be avoided.

A Real Fire Suppression System Problem and Your Electronics and Computer Systems
HFC-227ea is replacing Halon 1301 as the gaseous fire suppression agent for data processing and electronic equipment.
However when activated in a fire situation HFC-227ea will decompose to produce Hydrogen Fluoride. This is a real and ongoing concern. Why? Because Hydrogen Fluoride causes major corrosion problems for electronics and connectors. You may save your equipment but for how long?
In 2004 the Institute of Research and Construction in Canada published a study on HFC-227ea (C3F7H) paper, Thermal decomposition products from fire suppression with HFC-227ea in an electronic facility 1. That study was followed by Corrosion of Electronic Components by Hydrogen Fluoride (HF)2 in 2008 by the Fire Research Program of the National Research Council of Canada. Both studies were published in the Journal of Fire Protection Engineering. These two in depth studies address and prove the very definite concern of Hydrogen Fluoride (HF) corrosion after a gaseous HFC-227ea fire suppression system is used in computer and other electronic environments.
The first published study by the National Research Council of Canada (NRC) in 2004 showed that HFC-227ea, a gaseous fire suppressant, a replacement for Halon 1301, produced at least 5 to 10 times more HF than Halon 1301 under similar fire conditions, however, there was no information available on the amount of thermal decomposition products generated during fire suppression with halocarbon agents in an electronic facility.
The Corrosion of Electronic Components by Hydrogen Fluoride (HF) paper published in 2008 describes in detail the HF corrosion and provides the test results showing the corrosion damage due to HF. While HFC-227ea is a very good fire suppression system, the HFC-227ea thermal decomposition byproduct, Hydrogen Fluoride, would cause serious and expensive short and long term extensive corrosion damage by the condensed Hydrofluoric acid. Hydrogen Fluoride corrosion severely affects computers, servers, switching circuits, and other electronics, connectors and electromechanical devices.
To prevent corrosion caused by Hydrogen Fluoride, as well as other chemicals, acids, salts, and water which can be deposited during the activation of fire suppression systems or rapid humidity changes, all the electrical and electronic hardware, boards and connectors should be sprayed or coated with SuperCORR A, an ultra-thin film lubricant and corrosion preventive compound that is non-hardening and will not crack. SuperCORR A is a water displacing non-flammable compound that will not interfere with any type of electronics or avionics and prevents corrosion.
While a fire suppression system utilizing HFE-227ea will put out the fire, SuperCORR A will protect and prevent damage to the electronics or avionics caused by exposure to the Hydrogen Fluoride produced as a byproduct during the fire. SuperCORR A Mil-L-87177, is also effective in preventing damaging corrosion by atmospheric gases such as Sulfur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia (NH3), and Chlorine based gases (CL2) in Class III mixed gas tests and fresh or salt water systems.

An ounce of protection is worth a pound of cure
“An ounce of prevention is worth a pound of cure.”
Benjamin Franklin said that in 1736 and it is as true today as it was then.
One of the most important opportunities for savings today is the prevention of failures caused by corrosion. Corrosion leading to the repair of or the complete re-placement of failed parts or components, a pound of cure, which is preventable, equates to increased production costs and a decrease in the bottom line profits.
SuperCORR A is the ounce of prevention that will save your company money; man hour costs and parts in the re-pair or replacement of equipment that failed because of corrosion issues that are easily preventable. Whether it’s an electrical connection that failed because of corrosion which caused a cooling pump to shut down that caused a bearing to overheat and burn out that brought an entire production line to a halt or it’s the floor of an airliner that was so corroded that the aircraft was grounded for extensive repairs, corrosion is a serious and a very expensive problem. A problem that is preventable.
An ultra thin-film lubricant with corrosion preventative compounds that displaces water, SuperCORR A has been extensively tested on metals and electronics and has shown extremely good results in preventing corrosion.
The question to ask yourself is: What is the cost of NOT using SuperCORR A to prevent corrosion?
If you were able to say we are saving £100 a day by using SuperCORR A by not having a failure caused by corrosion would that be a good thing? How about saving a £1000 a day? A saving that would directly influence the bottom line.
You have essentially two choices:
1). Being proactive about corrosion and doing something simple and very cost effective to prevent it,
2). Do nothing and take your chances that the cause and the associated costs of the next lost production time are not directly related to a preventable corrosion problem.
Being proactive about corrosion and doing something that is cost effective and protects the bottom line is nothing but a positive. Remember the cost of lost productivity is directly related to lost profits.

See how SuperCORR A can save money and time changing light bulbs
Question – How many engineers does it take to change a lightbulb?
Answer – One,
but they’ll spend three hours checking it for alignment and leaks.
There are thousands of jokes on this theme but anywhere, factories, offices, warehouses, supermarkets, sports stadiums, railway stations, ocean liners, road lighting and other applications where thousands of light fittings are installed it can be a major maintenance expense rather than a joke.
SuperCORR A is a corrosion preventative dry lubricant aerosol which rejects water and protects the bulb socket and fitting and prevents sticking. This makes bulb changing easy and quick.

SuperCorr A defeats increasing gold prices for connector manufacture
Thinner plating caused problems with increased corrosion on USB connectors as gold coating thickness decreased with escalating gold prices.
A major company in the U.S. found that by using SuperCORR A it was able to prevent galling corrosion due to vibration on printed circuit leads and connectors.
They found that because of the advances in gold plating technology the plating thickness was being reduced over the base substrate metal of the connectors. The thickness of the gold plating became thinner and thinner over time. This thinner coating saved a lot of money as gold was and is becoming increasingly expensive. However the resulting reduced thickness of gold plating also resulted in failures caused by corrosion. Minute irregularities in the surface of the connectors base metal caused irregular or uneven wear of the connector causing the “high spots” on the connector to wear through the gold plating.
Using SuperCORR A prevented or delayed the corrosion and subsequent failures. However it must be recognized that
SuperCORR A is a lubricant with corrosion preventive compounds, and as is the case with all “lubricants” they will be worn off over time. Having said that, the Company also had SuperCORR A tested to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the USB connectors at all. In fact they commented that the USB connector looked as good as new.

Corrosion Control
Corrosion is a serious problem for industry and governments worldwide. Most people associate corrosion with rust, which only happens in things made of ferrous metals such as steel girders, ships, iron pipes, steel reinforcement rods, and steel tanks and is the reason metals deteriorate and fail.
Ferrous and non-ferrous metals corrode on contact with both fresh and salt water as well as water vapor. They will also corrode when they come in contact with chemicals, liquid acids as well as acidic vapors, salts and bases, and bacteria.
Read our article “Corrosion Control Solutions – A Solution To A Costly Problem” for more information about the enormity of the costs involved in failing to prevent corrosion.
