Ref: AES/ENV/HSF/4500/0913-­‐001 SUMMARY This documents reports the finding of a Hot Salt Fog Exposure test on Enviropeel Corrosion Inhibiting Sprayable Thermoplastic (CIST), conducted by A&E Systems Technical Department in accordance to ASTM B117 standards. ASTM B117 ASTM B117 is a standardized test for coatings on steel substrates using a controlled hot-­‐salt mist environment. The test is designed to evaluate the long-­‐term performance of protective coatings by subjecting samples to a super-­‐enhanced corrosion-­‐inducing environment over extended periods of time and is widely regarded as providing a consistent indication of long-­‐term performance in the most severe ‘real-­‐world’ conditions. A standard nickel-­‐plated carbon-­‐steel bolt would be specified at 1000 hours (42 days) of testing – with a life expectancy of several years. For current CIST testing, a continuous period of 4500 hours (188 days) has been chosen following earlier 3000 hour testing. ENVIROPEEL CIST Although CIST utilizes a radically different methodology to that of an ordinary passive coating, performance under standard ASTM B117 conditions is a reliable indicator of long-­‐term performance under extreme conditions. CIST is a recyclable non-­‐toxic zero-­‐VOC thermoplastic, developed to protect bolted systems such as flanges and valves. The material contains continuously active corrosion-­‐inhibitors and is spray applied as a two-­‐layer coating. TESTING Test flanges were coated with one layer of epoxy zinc primer. Zinc-­‐plated carbon steel bolts were used to join the flanges. All samples were placed in a controlled hot salt fog cabinet at 35oC for 4500 hours. All but one of the test flanges were coated according to standard procedures with CIST. The remaining flange without Enviropeel coating was also placed inside the cabinet as a control. After 4500 salt-­‐spray test conditions for 4500 hours, the control flange was found to be severely corroded with heavy pitting and surface corrosion. No Enviropeel CIST coated samples showed any sign of deterioration within the encapsulated areas.

Ref: AES/ENV/HSF/4500/0913-­‐001 Hot Salt Fog Test & Methodology The test was conducted in accordance to ASTM B117-­‐11 Standard Practice for Operating Salt Spray (Fog) Apparatus. The practice was designed to provide a controlled corrosive environment for metal or coated metal samples. The standard covers the apparatus, procedure and condition to create and maintain the salt spray environment. The salt spray cabinet used for this test s shown in Figure 1.

Comparison against the control flange

Ref: AES/ENV/HSF/4500/0913-­‐001 CONCLUSION After 4,500 hours of exposure the control flange has significantly deteriorated with high levels of corrosion whereas the Enviropeel coated sample is completely unaffected – preserved in its original condition. Bolt threads, nuts and all encapsulated surfaces are seen to be corrosion-­‐free. The test has proven Enviropeel’s effectiveness in eliminating corrosion with the protected substrate showing no signs of deterioration and inhibitor levels in the Enviropeel after 4500 hours remaining satisfactory. A&E Systems will continue the test until 7500 hours and ultimately 10000 hours with the same configuration and some minor improvements. This test provides further confirmation of Enviropeel’s impeccable performance record, from successful 3000 hours pre-­‐release testing in 1997, to the following 16 years of successful applications in some of the worlds’s most challenging environments.
