Nansulate® Accelerated Corrosion Testing

Test method: GM9540P Accelerated Corrosion Test

Why we chose this test:

The GM9540P Accelerated Corrosion Test is an advanced cyclic method originally developed by General
Motors and now the corrosion test preferred by the US Navy and many industries.

To be useful, lab corrosion tests must accurately predict the probability of corrosion in the real world,
thereby allowing more rapid selection of materials, coatings, and packaging. It is also important that a lab
test creates the same corrosion by-products and surface defects that occur in end-use. A test method,
technique, or equipment that does not provide a close match to “end use” will yield false results.

GM9540P is useful because it replicates many of the worst-case environments. The popularity of cyclic
testing comes from the improved reliability of results that can be correlated with actual use. Cyclic refers to
the repeated changes in test conditions, ideally to replicate the changing environments where the product
will be used. Rapid changes in the test condition further serve to accelerate material degradation, which
can give months or even years of information in an accelerated period of time.

The GM9540P has recently been adopted as the leading environmental corrosion test that is used
universally by the Military, Auto and Heavy Process Industries.

Our Results:
Testing was done simultaneously on a steel control (uncoated) panel and panels coated with Nansulate®.
The results show that after 1 cycle of the test, the steel control (uncoated) panel failed with 100% red rust
present, and that after 24 cycles of the test, the Nansulate coated panel passed with no red rust present.
Passing 8 cycles is considered the standard for an anticorrosion coating.

The testing was performed by Assured Testing Services, www.assuredtestingservices.com, an
independent accredited laboratory specializing in corrosion testing.
