Salt
Spray Resistance
Salt Spray fog testing evaluates coating resistance to one type of corrosive
environment. Conditions of test for salt spray resistance vary greatly. These
conditions are often specified by the end user and may require different chemical
reagents, concentrations, temperatures, and or test-cycles.
Note:
Results from any specific salt
spray condition seldom correlate
to results from other test conditions
or results from natural environmental
exposure.

Humidity Resistance
Water is often linked to coating
and adhesion failures. Pure
water, as liquid vapor can degrade the
coating or the coating-substrate
interface. Furthermore, water
as a vehicle for other chemical substances
can accelerate coating degradation.
How well a coating resists
the effects of exposure to controlled
humidity (pure water) can be
a good indicator of coating service
life. Two typical humidity-testing
techniques are the closed cabinet
in which the test panels are
exposed to 100% relative humidity @ 100
degrees F and the Cleveland
Condensing Cabinet which subjects test panels
at ambient temperatures to
condensing humidity. Failure is determined
by observation of blistering,
loss of adhesion, film undercut or significant
changes in appearance.

During
Salt Spray testing scribed or unscribed panels are are placed in a salt fog
cabinet and examined periodically for deterioration. Usually failure is determined
by observation of blistering, loss of adhesion, film undercut or significant
changes in appearance.
