Those items fail to meet requirements all the time, yet the REASONS those items fail are limited to just six causes:
a) Wrong application – not for this material, not for this temperature, not for this atmosphere
b) Out of date – date codes – these things have limited shelf life.
c) Bad mix – precise measurements are required
d) Bad surface preparation – mechanical or chemical
e) Exceeded Working time
f) Bad application technique – spray, dip, brush
If anyone has ever seen a paint, coating, adhesive or potting compound fail for any OTHER reason, please post here.
