Modern high performance paint systems are so durable that when exposed to natural weathering they may show only slight signs of deterioration. This means that new coatings being marketed have limited track records. Which creates an increased reliance on accelerated laboratory testing to evaluate performance.
Overview of coatings for a cyclic-temperature environment. Test method, including a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Factors to be considered for coating selection in the cyclic-temperature environment are discussed.c
