48 AUGUST 2018 W W W.MATERIALSPERFORMANCE.COM COATINGS & LININGS Recommendations and Conclusions In the areas with HIC concerns, apply a mechanical barrier to isolate the base metal from the service media. This barrier can be a ceramic-filled epoxy, as used in Case History 1, and application by certified c o a t i n g a pp li c a t o r s i s h i g h ly re c o m - m e n d e d . Fa st e r a pp li c a t i o n m e t h o d s should be explored to allow for better cur- ing and setting of the coating along the metal contours. Th e op erating pressure of th e unit should be strictly maintained in the normal range to avoid the risk of coating damage and subsequent base metal failure. A longer -t erm solution in areas of concern could be the application of a SS cladding.
