Coatings technology for lining of tanks, piping, and vessels has rapidly advanced in recent years. Extremely tightly-crosslinked coatings are relatively impermeable, and specialty resins and pigments are formulated into linings specifically to perform in extreme environments. Why, then, is it critical to further scrutinize these lining systems by subjecting them to conceivably unrealistic temperature gradients …
