What can be used in states that will not allow the use of MEK for IOZ testing per ASTM D4752?


Is the MEK rub test a conclusive test to check the cure of IOZ coatings?


What causes bubbling or cratering of epoxy intermediate coat when applied over epoxy zinc-rich primer?


On guardrails on a marine wharf, grating panels consisting of mild steel bars about 1/8-inch by 1-inch on a 2-inch-square grid were painted with a three-coat zinc/epoxy/urethane system. Inspectors are finding numerous pinholes in the finish coat along the inside corners of the grating where the 1-inch-thick bars meet at a 90-degree angle. These pinholes were not noticed in the zinc or epoxy coats, but the final coat's visual inspection is more detailed. What is the likely cause of the pinholing, and what could be done to prevent it on future applications? Also, what should the disposition of the parts with pinholes be, as in, repair, accept as is, reblast and recoat, or an alternative?


What is the recommended coating system and procedure for repairing deteriorated inorganic zinc/epoxy/polyurethane 3-coat systems? Does the repair system or procedure vary with the degree of deterioration and if so, how?


What can be done to prevent rust bleed in crevices when applying a zinc/epoxy/urethane system?


What are the significant performance differences between an inorganic zinc primer (ethyl silicate) and an organic zinc primer (epoxy), given the same application and exposure conditions?


Zinc metalizing has been applied to concrete surfaces to provide cathodic protection to rebar in the concrete. What are the problems, if any, with applying zinc metalizing to concrete, and what is the best approach to addressing them?


What is the effect of using a lower-metallic-content zinc-rich epoxy on the life of a paint system?


What can be done to prevent rust bleed in crevices when applying a zinc/epoxy/urethane system?
