Adhesion on Galvanized Steel
We just took on a new job for some parts that are hot-dipped galvanized and we are having big problems with adhesion failure.
Q. We have been coating a lot of different substrates for some time now including hot-dipped galvanized (HDG) steel with no major problems. We just took on a new job for some parts that are HDG and we are having big problems with adhesion failure. We clean the parts in our five-stage washer and apply the coating. The parts look good but often fail the adhesion test.

Powder coating is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe because of its lack of volatile organic compounds.
I am an engineer on a large yacht build project and urgently need information and advice on choosing a finish for the aluminum deck plates in the engine room.
