Abstract: A kind of high build epoxy aluminum powder paint as a universal primer for ships has been developed, which showed excellent corrosion resistance and good compatibility with shop primer and ancillary cathodic protection. A series of experiments have been conducted on the selection of types and dosage of aluminum powder and curing agent. And the formulation was finalized by balancing the mechanical and corrosion resistant performance of paint film and cost, etc. The performance tests results including cathodic disbonding resistance, compatibility with shop primer and oil immersion met the technical specification of standards.

Key words: aluminum powder paint, high build, epoxy paint, corrosion resistance
