At first the steel is garnet blasted to create a profile on the surface. The parts are then preheated to 400 degrees, and then the first coat of 3m scotch coat 134 is applied, at approximately 4-6 mils. The part is then re-entered into the oven once again at 400 degrees to fully gel the epoxy coating. Then it is brought out and a full coat of polyester powder is electro-statically applied. Once it is fully coated it is then reentered into the oven, again at 400 degrees for approximately 30 min to fully cure the powder to the substrate. The part is then removed from the oven to cool down and it is complete.
MARINE PAINT SYSTEMS are unique point combinations designed to work as a multilayered team to protect metal in the harshest conditions. Moisture and salt associated with the marine environment "eat" metal at a prodigious rate. Unless the best coating materials are applied to the highest standards, cosmetic damage and structural erosion are sure to follow. We insist that the process start by abrasive garnet blasting to remove all foreign metal contaminants and etch a profile into the surface for the highest possible bond. Inorganic Zinc Primer is then applied to galvanically (sacrificially) protect the steel. We next apply one or more coats of Epoxy to protect the Zinc layer. We finish the system with a high gloss Polyurethane point to protect the Epoxy. Together the three components become a multi-task barrier that is exponentially better than three combined coats of any one member.
