HIGH PERFORMANCE MARINE POWDER COATING
At first the steel is garnet blasted to create a surface profile. The parts are then preheated to 400 degrees, and then the first coat of 3m scotch coat 134 or Zinc rich epoxy 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.
POWDER COATING
POWDER COATING begins with all parts being garnet blasted to remove old paint, surface contaminants and oxidation. The surface is also etched by abrasive blasting to provide a profile so the dry powdered resin can bond as it gels. The parts are first preheated to 400º and then the powder is applied. The POWDER COATING to metal attachment becomes tenacious as the gel cures "rock" hard in the oven. POWDER COATING is unquestionably the most preferred coating we apply for general use. The cosmetics are superior to sprayed liquid paints and the longevity surpasses all but the most specialized marine paints. The part is then removed from the oven to cool down and it is complete.
HIGH PERFORMANCE MARINE EXTERIOR COATINGS FOR STEEL (Paint)
SANDBLASTING PROVIDES THE IDEAL SURFACE FOR HIGH PERFORMANCE COATINGS. SANDBLASTING REMOVES OLD PAINT, CORROSION, MIL-SCALE AND OTHER CONTAMINANTS THAT MAY ADVERSELY AFFECT ADHESION OF THE NEW COATINGS. EQUALLY IMPORTANT, THE PROCESS PROVIDES A SURFACE ETCH FOR THE LIQUID COATING TO FILL AND MECHANICALLY ATTACH ITSELF TO.
INORGANIC ZINC PRIMER, AS WELL AS ZINC METAL SPRAY, IS FOLLOWED BY 1 TO 2 COATS OF AN INTERMEDIATE COAT OF EPOXY AND TOP COATING OF POLYURETHANE, IS CONSIDERED THE BEST SYSTEM AVAILABLE TODAY. THESE THREE COATINGS WORK AS A “TEAM”. THE COMBINATIONS WILL PROTECT AND ENHANCE THE APPEARANCE BETTER THAN ANY 3 APPLICATIONS OF ANY SINGLE COATING.
ZINC COATINGS ARE A SACRIFICIAL COATING. IT “GIVES ITSELF UP” (SIMILAR TO GALVANIZING) TO PROTECT THE SUBSTRATE. IT PREVENTS CORROSIVE UNDERCUTTING OF THE TOPCOATS WHEN A BREAK OR CHIP OCCURS IN THE SURFACE OF THE PAINT.
THE EPOXY INTERMEDIATE COAT IS USED TO PROTECT THE ZINC AND PROVIDEAN ADHESIVE BASE FOR THE TOP COAT. EPOXY IS SUPERIOR GENERAL PURPOSE ANTI-CORROSIVE. IT CANNOT PROVIDE A GLOSSY FINISH AND EPOXY WILL BREAK DOWN UNDER PROLONGED EXPOSURE TO THE SUN. A TOPCOAT IS REQUIRED.
THE POLYURETHANE TOP COATING IS SIMPLY THE PREMIER GLOSSY LONG-LIVED FINISH FOR YOUR METAL PARTS AND STRUCTURES. IT PROTECTS THE EPOXY FROM SUNLIGHT AND PROVIDES A HIGHLY AESTHETIC APPEARANCE. VIRTUALLY ALL COMMERCIAL AIRCRAFT, CUSTOM YACHTS, AND “LONG-HAUL” TRUCKS USE POLYURETHANE FOR THE FINAL COAT.
COST IS ALWAYS AN IMPORTANT CONSIDERATION. WE BELIEVE THAT THE COST OF COATING SERVICES SHOULD BE FACTORED OVER THE LIFE OF THE COATING. WE CAN DEMONSTRATE THAT SERVICE LIFE COSTS ARE LOWER WHEN SANDBLASTED AND HIGH PERFORMANCE COATINGS ARE USED TO FINISH YOUR METAL PARTS.
