POLYCOR® 998 BASE WHITE
Polycor® 998 Base White series enamels are formulated to be used as topcoats on fiberglass laminates. Enamels are very similar to gel coats except they cure tack-free on the open surface. Enamels are used to seal and hide a substrate. Normally they are used as interior finishes and yield a pigmented surface. Polycor® 998 series enamels were primarily developed for marine applications; however, they can be used in any FRP application where high performance characteristics are desired. Polycor® 998 series enamels produce a hard, tough, durable coating that reduces maintenance on composites parts. Polycor® 998 series enamels cure to a flat finish. Standard enamels should not be used for water immersion service due to potential water spotting and water blistering. Contact a sales representative for a recommendation if water immersion is required. Polycor® 998 series enamels meet the EPA national emission standards for hazardous air pollutants NESHAP for both marine manufacturing and reinforced composites production. Polycor® 998 series enamels contain wax. The wax is essential to yielding a tack-free surface in the top coating application. The wax also helps to suppress the volatile organic compounds emitted in to the air. Together the low VOC or hap content and wax results in:reduced monomer emissionsless odorsmoother sprayed film less orange peel less overspray due to the wax, Polycor® 998 series enamels should not be used as an in-mold coating where they will be backed by laminate or other materials. Delamination could occur. Enamels require only the addition of the proper amount of the appropriate methyl ethyl ketone peroxide to cure. These enamels are available in White or any of the Colors listed in the standard gel coat color card. Special Colors are available upon request.
