131-82XX Optiset® 550 Pre-Cat White Topcoat

Optiset 550 is recommended for kitchen cabinets, office and household furniture, as well as other interior wood applications.

Wood substrate should be sanded with 120, 150 or 180 grit paper prior to coating. Primers should be sanded with 280/320 grit stearated paper prior to topcoating. When recoating, the previous coat of Optiset 550 or primer must be sanded and the next coat applied within eight hours. Optiset 550 White cannot be used on metal, old oil or cellulose lacquers.

Agitate material before use. Always mix Optiset 550 while adding hardener and reducers in the recommended mixing ratios. Optiset 550 must be agitated thoroughly at all times to ensure product consistency and consistent gloss.

Apply at 3-5 mils wet on sanded or primed substrate. Further coats may be applied after complete drying followed by sanding with 280/320 grit stearated paper. Maximum film build of Optiset 550 White should not exceed 4 mils dry. Maximum film build of total coating system must not exceed 4 mils dry. The second and subsequent coats must be applied the same day as the previous coat is sanded.

Contact with metal surfaces should be avoided.

Optiset 550 White must not be polluted with oil, varnish or the like and must not be sanded with steel wool between the coats. Optiset 550 White must not be used and dried at temperatures below 18°C or relative humidity above 65%. During hardening the enamel must not be exposed to ammonia vapors. Ammonia cleaners should not be used for cleaning the finished surface. This may accelerate discoloration.
