431-90XX Opticlear Pre-Cat Clear Topcoat

Opticlear is fast drying and well suited for spraying as well as coating by roller and curtain coating. The material is used for an open or semi open grain finish on all types of wood for interior use.

Wood substrate should be sanded with 120, 150 or 180 grit paper prior to staining or coating. Sealers should be sanded with 280/320 grit stearated paper prior to topcoating. The sealer should be topcoated within eight hours of sanding. When recoating, the previous coat of Opticlear must be sanded and the next coat applied within eight hours. Stain systems under acid containing coatings should be acid stable. Opticlear can not be used on metal, old oil or cellulose lacquers.

Agitate material before use. Always mix Opticlear while adding hardener and reducers in the recommended mixing ratios.

Opticlear must be agitated thoroughly at all times to ensure product consistency and consistent gloss. Apply at 3-5 mils wet on sanded substrate. Further coats may be applied after complete drying followed by sanding with 280/320 grit stearated paper. Contact with metal surfaces should be avoided.

Opticlear must not be used and dried at temperatures below 18°C or relative air humidity above 65% as the hardening may otherwise become incomplete. During hardening, the lacquer must not be exposed to ammonia vapours. Ammonia cleaners should not be used for cleaning the finished surface.

Maximum film build of Opticlear should not exceed 4 mils dry. Maximum film build of total coating system must not exceed 4 mils dry.

431-90XX can be used as a self-seal or with following sealers: 390-001, 390-0060, 431-1219, 401-004 (not catalyzed),401-028 (not catalyzed), 546-5192 and 546-8003.

Natural ambering or discoloring in the can may occur over time. Although there may be changes of color in the can as the product ages, this will have little to no effect on the product during application. Storing in locations above recommended room temperatures could accelerate ambering.
