545-8001 Optiprime White Pre-Cat Primer

Optiprime is recommended for use as a primer for Optiset® White 131-83XX. It has good filling properties and hiding characteristics.

Substrate should be sanded using 120, 150 or 180 grit stearated paper prior to coating. Primers, if used, should be sanded with 280/320 grit stearated paper prior to being coated. When recoating the previous coat of Optiprime must be sanded and the next coat applied within eight hours.  Optiprime cannot be used on metal, old oil or cellulose lacquers. 

Agitate material before use.  Always mix Optiprime while adding catalyst and reducers in the recommended mixing ratios. Optiprime must be agitated thoroughly at all times to ensure product consistency.

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. The second and subsequent coats must be applied the same day as the previous coat is sanded.

Maximum film build of Optiprime should not exceed 2 – 3 mils dry.  Maximum film build of total coating system must not exceed 4 mils dry.  Contact with metal surfaces should be avoided.

Optiprime must not be polluted with oil, varnish or the like and must not be sanded with steel wool between coats.

Optiprime must not be used and dried at temperatures below 64°F or relative humidity above 65%.  During the curing process, the coating must not be exposed to ammonia vapors.  Ammonia cleaners should not be used for cleaning the finish surfaces.  This may accelerate discoloration.
