Product Description

Optiprime is a one-component, high solids, Pre-Catalyzed Reactive Amino Coating (RAC) used as a primer.

Optiprime is recommended for use as a primer for Optiset 131-82XX or E.S. Lacquer White 131-51XX. It has good filling properties and hiding characteristics.

This coating may be catalyzed to further enhance its durability. Contact your coating supplier for a recommendation.

Surface Preparation

Substrate should be sanded using 120, 150 or 180 grit stearated paper prior to coating. Primers, if used, should be sanded prior to being coated with 280/320 grit stearated paper. 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.

General Information

Agitate material before use. Always mix Optiprime while adding hardener 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 the coats. Optiprime 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.

Topcoats to use over 545-8016: 131-50XX, 131-51XX, 131-82XX, 117-30XX, 117-32XX and 484-6XX

THE CUSTOMER IS RESPONSIBLE FOR FOLLOWING THE RECOMMENDED APPLICATION PROCEDURES. FAILURE TO ADHERE TO THE RECOMMENDATIONS GIVEN IN THIS DATA SHEET WILL LIKELY RESULT IN UNSATISFACTORY FILM APPEARANCE OR FILM FAILURE. THE COMPLETE COATING SYSTEM SHOULD BE CHECKED FOR REQUIRED PROPERTIES PRIOR TO THE START-UP OF PRODUCTION.

---

Dry times are greatly affected by film build, porosity of substrate, air movement as well as heat and humidity. Temperatures are based on actual board temperature. This may vary depending on length of time for boards to reach these temperatures. Minimum curing temperatures of 64°F/18°C must be maintained throughout the curing cycle to achieve the film integrity as stated in product features.
