Product Description

Variset Primer is a one-component, high solids, pre-catalyzed Reactive Amino Coating (RAC). This product is formulated using the same chemistry as Varicure^® with easy sand and great build. Variset Primer comes in a ready to use format, there is no need for reduction. This pigmented pre-catalyzed RAC has very low odor during the curing process. Variset Primer is also HAPs solvent free. 

Uses

Variset Primer is recommended for use as a primer for Variset and Variset Plus. It has good filling properties and hiding characteristics.

Surface Preparation

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

General Information

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

Apply at 3 – 5 mils wet sanded substrate.  Further coats may be applied after complete drying followed by sanding with 280/320 grit stearated paper. 

Maximum film build of Variset Primer 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.

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

Variset Primer 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.

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.
