Product Description

Chemvar is a high quality, acid curing Reactive Amino Coating (RAC). This is a fast building product due to its high content (45% volume). Chemvar has very good light stability based on the choice of resin used in the product and the addition of a UV block additive. This conversion varnish gives a smooth, knock proof and hardwearing surface resisting influence from alcohol, water, etc.

Special recognition: when applied as specified, will meet required performance for the ANSI/KCMA A161.1 1990 9.0 Finish Test.

Uses

Chemvar is recommended for kitchen cabinets, high build office or residential furniture as well as other interior wood applications.

Surface Preparation

Before application of Chemvar, the first coat must be sanded using #280/320 grid stearated paper and free of dust and all contaminants. The topcoat must be applied within a maximum of 8 hours after sanding of the last coat applied. Chemvar must not be applied over metal, old oil finish or nitrocellulose lacquers. Stain systems used under Chemvar should be acid stable.

General Information

Catalyze and reduce material as recommended. Apply 3 to 5 wet mils on sanded surface. One extra coat can be applied following a complete cure and a sanding with a #280/320 paper. Maximum film build of the top coat should not exceed 3 mils dry. Maximum film build of the system should not exceed 4 mils dry. Chemvar must not be polluted with oil, varnish or the like and must not be sanded with steel wool between coats. Avoid all contact with metallic surfaces

To obtain complete cure, Chemvar must be applied at a temperature above 18ºC and relative humidity below 65%. When drying, this product should not be exposed to ammonia vapors. Finished surface must not be cleaned with ammonia containing products. Always use containers and equipment made of plastic or stainless steel to avoid discoloration of the material due to oxidation.

Sealers to use with 421-67XX: 390-001, 390-0060, 401-004 catalyzed, 401-028 catalyzed, 431-1219, 432-1220, 546-8003 and 546-5192.

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.
