431-1923 Chemvinyl Pre-Cat Clear Sealer

Chemvinyl is recommended for a variety of interior wood applications, including kitchen cabinets and vanities, where adhesion or moisture resistance may be a concern.

Wood substrate should be sanded with 120, 150 or 180 grit paper prior to staining or coating. Stain systems under acid containing coatings should be acid stable. AkzoNobel recommends using 825-90XX, 825-91XX Promatch® C-Mix Wiping Stains or 890-85XX Promatch Dye Stains.

Agitate material thoroughly before use. Chemvinyl must be agitated thoroughly at all times to ensure product consistency.

Apply one or two coats at 3-5 mils wet and allow 30 – 45 minutes dry at 68°F prior to sanding and applying next coating. Sand with 280/320 grit paper before top coating or re-coating and ensure next coat is applied within eight hours of sanding Chemvinyl.

Chemvinyl may be topcoated with pre-catalyzed topcoats such as 431-80XX, 431-46XX, 431-47XX and 431-70XX. Chemvinyl has a limited shelf life and should be used within six months.

Chemvinyl must not be polluted with oil, varnish or  the like and must not be sanded with steel wool between the coats. Chemvinyl must not be used nor dried at temperatures below 64°F (18°C), or relative air humidity above 65%. During hardening, the sealer must not be exposed to ammonia vapors. Ammonia cleaners should not be used for cleaning the finished surface.
