421-72XX Plastofix® Light Post-Cat Clear Topcoat

Plastofix is an all round coating equally suited for application with roller and curtain coating as well as conventional spraying equipment.

Substrate must be sanded using 120 or 150 grit stearated paper prior to staining or coating. Sealers, if used, should be sanded prior to being coated with 240, 280 or 320 grit stearated paper. Sealers should be topcoated within eight hours of being sanded. Plastofix cannot be used on metal, old oil or cellulose lacquers. Stain systems used under acid catalyzed systems should be acid stable.

Catalyze and reduce the material as recommended. Plastofix is applied in one to three coats on all kinds of wood meant for indoor use. On open pored woods, the best self sealing is obtained by adding a minimum of 50 percent thinner to the Plastofix after catalyzing. Thorough sanding between the coats is a must for good adhesion. The second coat must be applied within 8 hours of the board being sanded.
Contact with metal surfaces should be avoided once the Plastofix has been catalyzed. To ensure proper sheen, the catalyzed material should be agitated at all times.
Plastofix must be thoroughly stirred while adding hardener and thinner in the recommended mixing ratio. Total recommended film build of Plastofix and sealer should not exceed 4 mils dry. To obtain a complete cure, the system should be applied at an ambient temperature above 18ºC and a relative humidity below 65%. When drying, this product is not to be exposed to ammonia vapors. Finished surfaces must not be cleaned with ammonia containing products.

421-72XX can be used as a self seal or with following sealers: 390-001, 390-0060, 401-004 catalyzed, 401-028 catalyzed, 431-1219, 432-1220, 546-5192 and 546-8003.
