  • Surface Preparation:

    Before application of Plastofix® Light RTS, substrate must be sanded using 120 or 150 grit stearated paper prior to staining or coating. Sealers, if used, should be sanded using #280/320 grid stearated paper and free of dust and all contaminants. Sealers should be topcoated within a maximum of 8 hours of being sanded. Plastofix® Light must not be applied over metal, old oil finish or nitrocellulose lacquers. Stain systems used under Plastofix® Light should be acid stable.

  • General Information:

    Catalyze and reduce material as recommended. To ensure proper sheen, the catalyzed material should be agitated at all times. Apply 3 to 5 wet mils on sanded surface. One or two extra coat can be applied following a complete cure and a sanding with a #280/320 paper. On open pored woods, the best self sealing is obtained by adding a minimum of 50% thinner to the Plastofix after catalyzing. Maximum film build of the system should not exceed 4 mils dry. Plastofix® Light 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, Plastofix® Light 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.

    421-55XX 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
