***ALL Polyglass 320 Resins NOW USE Universal Catalyst and All-Purpose Reducer/Thinner!!*** Conventional topcoats were developed in the 1950's--the same time as TV dinners!

Polyglass 320 Resin is an eco-friendly topcoat that meets the federal guidelines for low VOC's. It offers all the benefits of earlier coatings but with low VOCs. This also means the odor is greatly reduced.

    For the average size bathtub (35 square foot surface), mix 10 oz. of Poly Glass 320 resin with 5 oz. of Universal Catalyst (by volume). Thin with 5 oz. of All Purpose Reducer to spray apply. Spray 1 light tack coat followed by 2 wet coats. Pause between coats to inspect the work. Allow the coating to “tack’ before applying the next coat. At 75F and 50% humidity, Poly Glass 320 Resin will dry to touch in approximately eight minutes. Remove masking paper and apply caulk in 30-45 minutes after the last coat is applied.

    Notes and Precautions:
    Refer to the MSDS sheet before use. The NAPCO PolyGlass 320 Resin should be shaken constantly for 20-40 seconds before use. For a 35-square foot tub, mix 10-oz of PolyGlass Resin, with 5 oz. of Universal Catalyst and 5 oz. of All Purpose Reducer.
    All components should be stored indoors between 50-90 F. Shelf-life in unopened containers is one year from the date of manufacture. The catalyst is particularly sensitive to high humidity, so the catalyst container must be kept closed at all times when not in use. The viscosity of the resin will more than double at 50F vs. 75F (perhaps requiring more reducer for proper spray, which further lengthens the recoat tack times as well as slowing down the cure). If the components are stored at high temperatures, (90F and above), the viscosity of the base will noticeably be lowered, and the solvents in the mixed paint will evaporate more rapidly, causing too fast a “dry” and may result in a lower gloss and powdery finish. The shorter pot-life at high temperatures could lead to drastically shortened working time and could even gel in the paint pot.
