NP321HWS: High Wear Urethane
NP321HWS consists of a two component polyester/aliphatic polyurethane floor sealer and heat treated corundum form crystalline tabular alumina. When combined, they product a slip resistant coating that is extremely wear resistant. In addition, this product exhibits excellent chemical resistance, flexibility, weathering and UV stability.
RECOMMENDED FOR: Recommended for any area where a slip resistant high wear coating is required such as auto service centers, warehouses, laboratories, aircraft hangers, cafeterias, indoor or outdoor service and chemical exposure areas. The clear HWS system, which incorporates a non-clear tabular alumina, is not intended for use over colored products and may lose some of the clear characteristics associated with the unmodified NP321 clear.
