2、CK STONEPECK RESISTANT TOPCOAT ESK-M99J312-A TWO PACK STONEPECK RESISTANT TOPCOAT ESK-M99J312-B 1. SCOPE The materials defined by these specifications are two pack stonepeck resistant topcoats, suitable for exterior exposure. 2. APPLICATION The materials will be pneumatic or airless applied with 2K

3、spray equipment on baked enamel on lower body areas where high stonepeck resistance is required. The materials have to be used in combination with aliphatic polyisocyanate hardener ESK-M99J313-A. The materials are as well curing by baking as by air drying. In general, ESK-M99J312-A is textured where

4、as ESK-M99J312-B is not textured and preferably used for air drying, forced air drying or infrared drying repair. 3.
