HP44 Polyaspartic Top Coat

HP44 is a user friendly, high performance polyaspartic urethane top coat that leaves a beautiful gloss finish without the orange peel texture! HP44 is a two component high solids polyaspartic clear topcoat with excellent chemical resistance, UV stability, abrasion resistance and hardness. This material is intended to be used as a high gloss topcoat over paint chips, decorative broadcasts or colored quartz broadcasts to provide an infinite array of color schemes or patterns. HP44 is designed with a user friendly 1:1 (by volume) mix ratio and has a longer working time than most polyaspartic coatings.
