Polyurethane coating compositions comprising isocyanurate compositions from bis(isocyanatomethyl) cyclohexane and tertiary amine catalysts
Abstract:
The present invention provides high solids, two-component polyurethane compositions comprising, as one component, polyisocyanate compositions having one or more isocyanurate made from bis(isocyanatomethyl)-cyclohexane, as a second component, one or more high solids polyol, and in either component, one or more tertiary amine catalyst. Optionally, the compositions further comprise one or more zinc amine catalyst. The compositions provide coatings, which exhibit an excellent balance of pot life and dry to touch or tack free time, as well as early rain resistance and hardness, while enabling a lower volatile organic content (VOC) of the compositions for comparable performance.
