QM-8599A Elastic Resin

Product Overview:

This product is a linear hydroxyl polyester resin that can be formulated with HDI-type curing agents to create elastic, tactile paints. It is primarily used for surface coating of various industrial plastics and metals. This product exhibits good weather resistance, a pleasant feel (it has a good feel even without any additives), good thickness, and excellent scratch resistance. It dries quickly, either air-drying at room temperature or oven-drying. This product requires cross-linking with HDI-type curing agents such as QM-3390.
