The OH terminated polyester chains are DMPA® Dimethylolpropionic acid initiated polycaprolactone. The combination of both hydroxyl and carboxyl functionality produces unique benefits and versatility. The acid group promotes water dispersability of the resin after neutralisation with a base or can improve adhesion to difficult substrates. This product has a melting point (DSC) of 59.3°C, a non-volatile content of 99% wt. min., a viscosity @ 60°C of 800-1000cP, and an acid equivalent weight of 935-1122g/eqv. Since no DMPA is required to formulate water dispersible pre-polymers, NMP may be reduced or eliminated from the formulations. Pre-polymers formulated with DICAP® products have very good solubility in monomers for hybrid applications and in acetone for solvent-free PUDs. Depending on the molecular weight of the DICAP® polyol and the formulating technique, hard films can be formulated for durable coatings or soft urethane polymers can be formulated for coating textiles and leathers. DICAP® products can be used in compliance with 21CFR 175.105 for indirect contact with food. view less |
