Polyurethane-63 is a complex polymer formed by first reacting dimethylolpropionic acid (DMPA) and isophorone diisocyanate (IPDI) with a polyester diol made with Adipic Acid, isophthalic acid, and Hexanediol. The resulting prepolymer is then neutralized with triethylamine and finally, chain-extended with ethylenediamine.
