Why Polycarbonate Polyols?
Higher Performance At Competitive Pricing
Polycarbonate polyols offer higher performance than polyester and acrylic polyols in urethane formulations. The use of polycarbonate in bulletproof windows is well known. Less known is that branched polycarbonate polyols formulated into urethane coatings offer seemingly contradictory characteristics of toughness and chemical resistance, or hardness and toughness. They also offer better water resistance as well as adhesion than polyester or acrylic polyols. Attributes of polycarbonate, polyester and acrylic polyols in urethane coatings is shown below on a scal of 1-5, where 5 is the highest.
