Converge® HMA-1 by Aether Industries is a polycarbonate polyol. It is a blend optimized for viscosity and hydroxyl number. Carbon dioxide accounts for approximately 30% of the polyol mass. The aliphatic polycarbonate backbone delivers unique high performance to polyurethanes in terms of both strength and environmental resistance. In coatings, it delivers UV resistance and high hardness. It can also improve abrasion resistance. It has excellent compatibility with polyester polyols and isocyanates. Compatibility with polyether polyols is low to moderate; it is recommended that ether-based systems are cured shortly after polyol blending. Converge® HMA-1 is compatible with standard chain extenders, surfactants, and catalysts. Suitable for coatings.
