This resin uses patented polyamide polyol technology to deliver hardness and scratch resistance that far exceed other direct-to-metal waterborne systems. Aptalon M8120 also provides outstanding hydrolysis and chemical resistance for excellent protective properties. It is designed for direct to metal applications, but can also be used over an epoxy primer. Aptalon M8120 is NMP, NEP, and APEO-free to allow for globally compliant formulations.
