MPC-165 is a 100% solid, super fast curing two component epoxy coating designed for controlling moisture vapor emissions on new or deteriorated concrete floors. This coating is recommended to be applied as a primer in areas of high humidity or on wet concrete. When applied at a thickness of 18 mils, it exceeds ASTM F3010 product requirements for vapor permeance. This coating will withstand moisture vapor emission rates up to 25lbs./24hrs./1000 ft 2 when applied properly.
