Jesmonite® AC730 Flex Metal Gel Coat is a rapid setting acrylic polymer modified cement-based composite that incorporates real metal powder to achieve a range of metallic finishes. It is designed to be brush applied into molds with both AC730 and AC830 composites being used as backing materials with suitable glass reinforcements. It is a shrinkage-compensated material of low permeability and is durable in all conditions of external weathering. The compound is alkali-free and as such is free from the efflorescence associated with ordinary Portland cement-based systems. It is supplied as two components, a water-based acrylic liquid, and a blended Base.
