Amine curing agents are quite important in meeting the formulation strength and performance requirements of epoxy coated floor systems. These curing agents will provide additional adhesion, impact strength, and protection from numerous chemicals by bonding with the epoxy resin at the mid coat layer. Together with primer and top coat, the mid coating serves as mechanical and cohesive structural bond. The middle coat can be designed to achieve certain requirements such as increased thickness for heavy-duty applications and enhanced chemical resistance for industrial applications with the type and amount of amine compounds used.
