ABSTRACT:
A method and system are provided for injecting a color component into a plural component coating dispensing system. Base, cure and color components are pumped from respective containers at metered volume. The color component, which is preferably a low-viscosity automotive paint is injected into the either the base or cure stream at a point immediately prior to mixing all components in a dispensing device for dispensing the resulting colored fluid mixture onto a surface to be coated. The mixture may be dispensed by pouring or spraying onto the surface. The method and system are particularly useful for mixing and dispensing colored polyurethane or polyurea coatings, such as for spray-on truck bed liners.
