  • Multicomponent system for a refinish coating composition and a method for applying the same
    Patent number: 5260101
    Abstract: A multipackage system for providing a refinish coating composition and a method for applying the same onto a substrate. The method comprises separately transporting at least one component under pressure to a proportioning device which provides a controlled volumetric ratio of the components. The components of the coating composition are then mixed and coated onto the substrate at ambient temperature or, to accelerate curing, at moderate temperatures. The compositions involve new or modified existing chemistries that have a more limited pot life than conventionally formulated for commercial use.
