ABSTRACT:
Two-part reactive polymeric paints are prepared and applied from an integral dispensing system. The reactive components are held in two separate containers and are maintained separate from one another by a fusible plug. To use the dispenser, heat is applied to the fusible plug to melt the plug and permit the container contents to mix together. Differential pressure between the containers causes the components to mix and begin to react; a net positive pressure with respect to the ambient atmosphere permits the mixed components to be applied as a spray. In an alternative embodiment, a flexible, external spray feed tube permits easier paint application than by conventional paint spray cans.
