Abstract: The plural component striping spray system and method involves mixing two spray components by pumping them under pressure from heated supply systems and converting them into a fine spray within a spray gun where they mix by impingement before being blown out through a common spray tip orifice. The initiation and termination of spray from the spray tip is controlled by a shutoff needle, and the design of the mixing chamber, needle and spray tip are such that no mixed material is allowed to stay in the spray gun to cure and freeze up the gun. When the components are a resin and a catalyst, pure catalyst is the first and last material sprayed from the spray gun. The system includes a recirculation system which can become operative when the operation of the spray gun is terminated.
