  • Method of making a semi-conductive paint hose
    Patent number: 4303457
    Abstract: A composite reinforced hose for conveying paint under pressure is provided with a core tube simultaneously coextruded from two or more thermoplastic synthetic polymers which are in intimate contact with each other. The inner layer of the core tube is nylon or other chemical resistant polymer which is substantially non-conductive and the outer layer is electrically conductive. The conductive polymer layer serves as a ground for static electricity.
