Abstract:
A continuous process for coating ePTFE with polymer wherein a first coating of fluoropolymer-containing liquid medium is formed on a moving elongate substrate, elongate ePTFE is contacted with the coated substrate to form an inchoate composite structure, and a final coating of fluoropolymer-containing liquid medium is formed on the inchoate composite structure.
