Abstract:
    This invention relates to an impregnated oil filter substrate and to oil filters containing such impregnated substrates that require a single cure and can pass a hot oil immersion test, said filter substrate being impregnated with a water-based binder comprising a latex containing at least 20% polymerized vinyl chloride in the latex solids, the said latex being a copolymer of vinyl chloride, 30 to 60% lower alkyl acrylate, and one or more comonomers selected from acrylic acid and N-methylol acrylamide, said comonomers being used in an amount of up to 5%, based on the weight of the monomers used to make the latex; the said binder also containing 5 to 20 parts of a cross-linking resin per 100 weight parts of latex solids and 5 to 20% catalyst for the cross-linking resin based on the weight of the cross-linking resin.
