Abstract:

Laminates in which 2-3 mil pre-formed nylon films were sandwiched between layers of nylon fabric coated with butadiene-acrylonitrile copolymer NBR. Adhesion of sulfur cured nitrile compounds to both fabric and film was strong and water-resistant provided that both fabric and film had been pre-treated with an aqueous RFL dispersion of resorcinol-formaldehyde resin and elastomer latex. Laminates consisting of thin layers of fluoroelastomer barrier films sandwiched between layers of RFL-treated nylon fabric, coated on the outside with NBR. Fluoroelastomer-nylon bonds, showed acceptable initial peel strength and excellent resistance to water. The initial adhesion of polyurethane barrier films to RFL-treated nylon was very strong, and the peel strength after water immersion was often still good. However, the polyurethane compound was noticeably deteriorated by water. Also the tear strength of nylon so coated was comparatively poor.
