Abstract
Non-slip laminatable materials are provided by coating a polymer sheet backing with mineral particles adhered to the backing by a radiation curable adhesive.
Claims8
A non-slip article comprising a polymeric backing of material selected from the group consisting of polyvinyl chloride, polyethylene, polyurethane, polyester, polypropylene, polyamide, polysulfide, polystyrene, polyvinyl acetate, polybutadiene, styrene-butadiene, acrylonitrile-butadiene, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer and vinylidene chloride, said polymeric backing having from about 10 to 25 lbs./ream of a mineral particulate material bonded thereto by from about 4 to about 15 lbs./ream of radiation cured polyurethane binder material, said polyurethane binder material comprising a blended mixture of at least one grade of polyester urethane acrylate resin and a combination of ethoxyethoxyethyl acrylate and N-vinyl-2-pyrrolidone monomer, and wherein the linear tensile strength of the non-slip article is at least as great as the linear tensile strength of said polymeric backing, and wherein the elongation capability (before tearing occurs), of said non-slip article, is at least 25%, of that of said polymeric backing, and said elongation capability (before tearing occurs) of said non-slip article is also at least 125%, in any given direction, of the unelongated dimension in that same direction;
- the backer material and the resin bonding material being selected such that the non-slip is thermoformable without delamiantion or decomposition of the components.
