  • Methods of coating fabrics with emulsions of elastomeric polymers and polyurethane dispersions
    Patent number: 6713131
    Abstract: A method for coating a substrate comprises the steps of: (I) applying a layer on the substrate of a curable composition comprising: (A) a water continuous emulsion comprising a curable elastomeric polymer having a viscosity of 0.5-1,000,000 KPa-s and a glass transition temperature up to 50° C., (B) an aqueous polyurethane dispersion, and optionally (C) a cure agent (II) exposing the layer to air for sufficient time to form a cured coating. Coated fabrics prepared accordingly are particularly useful in the construction of automobile protective airbags or other such inflatable coated textile devices.

  • Coatings for polymeric substrates
    Patent number: 6534126
    Abstract: The tack of a polymeric substrate is reduced by (i) coating a surface of the polymeric substrate with a thermosetting liquid silicone rubber composition, (ii) applying an aqueous suspension of powdered silicone rubber with a mean particle size of 0.1 to 500 micron to the coating of thermosetting liquid silicone rubber composition on the polymeric substrate, and (iii) heating the coated polymeric substrate to cure the thermosetting liquid silicone rubber composition and simultaneously adhere the powdered silicone rubber to the coating on the polymeric substrate.
