  • Floor covering with coating composition
    Patent number: 5843576
    Abstract: Floor coverings include a wear layer made from a coat composition including a multifunctional polyurethane (meth)acrylate oligomer. The multifunctional polyurethane is made by reacting a polyisocyanate with a functionality equal or higher than 3, a polyester polyol, and a hydroxyalkyl(meth)acrylate with a number average molecular weight of about 344 to about 472. The coating composition preferably includes a reactive (meth)acrylate diluent and a photoinitiator.
    Type: Grant
    Filed: November 3, 1997
    Date of Patent: December 1, 1998
    Assignee: Armstrong World Industries, Inc.

  • Aminoplast/polyurethane wear layer for PVC support surface
    Patent number: 5643677
    Abstract: A resilient surface covering has a wear layer including a crosslinked aminoplast/polyurethane which is directly adhered to a vinyl support surface. The adhesion between the wear layer and support surface is improved by including at least 20% polyurethane by weight based on the total amount of aminoplast, polyurethane and epoxy resin in the wear layer composition, or by applying the wear layer composition to a gelled, but unfused vinyl support surface by fusing the vinyl support surface and curing the wear layer in a single step.
