  • 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.
