Abstract
A nonskid coating for a carpet or mat is provided by placing a patterned polyurethane on the carpet, the polyurethane being permanently tacky. The method includes the steps of forming a precoat coating of one reactive formulation and forming a secondary coating of a second reactive formulation. The one reactive formulation is a polyurethane for holding face yarns in the carpet backing, and the second reactive formulation includes a diamine to render the formulation thixotropic and a tackifier for rendering the cured polyurethane tacky.
