Resulting Properties
Contact adhesives are widely used because of their easy application, fast setting properties, and excellent adhesion to many different substrates. The contact adhesive is coated on both surfaces to be joined. After the carrier evaporates, the two surfaces are brought together under slight pressure, and the adhesive bonds to itself. Polyurethane contact adhesives can be applied similar to polychloroprene contact adhesives. A typical formulation for a solvent borne polyurethane contact adhesive is provided in the above table.
