Resulting Properties
Several contact adhesive formulations for flooring construction are given in the table above. 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. The surfaces can also be heated to speed drying time and to increase tack. A high degree of handling strength occurs immediately, and the joint strength increases further with time. Because of its immediate bond strength neoprene contact adhesives are generally only used with small flooring sections such as tile.
