Neoprene rubber contact bond adhesive

Shoe adhesives. CR adhesives are used for the permanent attachment of shoe soles. For difficult-to-bond sole materials (plasticized PVC, EVA foaming soles, thermoplastic rubber, SBR) graft polymer solutions of Neoprene AD-G combined with a polyisocyanate provide a good adhesion. Another major area for CR contact adhesives is the manufacture of leather goods, particularly leather shoe sole bonding and belt lamination. 

Adhesives. Contact adhesives are blends of rubber, phenolic resin, and additives supplied in solvent or aqueous dispersion form they are typically applied to both surfaces to be joined (98). Evaporation of the solvent leaves an adhesive film that forms a strong, peel-resistant bond. Contact adhesives are used widely in the furniture and construction industries and also in the automotive and footwear industries. The phenolic resins promote adhesion and act as tackifiers, usually at a concentration of 20-40%. In solvent-based contact adhesives, neoprene is preferred, whereas nitrile is used in specialty applications. The type and grade of phenolic resin selected control tack time, bond strength, and durability. 

A common finishing item for various types of flooring are vinyl and rubber cove base trims. Generally, resin-type adhesives are used for these cove bases, extruded in parallel strips approximately 1 " to 2" apart along the back of cove base. Alternatively, cove base can be installed very efficiently with neoprene contact cements. The cove base is first put into position without any adhesive, and a light pencil mark made along the top edge of the cove onto the wall surface. The neoprene contact cement is then brushed in the space below the pencil mark as well as on the back side of the vinyl or rubber cove base, the solvent is allowed to evaporate, then cove is pressed into position for immediate bond.
