New Primer Binds TPV To Steel Wire

Conveyor and transmission belts, hoses, hoisting strips, and drive cables of PP-based thermoplastic vulcanizate (TPV) reinforced with steel wire and cord can be made more economically with new primer and adhesive tie-layer technology from Advanced Elastomer Systems (AES), Akron, Ohio, and NV Bekaert SA of Belgium.

Conveyor and transmission belts, hoses, hoisting strips, and drive cables of PP-based thermoplastic vulcanizate (TPV) reinforced with steel wire and cord can be made more economically with new primer and adhesive tie-layer technology from Advanced Elastomer Systems (AES), Akron, Ohio, and NV Bekaert SA of Belgium. AES produces Santoprene TPV and Bekaert makes steel wire products. The primer and tie layer are said to greatly improve mechanical properties of the reinforced TPV and also to reduce costs because fabricators no longer have to go through a lengthy process of metal treatment before applying the TPV. One key to the technology is said to be good coating penetration of the primer. Bekaert (represented here by Bekaert Corp., Research Triangle Park, N.C.) can supply custom-made steel wire and cord coated with the new primer or with the primer and tie-layer adhesive resin.
