ABSTRACT:
A production method for a glass run of EPDM material with a urethane slip layer and/or a flocked layer on its glass sliding area, whereby a primer layer for a urethane slip layer or a flocked layer can be co-extruded together with a glass run substrate of EPDM material. The primer layer is a polymer blend of NBR 40-80%, EPDM 20-60%, and SBR 0-35% by weight, respectively. Solventless urethane coating material is applied on each primer layer to form a urethane coat. Flocking is provided only on flocked layer area. The urethane coat is cured during vulcanization of the glass run substrate, and in this way a urethane slip layer and a flocking layer can be formed.
