Patent

CA 2037953

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 consists of blend polymer of NBR 40 - 80%, EPDM 20-60%, and SBR 0 - 35% by weight respectively. Solventless urethane coating material is applied on each primer layer and a urethane coat is formed. Flocking is provided only on flocked layer area. Said urethane coat is cured during the vulcanizing process for a glass run substrate, and in this way a urethane slip layer and a flocking layer can be formed.
