If the customer did not abrade the attach area, that would be the effect. However, (I queried an expert) I understood that epoxy would be an effective join for vinyl ester, but not the other way. True? (response from an expert) Larry , if the part is made of VE and you join or bond it with an epoxy joint compound np. because of the more aggressive covalent bond and lap shear of the epoxy. Vinylester as a joining compound has a much lower youg's modulus and subsequent lapshear so that is correct. Regards, Damian Gregory N8427 Q200 What he is saying is that one should always go equal of better in bonding two parts. polyester bonding use polyester, vinyl ester, or epoxy vinyl ester use vinyl ester or epoxy epoxy use ONLY epoxy Larry Severson Fountain Valley, CA 92708 (714) 968-9852 lar...@socal.rr.com
