rnbraud Posted July 2, 2008 Share Posted July 2, 2008 Hello all. I have a question about bonding fiberglass to the underside of our canopy. I came across a product called Sikaflex that the RV guys use to bond there canopies to a metal frame. It is a two part product which consists of a Primer/UV (Sika 206) protector applied to the canopy, and an adhesive (Sikaflex 295UV) applied to the metal frame. This is in lieu of rivets or screws. I would like to bond fiberglass to the underside of the Cozy canopy material via a "wet layup". However, this would leave it exposed to UV radiation. So I am considering laying up the fiberglass over Sikaflex Primer 206 which has been applied to the canopy which would give me UV protection and adhesion to the canopy. My question is if anyone knows/speculates/guesses whether this will provide a good/sufficient bond between the plexi and the fiberglass once it cures? My other option is to use the canopy as a sort of mold by covering the inside with tape to form a mold release, layup the fiberglass and let it cure. Remove the cured fiberglass, remove the tape from the canopy, apply the Sikaflex primer 206 to the canopy, apply the 295 UV adhesive to the primer, then replace the cured fiberglass. As you can see the second option is way more time consuming. What are you guys thoughts? Quote Link to comment Share on other sites More sharing options...
