PVC and epoxy
I found this on another site, thought it might help.
Jim Smith Tournement Boats has been epoxying pvc for 26+ yrs. Its hard to say something doesn't work when your looking at results that were achieved in the early 80's. I spoke with John Vance of Jim Smith last a couple of years ago about this subject and he said they just scuff it and glue it.We bent some pvc tube around a flying bridge wall for use as a bolt rope track for the bottom of the enclosure. I also talked to J.R. Watson of West Systems. They have documented and quantified results of pvc epoxy bonds. From memory, just scuffing gave psi values in an acceptable IMOHO range. Interestingly they told me that by passing a torch over the surface of the pvc you will dramatically increased the bond strength. When the torch passes quickly over the pvc you can observe the gloss go away on the pvc, it happens very fast , well before any scorching. J.R. 's values indicated that this increased the bond strength to the point where the substrate let go before the bond. They will send these results to you if you ask. I for one epoxy pvc and haven't had any problems at all. PS this technique only works on sch40 , in tests in our shop we observed no visual change on sch80 and our peel tests showed no improvement over just scuffing. We can only find 3/8" tube in sch80 and have used this with no failures David www.boatsmithfl.com
