Hi mattman,
Thanks for the info. I spent a little time looking over the sites you recommended and will spend more. Mostly what I'm looking for is a laminating epoxy (or other resin) that will adhere to ABS (the top surface of the sidewall strip) because the same resin will also have to be applied to the top layer of composite during lay-up. Maybe Loctite or Devcon has an actual laminating resin listed of their site and I just haven't found it yet.
Over the last few months, I've found bonding adhesives that will bond ABS quite well, but haven't found a laminating resin that does. One possible alternative/option that I came across during a patent search is to apply an approiate bond adhesive to the ABS surface during lay-up, allow it to set up a bit (but not completely cure), then finish the lay-up as usual with epoxy laminating resin. When the lay-up is heat cured, the bonding adhesive and the laminating resin chemically fuse together as a combination polymer, creating a strong bond.
As I indicated before, because a lot of ski manufactures are using ABS, it's probably quite a simple process to get it to bond well. Those in the know are probably reading this thread and chuckling at our efforts to figure it out.
