With a few exceptions like Nylon and Mylar, Epoxies in general will form poor bonds to thermoplastics like ABS, PVC, Polyethylene, Acrylic, ect. A structural strength bond should not be counted on when bonding to these materials. However, a reasonably good bond can be achieved by using our Gelmagic Structural Adhesive and flame treating the surface prior to bonding.
Flame treat by using a propane torch and quickly waving the flambe back and forth over the surface to be bonded. Do this for 30-45 seconds keeping the flame 6-8 inches from the surface, bond withing 1 hour.
