Questions and answers in the adhesives and sealants industry.
Question: I need to adhere a small acrylic hinge to two pieces of glass. So far, I have tried what I believe to be everything on the market, including epoxy, silicone and UV adhesives, and many others. What do you suggest?
Answer: Bonding to many plastics, including acrylics, often requires some type of surface preparation. Abrading the surface followed by a degreaser, such as methyl alcohol, would greatly influence the bond. An epoxy adhesive should work for this application. You might try changing to a different epoxy to see if it provides better adhesion. However, you might also try using an acrylic adhesive to obtain a good bond.
