How to Glue Lexan to PVC
Since Lexan, a polycarbonate polymer, and PVC are different types of plastics, special bonding agents must be used to glue the two together. The majority of plastic adhesives are meant to bond like types of plastics and therefore you need to use an adhesive that will soften and bond unlike plastics. Using the incorrect adhesive will cause a weak bond between the two materials, a failed joint will result and the contaminated joint will be compromised and render the pieces of Lexan and PVC unusable.
Things You'll Need
- Worktable
- 220-grit sandpaper
- Clean rag
- Squeeze bottle with syringe tip
- Adhesive
Instructions
-
-
1
Place the Lexan and PVC flat on top of the worktable.
-
2
Inspect the edges of the plastics to ensure that the edges you are bonding are smooth. If the edges are rough or uneven, sand the edges with 220-grit sandpaper until smooth. For applications where the flat sides of the two sheets, skip this step.

3
Wipe the surfaces of the Lexan and PVC to be glued with a clean rag to remove dust and debris from the areas.
-
4
Fill the squeeze bottle with the syringe tip with adhesive.
-
5
Place the two plastic surfaces to be bonded tightly together and apply pressure to the squeeze bottle to release adhesive into the seam.
-
6
Hold the pieces firmly in place until the glue holds the two pieces together. The hold time will vary depending on the adhesive manufacturer.
-
7
Allow the glued joint to cure for 24 hours before putting the glued Lexan and PVC to use.
