The process is called plastics welding. Methylene chloride is the primary ingredient in a number of commercial plastics welding compounds available at most hardware stores.
Things You Will Need
-
Put on your respirator and rubber gloves. Open all windows in the room or relocate to an open-air location to prevent against the buildup of toxic fumes.
-
Lightly sand the locations where you want to glue the pieces of Lexan together. The locations should be smooth to the touch.
-
Apply the methylene chloride solution to the Lexan according to the instructions on the package. Most solvents designed for plastics welding come in containers with eye-droppers for purposes of application. The solvent is thin like water and takes some practice to use well, so consider experimenting on some scrap pieces first.
-
Clamp the two pieces together and wait 24 hours for the bond to achieve its maximum strength.
