UV639
Permabond UV639 is a UV-curing urethane methacrylate adhesive developed for plastics. It bonds acrylic, polycarbonate and PETG and can also join glass, metals and other compatible materials. The product offers cure on demand, high transparency, high elongation and low shrinkage, producing a clear, colorless bond where appearance is important.
UV639 is ideal for clear plastic bonding and composite repair. It supports rapid repair processes on compatible housings, panels and bonded joints where the adhesive can be exposed to the required UV light, with a clear cured appearance for visible areas.
