PERMABOND® UV620 is a single-part, UV-curable methacrylate ester adhesive. It cures rapidly when exposed to UV light, offering optical clarity, resistance to yellowing, and high bond strength. Its non-yellowing feature and clear finish make it ideal for applications where appearance is critical.
Key features:
Cure on demand (with UV light, 365–400 nm)
Optically clear & resistant to yellowing
Fast curing with low-power lamps
100% solids, no solvents
Excellent adhesion to metal and glass
Bonding glass and crystal (e.g., glass furniture, decorative ornaments, optical components)
Applications requiring high clarity and strong aesthetic finish
Bonding glass to metals and other transparent substrates
