PERMABOND UV670

Permabond UV670 is a single-part flexible UV-curable adhesive for glass-to-metal, metal and metalized-plastic assemblies. The methacrylate ester adhesive has a viscosity of 2,000-3,000 cP at 25 deg C and cures across 365-400 nm. Typical fixture is 2 seconds under a 100 mW/cm2 LED source; cure time depends on lamp output, distance and substrate transmission. After cure, typical steel-to-glass tensile strength is 6-10 N/mm2, tensile strength is 12 N/mm2 and elongation exceeds 80%. UV670 is used for flexible glass-to-metal and metalized-plastic joints.

Key features

• Flexible glass-to-metal UV bonding: The cured adhesive combines >80% elongation with steel-to-glass tensile strength of 6-10 N/mm2.
• Fast 2-second UV fixture: Typical fixture is 2 seconds under a 100 mW/cm2 LED source; actual cure time depends on the UV setup and substrate transmission.
• 2,000-3,000 cP viscosity: The single-part adhesive has a typical viscosity of 2,000-3,000 cP at 25 deg C.

Applications

Metal-to-glass bonding; bonding metal and metalized plastics; flexible glass-to-metal assemblies.
