PERMABOND UV6231

Permabond UV6231 is a single-part optically clear UV-curable adhesive for glass, crystal and glass-to-metal assemblies. It cures across 365-400 nm and reaches typical fixture in 2 seconds under a 100 mW/cm2 LED source; cure time varies with lamp output, distance and substrate transmission. After cure, typical steel-to-glass tensile strength is 10 N/mm2 and elongation exceeds 120%. After 500 hours at 70 deg C and 90% relative humidity, steel-to-glass tensile strength is 6-7 N/mm2. The adhesive is used in bathroom-type and outdoor assemblies requiring moisture, humidity and weathering resistance.

Key features

• Optically clear glass and crystal bonding: The cured adhesive remains clear and resists yellowing for glass and crystal assemblies.
• 2-second LED fixture: Typical fixture is 2 seconds under a 100 mW/cm2 LED source; actual cure time depends on the UV setup and substrate transmission.
• 500-hour humidity-conditioned strength: Steel-to-glass tensile strength is 6-7 N/mm2 after 500 hours at 70 deg C and 90% relative humidity.

Applications

Glass and crystal bonding; glass-to-metal bonding; bathroom-type assemblies; outdoor assemblies.
