PERMABOND UV630
Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide
Main features
- Low-Viscosity Plastic Bonding
- Fast 365 to 420 nm Cure
- High-Elongation Cured Bond
Product Description
Permabond UV630 is a single-part, low-viscosity methacrylate adhesive for fast UV bonding of plastics, including polycarbonate. The clear liquid has a typical viscosity of 250 mPa s at 25 deg C and cures across 365 to 420 nm. Depending on lamp output and substrate transmission, fixture time on acrylic ranges from 10 seconds with a 4 mW/cm^2 battery lamp to 2 seconds with a 300 mW/cm^2 light guide. The cured adhesive combines typical tensile strength of 14 N/mm^2 with 110% elongation and high shear and impact resistance for assemblies using substrates with different coefficients of thermal expansion.
Key features
- Low-Viscosity Plastic Bonding: A 250 mPa s viscosity supports controlled application to plastic joints.
- Fast 365 to 420 nm Cure: Fixtures on acrylic in 2 to 10 seconds under the stated lamp conditions.
- High-Elongation Cured Bond: Provides 110% typical elongation with high shear and impact resistance.
Applications
Applications include plastic bonding, polycarbonate assembly, and joints that combine substrates with different coefficients of thermal expansion.
