UV645 Plastic Bonding UV-Curable Adhesive, Clear, 1 Liter Bottle
Permabond® UV645 is a single-part, fast-curing, high-viscosity UV curable adhesive designed specifically for bonding plastics. This material has excellent adhesion to a variety of plastics including polycarbonate as well as metals and glass. Permabond UV645 has very high shear strength, elongation, and impact resistance making it ideal for applications that require substrates with different coefficients of thermal expansion. Permabond UV645 has good depth of curing capabilities which make it suitable for use as a sealant.

Physical Properties of Uncured Adhesive
- Chemical composition: Methacrylate ester
- Appearance: Colourless, clear
- Viscosity @ 25°C:
- 20 rpm: 8,000-10,000 mPa.s (cP)
- 2.5 rpm: 30,000-60,000 mPa.s (cP)
- Specific gravity: 1.1
Typical Curing Properties
- Typical fixture time (acrylic)*
- Low power 4mW/cm2 battery lamp: 10secs
- LED 100mW/cm2 lamp: 4 secs
- UV light guide 30W/cm2: 2 secs
- Cure wavelength 365 - 420 nm**
*The cure time depends on the power of the UV lamp, its spectral output, the distance between the lamp and the components, and the transmission characteristics of the substrates.
**LED UV lamps have a narrow range of spectral output. It is important to check suitability with Permabond to match the LED lamp's peak wavelength with that of the adhesive's photoinitiator to ensure optimal adhesive cure.
