Permabond

UV648 Non-Drip Plastic Bonding UV-Curable Adhesive, Clear

In Stock

Permabond® UV648 is a UV-curing adhesive developed for use on plastics. It has superb adhesion to acrylic and contains a long-wavelength photoinitiator to allow it to cure through UV-stabilised plastics. This adhesive can also be used to bond glass, metals, and other materials. UV648 cures to give a colourless bond so is ideal for applications where aesthetic appearance is vitally important.

Physical Properties of Uncured Adhesive

Chemical composition: Urethane methacrylate
Appearance: Colourless, clear
Viscosity @ 25°C:
- 20rpm: 20,000-40,000 mPa.s (cP)
- 2.5rpm: 120,000-180,000 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.
