Permabond UV6231 is a single part, fast curing, UV curable adhesive. Its excellent optical clarity and resistance to yellowing make it ideal for bonding glass and crystal for a high quality finish. It has excellent resistance to moisture and humidity making it ideal for bathroom-type applications (such as bathroom scales, shower doors etc.) and also outdoor applications where good resistance to weathering is essential.

Features & Benefits

  • Cure on demand
  • Optically clear
  • Excellent environmental resistance
  • Fast curing with low-power lamps
  • 100% solids, no solvents
  • Excellent adhesion to metal and glass

Physical Properties of Uncured Adhesive

Chemical composition Methacrylate ester
Appearance Colourless, clear
Viscosity @ 25°C 20 rpm: 5,000-8,000 mPa.s (cP)
Specific gravity 1.1

Typical Curing Properties

Typical Fixture Time* Low power 4mW/cm² battery lamp: 5secs
LED 100mW/cm² lamp: 2 secs
UV light guide 30W/cm²: 1 sec
Cure wavelength 365-400 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 in order to match the LED lamp’s peak wavelength with that of the adhesive’s photoinitiator to ensure optimal adhesive cure
