Physical Properties of Uncured Adhesive

Chemical composition: Methacrylate ester
Appearance: Colourless, clear
Viscosity @ 25°C: 2,200-2,900 mPa.s (cP)
Specific gravity: 1.0

Typical Curing Properties

Typical fixture time*:
- Low power 4mW/cm² battery lamp: 5 secs
- 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 to match the LED lamp's peak wavelength with that of the adhesive's photoinitiator to ensure optimal adhesive cure.

Typical Performance of Cured Adhesive

Tensile strength (ASTM D-2095-69) steel to glass*: 9-10 N/mm² (1300 psi - 1450 psi)
Tensile strength (ISO37): 16 N/mm² (2300 psi)
Refractive index (cured): >1.490
Elongation (ISO37): 80%
Hardness (ISO868): 65-75 Shore D
Dielectric strength: 12 KV/mm
Dielectric constant 1MHz@25°C: 4
Water absorption (ISO62) 2 hours in boiling water:<4%

*Strength results will vary depending on the level of surface preparation and gap.
