LOCTITE® 4310LC is a transparent, low viscosity light cure cyanoacrylate adhesive that also cures via humidity. It provides rapid fixture in under five seconds when exposed to UV or visible light, without needing accelerators. Its dual cure system is ideal for bonding metals, plastics and rubbers, offering minimal blooming and a tack free surface.
Viscosity: approximately 180 mPa·s
Shear strength on grit blasted mild steel: ~20 N/mm² (2950 psi)
Fixture time with light cure: under 5 seconds (visible or UV)
Gap fill: up to 0.15 mm
Elongation at break: about 7.3 %
Operating temperature range: –40 °C to +100 °C ()
Specific gravity: ~1.06 at 25 °C
Primary Chemistry:
Ethyl cyanoacrylate with photo initiator
LOCTITE® 4310LC bonds close fitting parts with precision. Its light cure capability enables flash curing of exposed areas, while humidity curing secures shadowed or blind joints. This dual cure method ensures a uniform cure without risking bloom. The adhesive is biocompatible (ISO 10993 compliant) and ideal for medical device assembly, electronics, and general industry. It fluoresces under UV for quality inspection, maintains rigidity when cured, and resists environmental stress.

Use LOCTITE® 4310LC where fast fixturing is essential—for example in medical devices, electronic assemblies or high value components. Apply adhesive to substrates, flash cure exposed surfaces with UV or visible light and allow humidity to complete cure in shadowed areas. Fluorescence helps confirm coverage. No mixing needed. Suitable for bonding metal to plastic, metal to rubber, and other hybrid materials.
