Loxeal 30-20 UV-Curable Adhesive 50ml
Loxeal 30-20 is a fast-curing, high-strength UV adhesive purpose-made for glass and crystal bonding. Under a suitable UV lamp it sets in as little as 6–10 seconds, and its water-clear finish with over 98% light transmittance makes joints all but invisible — the go-to choice for decorative tableware, household and furnishing accessories, giftware and fine crystal work.
Why choose Loxeal 30-20?
- Cures in seconds under UV light (365 nm) — parts are handled almost immediately
- Exceptional optical clarity: clear, colourless, non-yellowing joints
- High bond strength on glass-to-glass and glass-to-metal assemblies
- Bridges bond lines from 0.03 mm up to 1.5 mm
- Convenient one-part product — no mixing, cures only where the light reaches
Typical applications
Bonding glass and crystal in decorative tableware, homewares, furnishing accessories, bonbonnières and gift articles; ideal for precious crystal pieces where the joint must stay invisible.
How to use
- Ensure both parts are clean and completely dry.
- Apply a small amount of adhesive to one surface and bring the parts together.
- At least one part must be UV-transparent — align the assembly before exposure.
- Cure with a UV source emitting between 365 nm and 420 nm (around 100 mW/cm² recommended); exposure of 6–10 seconds is typically sufficient.
- Allow slightly longer exposure for larger gaps or tinted substrates.
Cure times
Typical fixture under a suitable UV lamp is 6–10 seconds. Actual cure time depends on lamp intensity, distance from the light source, bond-line gap and how much UV passes through the substrate.

Chemical resistance
Cured Loxeal 30-20 shows excellent long-term resistance to alcohol and refrigerant gases and good resistance to gasoline. Sustained exposure to high humidity (90% RH at +40°C) reduces bond performance, so it is best suited to dry indoor service.
Important notes
- At least one bonded part must transmit UV light for the adhesive to cure.
- Cure speed drops with tinted or UV-filtering glass — extend exposure accordingly.
- Not recommended for permanently damp or wet environments.
- Store in a cool, dry place at no more than +25°C, away from daylight; do not return used product to the bottle.
Safety
Consult the Safety Data Sheet (SDS) before use and avoid looking directly at UV curing lamps without eye protection.
