UVA-40W Double-Tube UV Curing Lamp for Glass Adhesive

Quick answer: The UVA-40W double-tube curing lamp uses two 20W UVA tubes to provide a 365–420 nm curing source for compatible UV glass adhesives, shadowless glues, photosensitive adhesives and UV-curing resins. Reference irradiance is greater than 4 mW/cm². Confirm adhesive wavelength compatibility, working distance, exposure time, voltage and shielding before use.

Product details

What this product is used for

UVA curing of compatible UV glass adhesives, shadowless adhesives, photosensitive glues and UV-curing resins used in glass bonding and related assembly work.

Matching UVA output to the adhesive curing process

The UVA-40W lamp is designed as a compact curing source for compatible UV glass adhesives, shadowless glues, photosensitive adhesives and UV-curing resins. Two 20W UVA tubes provide a stated 365–420 nm wavelength range, while the reflective inner surface helps direct useful UVA energy toward the bonding area.

Curing time is not determined by lamp power alone. Confirm the adhesive photoinitiator range, glass transmission, bond-line thickness, working distance, exposure angle and required irradiance at the joint. Establish the production cycle through controlled curing and bond-strength checks.

Use suitable UVA shielding and eye and skin protection during setup and operation. Monitor tube output over time because curing performance may decline before a tube visibly fails.

Buyer questions

Frequently Asked Questions

What wavelength is used to cure UV glass adhesive?

Many glass-bonding UV adhesives cure in the UVA range, commonly around 365 or 405 nm. This lamp provides a stated 365–420 nm range, but the adhesive technical data must be checked for spectral compatibility.

Can UVA pass through clear glass to cure adhesive?

A portion of UVA can pass through ordinary clear glass, but transmission varies with glass composition, thickness, tint and coatings. Verify that sufficient irradiance reaches the complete bond line.

How long should UV glass adhesive be exposed?

Exposure time depends on the adhesive, irradiance at the joint, working distance, glass transmission, bond thickness and joint geometry. Establish the cycle with the adhesive instructions and a cured-bond test.

What safety protection is needed for a UVA curing lamp?

Use suitable shielding, UVA-rated eye protection and skin coverage. Avoid looking directly at the tubes or exposing unprotected skin, and follow the lamp and adhesive safety documentation.
