Introducing the New UVLED82 – UV LED Adhesive from MG Chemicals
Introducing the MG Chemicals UVLED82 – UV LED Adhesive
The MG Chemicals UVLED82 is a UV LED adhesive formulated to cure under both broadband UV and LED light sources at 365, 385, 395, and 405nm — the wavelengths used by modern LED UV curing systems. Cure time is 5–30 seconds depending on light source intensity and adhesive thickness, significantly faster than traditional UV adhesives that require longer exposure or mercury lamp systems. The UVLED82 provides 20–25 MPa tensile strength, low viscosity for easy dispensing and precise application, and broad substrate compatibility including glass, plastic, metal, and ceramics. It is designed for precision electronics applications including edge bonding, camera modules, fibre optic connectors, PCB encapsulation, and glob top. Available at MTE Solutions in 30ml and 300ml sizes.

Frequently Asked Questions
What is the difference between UV LED adhesives and traditional UV adhesives?
Traditional UV adhesives cure under broadband UV light from mercury vapor lamps, which emit across a wide spectrum including shorter UV wavelengths (254nm, 313nm) as well as longer wavelengths. Mercury lamps require warm-up time, generate significant heat, and have limited lamp life. UV LED adhesives like the UVLED82 are formulated to cure specifically under LED UV sources at defined wavelengths (365, 385, 395, 405nm). LED UV systems turn on instantly, generate less heat, have longer service life, and are more energy-efficient. The UVLED82 is also compatible with broadband sources, providing flexibility if your facility uses both lamp types.
What curing equipment do I need for the UVLED82?
The UVLED82 cures under any UV LED source emitting at 365, 385, 395, or 405nm — the most common wavelengths for industrial LED UV curing systems. It also cures under broadband UV mercury lamp systems. Cure time (5–30 seconds) depends on light source intensity (irradiance in mW/cm²) and adhesive layer thickness. Higher irradiance = faster cure. Consult the MG Chemicals UVLED82 technical data sheet for specific cure energy requirements (mJ/cm²) for your application.
What is the difference between the 30ml and 300ml sizes?
The 30ml size is suited for low-volume applications, prototyping, qualification testing, and applications where shelf life after opening is a concern — smaller volume reduces waste if the adhesive is not used frequently. The 300ml size is the production format for higher-volume applications where the adhesive is used regularly. UV adhesives have a defined shelf life and should be stored per the manufacturer’s recommendations (typically refrigerated, away from light) to maximize usable life.
Can the UVLED82 be used for shadow cure areas where UV light cannot reach?
UV-cure-only adhesives cannot cure in shadow areas — any adhesive not directly exposed to UV light will remain uncured. If your application has shadow areas (e.g., under components, inside joints), a dual-cure adhesive (UV + heat or UV + moisture) would be required. The UVLED82 is a UV/LED cure adhesive — verify with the MG Chemicals technical data sheet whether it offers any secondary cure mechanism for shadow areas, or contact MTE Solutions for guidance on selecting the right adhesive for your specific joint geometry.
