MG Chemicals UVLED82-300ML UV LED Adhesive, 300ml
MG Chemicals UVLED82-300ML UV LED Adhesive, 300ml
UVLED82 is a 1-part, low-viscosity, UV light adhesive formulated for rapid cure under suitable UV exposure conditions. It is specially formulated to cure using both broadband and LED light sources such as 365, 385, 395, and 405nm, making it ideal for edge bonding chips and other circuit components when high throughput is needed. The low viscosity coupled with depth of cure enables encapsulation of parts up to a thickness of 5mm (1/5"), and the adhesive contains a secondary cure mechanism that allows for curing in shadowed areas.
Sold in a 300ml cartridge.

Frequently Asked Questions
What light sources cure UVLED82?
UVLED82 is formulated to cure using both broadband and LED light sources such as 365, 385, 395, and 405nm, and cures rapidly under suitable UV exposure conditions.
Can UVLED82 cure in shadowed areas?
Yes. The adhesive contains a secondary moisture cure mechanism that allows for curing in shadowed areas where UV light cannot reach.
How thick can UVLED82 be applied?
The low viscosity coupled with depth of cure enables encapsulation of parts up to a thickness of 5mm (1/5").
What materials does UVLED82 bond?
UVLED82 bonds strongly to metal, glass, and many plastics. Its low viscosity also allows it to easily wet out horizontal surfaces.
Is UVLED82 suitable for electronics assembly?
Yes. It is ideal for edge bonding chips and other circuit components when high throughput is needed, and is also used for read/write heads on disk drives, camera modules, fibre optic connectors, couplers and isolators, photovoltaic cells, PCB encapsulation, and glob top.
Is UVLED82 a one-part adhesive?
Yes. UVLED82 is a 1-part UV light adhesive, so there is no mixing required before use.

Curing and Handling
The October 17, 2024 TDS gives these exposure options: broadband 320–500 nm at 5 W/cm² and 25 J/cm² for 5 seconds; 365 nm LED at 2 W/cm² and 50 J/cm² for 25 seconds; 395 nm LED at 2 W/cm² and 50 J/cm² for 25 seconds; or 405 nm LED at 5 W/cm² and 50 J/cm² for 10 seconds. Validate the selected process for the actual assembly rather than treating these as universal cure times. Although the grade supports 385 nm, this TDS does not give a separate 385 nm exposure schedule.
The TDS identifies secondary moisture cure for shadowed areas but does not give a shadow-cure time. Do not assume UV exposure times also describe the moisture-cure process. Prepare surfaces free of oils, dust and residues. Follow the cartridge instructions for dispensing, stopping flow, cleaning the nozzle and recapping. Store at 4–40°C in a dry area away from sunlight, and recap firmly when not in use.
How do the 30 mL and 300 mL packages compare?
Both contain UVLED82 in cartridges. The 30 mL package contains 32.1 g net adhesive; the 300 mL package contains 321 g. Choose according to consumption and the dispensing setup. These net material weights are not shipping weights.
Does the secondary cure mean shadowed areas cure in seconds?
No. The TDS lists moisture cure as a secondary mechanism but does not specify its duration. Confirm shadow-cure conditions with MG Chemicals and validate the process.
