Storage & Safety

Store sealed in cool, dark place at 8-25, avoid sunlight and UV light exposure. Keep container tightly closed after opening. Work in well-ventilated area, avoid skin & eye contact. Refer to MSDS for full safety guidelines.

Usage Instruction
Clean bonding surfaces to remove grease, dust and moisture.
Apply thin layer of UV glue onto one substrate.
Align and press two parts to exclude bubbles.
Irradiate bonding joint with sufficient UV-LED light for curing; curing time depends on light intensity.
Reach full bonding strength after 24 hours at room temperature.
Note: UV light must reach glue layer; shadow area cannot cure completely.

Key Selling Points

Fast UV light curing for automatic assembly lines. Single-component, no mixing required, achieves positioning within seconds under UV irradiation for mass-production efficiency.
High-clarity shadow-less bond, scratch-resistant and anti-yellowing. The cured joint is nearly invisible, maintains stable appearance for long-term service.
Multi-material compatibility. Reliable bonding for glass, crystal, PMMA, ABS, PC, resin and ceramic for electronics, crafts, new-energy and construction sectors.
No overflow & anti-cracking; sweat-resistant, insulating and weather-proof. Medium viscosity prevents glue dripping; performs well for wearable devices and photovoltaic sealing.
Solvent-free & eco-friendly. Low odor, easy operation, compatible with manual dispensing and automatic dispensing equipment.
Suitable for both new-product assembly and article repair. Restores original look for resin, ceramic, glassware and transparent plastic parts.

This is industrial-grade UV-curable adhesive for electronic component bonding. It is cosmetic-grade nail gel NOT suitable for human nail or skin contact, may cause skin irritation.
