Loctite AA 3494 Light Cure Adhesive

High-Performance Glass Bonding with LOCTITE AA 3494

LOCTITE AA 3494 is a commercial-grade, clear light-cure acrylic adhesive engineered for high-speed production environments. Designed for maximum efficacy in bonding, potting, and sealing, this modified acrylic cures in seconds upon exposure to UV or visible light (365nm). As a leading industrial supplier, we keep LOCTITE AA 3494 in stock for rapid dispatch, offering competitive bulk pricing for manufacturing facilities and assembly lines.

This medium-viscosity, transparent liquid prevents bond failure caused by structural impact, prolonged humidity, or water immersion. It serves as an industry standard for assembling rough surface decorative glass, molded glass tableware, and automotive lighting components where optical clarity and environmental resiliency are critical.

Why Procurement Managers Trust LOCTITE 3494

• High-Speed Production Cure: Achieves fixture strength in under 10 seconds (with sufficient UV intensity), eliminating assembly line bottlenecks.
• Exceptional Environmental Resiliency: Exhibits superior resistance to prolonged condensing humidity, boiling water, and motor oil exposure.
• Optical Clarity: Cures transparently (Refractive Index 1.5), maintaining aesthetic integrity for cosmetically critical assemblies.
• Versatile Compatibility: Forms robust, leak-proof structural bonds on glass, steel, aluminum, polycarbonate, ABS, and PVC.

Application & Handling Guidelines

For optimal adhesion, ensure all substrates are completely clean and free from grease before application. Because LOCTITE AA 3494 is highly light-sensitive, keep exposure to daylight and ambient artificial lighting to an absolute minimum during storage and handling.

• Dispense the liquid adhesive using [Link to: Black Feedline Applicators] to protect the uncured product from premature light exposure in the line.
• Expose the assembled components to a high-intensity [Link to: 365nm UV Curing Lamp] to initiate the rapid cure cycle.
• Any excess, uncured adhesive squeeze-out can be easily wiped away with an organic solvent such as [Link to: Industrial Grade Acetone].

Frequently Asked Questions (FAQ)

What materials can LOCTITE AA 3494 bond? LOCTITE AA 3494 is specifically formulated to bond glass to itself, as well as to steel, aluminum, G-10 epoxyglass, polycarbonate, PVC, and ABS. It is widely used for potting and sealing automotive lighting and decorative glass.

What is the required curing method for LOCTITE 3494? This adhesive requires exposure to ultraviolet (UV) or visible light at a 365nm wavelength. The cure rate and ultimate depth of cure depend on the light intensity, the gap distance, and the light transmittance of the substrates the light must pass through.

Is LOCTITE AA 3494 water-resistant? Yes. Once fully cured, it exhibits excellent environmental resistance, maintaining high bond strength even after prolonged exposure to condensing humidity, boiling water (up to 2 hours), and continuous water immersion at 49 °C.

Can this adhesive be used in oxygen-rich systems? No. LOCTITE AA 3494 is strictly not recommended for use in pure oxygen or oxygen-rich systems, and it must never be selected as a sealant for chlorine or other strong oxidizing materials.
