LOCTITE AA 302 LC is a clear, low-viscosity UV-curable adhesive that bonds plastics, metals and glass. It is tailored for assemblies with close-fitting parts or preassembled components requiring precise adhesion.
Viscosity: low (suitable for tight fits and wicking into small gaps)
Appearance: Clear liquid before cure; clear bond after cure
Cure method: UV-light exposure for surface cure; useful for preassembled or tight-fit components
Typical applications: plastics, metals, glass substrates in tight tolerance assemblies
Primary Chemistry:
Acrylic ester (UV-curable)
LOCTITE AA 302 LC offers a one-component, light-curing solution for manufacturers needing rapid, high-quality bonding of plastic to metal, metal to glass or plastic to plastic assemblies. Its low viscosity ensures excellent flow and penetration into tight or preassembled joints, which makes it ideal for components with close tolerances or minimal gap. Upon exposure to UV light, the adhesive cures quickly, enabling fast production cycles and reducing waiting times. The cured bond is clear and strong, delivering consistent performance across plastics, metals and glass substrates. Its ease of use — no mixing, no primer, simple UV cure — helps streamline assembly and improves throughput for high-volume production.

Avoids delays associated with slow-curing adhesives or complex curing cycles.
Eliminates issues with poor bonding in tight assemblies or preassembled parts.
Reduces need for multiple adhesives when bonding different substrate types.
Prevents bond failure due to inadequate flow or poor surface contact in close-fit applications.
Supports efficient, high-quality production in sectors where appearance and adhesion reliability are essential.
Apply LOCTITE AA 302 LC to clean, dry surfaces of plastic, metal or glass components. Assemble parts as required — the low viscosity allows the adhesive to flow and fill tight gaps or fit-up tolerances. Expose assembled components to UV light to initiate cure and achieve handling strength quickly. Ensure UV light reaches all exposed bond areas. Ideal for applications in plastics-to-metal or plastic-to-glass bonding, electronic housings, transparent components, and assemblies with minimal gap.
