LOCTITE® AA 3504 LC is a clear, medium-viscosity UV and visible-light curing acrylic adhesive designed for bonding plastics, metals and glass. It provides fast fixture, strong adhesion and a transparent finish for high-precision assemblies.
LOCTITE® AA 3504 LC is formulated for high performance bonding in applications requiring clarity, durability and fast cure. The adhesive polymerises rapidly when exposed to UV or visible light, enabling efficient production cycles with minimal waiting time. Its medium viscosity supports accurate and controlled dispensing, helping prevent excess adhesive flow in narrow, complex or vertical geometries. Once cured, LOCTITE® AA 3504 LC provides a tough and reliable bond across plastic, metal and glass substrates.
The LC designation indicates a low-chlorine formulation, making this grade suitable for electronics, optical assemblies and sensitive devices where contamination control is essential. This adhesive is ideal for clear housings, medical components, sensor assemblies, plastic parts and precision devices where both structural integrity and appearance matter.
Eliminates slow or inconsistent bond strength associated with multi-component adhesives.
Prevents adhesive spreading into unwanted areas during assembly.
Removes the need for separate bonding systems when joining mixed substrates.
Ensures aesthetic clarity in visible or transparent product designs.
Supports low-contamination manufacturing environments by providing a clean LC formulation.
Primary Chemistry:
Acrylic ester, light cure

Supports low-contamination manufacturing environments by providing a clean LC formulation.
Apply LOCTITE® AA 3504 LC to clean, dry bonding surfaces. Assemble components and expose the joint to UV or visible light to achieve rapid fixture and handling strength. Its medium viscosity supports accurate bead control, making it suitable for small or closely fitted components. This grade is well suited for assemblies in electronics, optics, plastic components, medical devices and transparent structures where clarity, speed and reliable adhesion are essential.
