Product Description
LOCTITE® AA 3104™ is a one-component UV and visible light-curing acrylic adhesive designed primarily for bonding rigid or flexible PVC to polycarbonate. The transparent liquid formulation cures rapidly upon exposure to ultraviolet or visible light, enabling high-speed manufacturing processes and efficient assembly operations. Its low-viscosity characteristics allow easy application in close-fitting assemblies, while the cured adhesive provides flexibility that enhances load-bearing and shock-absorbing performance. LOCTITE AA 3104 demonstrates excellent adhesion to a broad range of substrates including polycarbonate, PVC, glass, many plastics and most metals.
Key Features & Benefits
- UV and visible light-curing adhesive for rapid production processing.
- Specifically developed for bonding PVC to polycarbonate.
- Transparent formulation for aesthetically clean bond lines.
- Low-viscosity adhesive supports easy dispensing and wetting.
- Flexible cured bond enhances shock absorption and load distribution.
- One-component system requiring no mixing.
- Excellent adhesion to plastics, glass and metal substrates.
Recommended Applications
- Polycarbonate-to-PVC bonding.
- Joining flexible PVC tubing to polycarbonate components.
- Transparent plastic assembly applications.
- Glass-to-plastic and plastic-to-metal bonding.
- High-speed manufacturing processes utilizing UV curing systems.
