LOCTITE AA 3105
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Low-Viscosity Close-Fit Assembly
- Sub-5-Second Light Fixture
- Flexible Light-Cured Bonding
Product Description
LOCTITE AA 3105 is a one-part transparent acrylated-urethane adhesive cured by UV or visible light. Its low viscosity of 200 to 400 mPa s at 25 deg C suits close-fitting assemblies, including rigid or flexible PVC bonded to polycarbonate and polycarbonate joined to flexible PVC tubing. Under specified light sources, polycarbonate-to-PVC joints fixture in less than five seconds, while glass slides fixture in 15 seconds maximum. The cured material has 265% elongation at break and a Shore D hardness of 64 after exposure at 30 mW/cm^2 and 365 nm for 80 seconds. Applications also include glass, plastics, and metals when sufficient light reaches the bondline.
Key features
- Low-viscosity close-fit assembly: Viscosity of 200 to 400 mPa s supports close-fitting PVC-to-polycarbonate assemblies.
- Fast light fixture: Polycarbonate-to-PVC joints fixture in less than five seconds under the specified UV/visible-light conditions.
- Flexible cured material: Cured elongation at break is 265% by ISO 527-3, with Shore D hardness of 64.
Applications
Applications include rigid or flexible PVC bonded to polycarbonate, polycarbonate joined to flexible PVC tubing, and bonding glass, plastics, or metals where light reaches the bondline.
