LOCTITE AA 3201
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Rapid Light-Cure Fixture Development
- Thixotropic Placement Control
- Flexible Transparent Polycarbonate Bonding
Product Description
LOCTITE AA 3201 combines one-part acrylated urethane chemistry with medium, thixotropic flow for rapid UV or visible-light bonding. It forms flexible, transparent bonds and is primarily intended for polycarbonate-to-polycarbonate assemblies. The thixotropic rheology reduces liquid migration after dispensing, while light exposure can develop fixture strength in 5 to 20 seconds under the listed lamp and substrate conditions. Typical uncured viscosity is 2,500 to 5,000 mPa s at 25 deg C. Applications include bonding polycarbonate and other light-transmitting plastic assemblies, with additional adhesion data available for glass and metal substrates.
Key features
- Rapid Light Fixture: Fixture strength develops in 5 to 20 seconds under the specified light-source and substrate conditions.
- Thixotropic Placement Control: Thixotropic rheology reduces migration of the liquid adhesive after application.
- Flexible Transparent Bonds: UV or visible-light cure forms flexible, transparent bonds for supported polycarbonate assemblies.
Applications
Polycarbonate-to-polycarbonate bonding and other supported plastic, glass, and metal assemblies where light reaches the bond area.
