LOCTITE 4305
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Rapid Dual-Cure Surface Bonding
- Fast 5-Second Tack-Free Response
- Plastics, Rubbers and Metals Bonding
Product Description
LOCTITE 4305 is a one-part ethyl cyanoacrylate adhesive with photoinitiator for UV/visible light cure and secondary humidity cure. Exposed surfaces can reach a tack-free state in 5 seconds or less under specified 365 or 400 nm light conditions, while humidity provides a secondary path for non-UV regions. The material is a transparent light-yellow-green to dark-blue-green liquid with a typical viscosity of 600 to 1,200 mPa s at 25 deg C. It bonds plastics, rubbers and metals where rapid fixturing, fillet cure or surface cure is required.
Key features
- Light-and-humidity cure: UV/visible light cures exposed surfaces, with humidity as the secondary cure mechanism.
- Fast tack-free response: Specified 365 or 400 nm light conditions produce a tack-free surface in 5 seconds or less.
- Multi-substrate bonding: Bonding applications include plastics, rubbers and metals.
Applications
Rapid bonding of plastics, rubbers and metals in assemblies requiring rapid fixturing, fillet cure or exposed-surface cure.
