LOCTITE 4471
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Fast Difficult-Surface Fixturing
- Uniform-Stress Assembly Bonding
- Porous and Plated Surface Bonding
Product Description
LOCTITE 4471 is a one-part medium-viscosity ethyl cyanoacrylate instant adhesive that cures with atmospheric humidity. It is formulated for difficult-to-bond assemblies requiring uniform stress distribution and strong tension or shear performance. Typical viscosity is 500 to 750 mPa s at 25 deg C. Fixture times at 22 deg C and 50% RH range from under 5 seconds on neoprene and nitrile rubber to 2 to 5 seconds on ABS, PVC and polycarbonate. The adhesive bonds wood, leather, foamed rubber, acidic surfaces and freshly plated parts.
Key features
- Rapid fixture development: Fixture times are under 5 seconds on neoprene and nitrile rubber under specified conditions.
- Medium-viscosity control: Typical viscosity is 500 to 750 mPa s at 25 deg C by Brookfield RVT.
- Difficult-surface bonding: Supported substrates include porous materials, acidic surfaces and freshly plated parts.
Applications
Bonding wood, leather, foamed rubber, acidic surfaces and freshly plated parts.
