LOCTITE 7451
Harmonization Code : 38159000 | Unspecified reaction initiators, accelerators, and catalytic preparations
Main features
- Pre- or Post-Activation Flexibility
- Very-Low-Viscosity Cyanoacrylate Application
- Rapid Cyanoacrylate Fixture Development
Product Description
LOCTITE SF 7451 is a very-low-viscosity amine-based cyanoacrylate activator in acetone for accelerating LOCTITE cyanoacrylate adhesive cure. It may be pre-applied to the bond area or post-applied over exposed adhesive, with post-application used for rapid fixturing. Typical drying time is up to 30 seconds at 20 deg C, and on-part life is up to 1 minute. In an ISO 4587 test on degreased steel with LOCTITE 495 and single-side activation, fixture time was up to 15 seconds. Surface activation should be followed by adhesive application immediately after drying or within 45 seconds.
Key features
- Pre- and post-assembly activation: Can be applied before bonding or over exposed cyanoacrylate after assembly.
- Very low viscosity: Typical viscosity is 0.3 to 0.5 mPa s at 20 deg C.
- Rapid fixture development: Fixture time is up to 15 seconds with LOCTITE 495 on degreased steel using single-side activation under ISO 4587.
