The activator speeds up the curing process of WEICON Contact Cyanoacrylate Adhesives. When applied to absorbing surfaces, e.g. wood or foam etc., and all chemically-treated surfaces, e.g. zinc galvanized metals etc., the activator’s effectiveness lasts approx. one minute. On non-absorbent surfaces, the activator's effectiveness lasts up to approx. 12 hours. Use is recommendable with: highly viscous WEICON Contact types, large thickness of the adhesive layer, absorbing and porous surfaces, passive materials (alkaline surfaces, like for example zinc coated metal parts), disadvantageous environmental conditions (low temperatures, low air humidity < 30%).

LOCTITE® SF 7458 is colorless, amine-free, solvent-based surface activator liquid used to increase the cure speed of LOCTITE cyanoacrylate adhesives, either pre- or post-applied. If pre-applied, it can be detected by fluorescence. It has good on-part life and is suited for post-application on cyanoacrylate adhesives. It is particularly suited to applications where aesthetics and speed of cure are essential.

• General purpose
• For all substrates
• Good on-part life - can be pre- or post-applied
• Low odor
• Provides good aesthetic appearance of the bondline
• minimizes post-cure white discoloring
