LOCTITE® SF 7452 is an organic disulfide accelerator formulated by Henkel to promote the cure of instant cyanoacrylate adhesives. It is a solvent-based solution suitable for pre- and post-application to ensure rapid fixturing.
LOCTITE® SF 7452 is a premium surface activator primarily used to accelerate the cure speed of cyanoacrylate adhesives with a 30 second dry time. It is composed of organic disulfide and acetone, providing a low viscosity transparent to slightly hazy liquid that ensures easy application and improved cosmetic appearance. As an accelerator it can significantly decrease the drying time of instant adhesives to 30 seconds, allowing for quick assemblies and repairs.
