Fast answers to formulation and application questions.
LOCTITE® SF 194500 is an anaerobic activator compound designed to accelerate the curing process of LOCTITE® anaerobic adhesives, in low-activity metal assemblies where difficult-to-bond substrate, like galvanized steel and zinc electroplated surfaces, are used. This low-viscosity liquid organocopper primer contains a solvent-free reactive methacrylate monomer base with positive fluorescence under UV. It can be cured via copolymerization to provide durable bond integrity.
Slow cure speed of LOCTITE® anaerobic products
Poor adhesion to difficult to bond materials
Coating difficult materials, such as galvanized steel or zinc electroplated surfaces
