• Low viscosity
• Especially recommended for applications with passive metals or inert surfaces
• Solvent-free
• Suitable where prevailing temperatures are as low as <+59 °F (<+15 °C)
• Also recommended for large gaps

Solvent-free surface activator composed of copper salt and aliphatic amine which increases the cure speed of LOCTITE anaerobic products.
LOCTITE® SF 7090 is a dark blue-green, low viscosity, reactive monomer-based, solvent-free surface activator composed of copper salt and aliphatic amine which increases the cure speed of LOCTITE anaerobic products. It is especially recommended for applications with passive metals or inert surfaces, with large bond gaps or where prevailing temperatures are as low as <+59 °F (<+15 °C).
