LOCTITE® SF 7031 is a single component non-CFC solvent based formulation for activating of surfaces to be bonded with LOCTITE® cyanoacrylate adhesives. The product is recommended as a final pre-assembly treatment for all surfaces to be bonded with Loctite® cyanoacrylate adhesives. LOCTITE® SF 7031 is applied after cleaning. Typical applications include irregular or porous substrates where localized large gaps may exist. These gaps will contain larger volumes of adhesives which will cure slowly in the absence of activator
