Solvent-based aerosol designed to remove chemical gaskets, gasket cements and
conventional gasket materials from metal.
When it comes to removing baked-on gaskets from metal surfaces, LOCTITE® SF
790 is the way to go. This methylene-chloride-based formula is ideal for lifting off
chemical gaskets, gasket cements and sealants, as well as paint and varnish. Its
aerosol spray means you can apply to intricate shapes with maximum
penetration, and the product won’t run off – even on vertical surfaces.
