Acetone-based, non-CFC, surface activator thoroughly cleans and prepares metal surfaces for rapid, high strength curing of Loctite anaerobic adhesives and sealants. Prevents loosening of scope mounts and rings caused by poor screw preparation. Especially useful for stainless steel, aluminum, blued, anodized, and other inert surfaces. Use also to speed cure time where temperatures are below 59degF (15degC) and with parts having large bond gaps. Mfg: Loctite SPECS: 1.75 fl. oz. (52mL) bottle.
