Insome cases these aqueous washes can affect the cure andperformance of the adhesive.This product is not normally recommended for use on plastics(particularly thermoplastic materials where stress cracking ofthe plastic could result). Users are recommended to confirmcompatibility of the product with such substrates.Directions for use:For Assembly1. For best results, clean all surfaces (external and internal)with a LOCTITE ® cleaning solvent and allow to dry.2. If the material is an inactive metal or the cure speed is tooslow, spray all threads with Activator 7471 or 7649and allow to dry.3. Shake the product thoroughly before use.4. To prevent the product from clogging in the nozzle, do notallow the tip to touch metal surfaces during application.5. For Thru Holes, apply several drops of the product ontothe bolt at the nut engagement area.6. For Blind Holes, apply several drops of the product downthe internal threads to the bottom of the hole.7. For Sealing Applications, apply a 360° bead of productto the leading threads of the male fitting, leaving the firstthread free. Force the material into the threads tothouroughly fill the voids. For bigger threads and voids,adjust product amount accordingly and apply a 360° beadof product on the female threads also.8. Assemble and tighten as required.For Disassembly1. Remove with standard hand tools.2. In rare instances where hand tools do not work becauseof excessive engagement length, apply localized heat tonut or bolt to approximately 250 °C. Disassemble whilehot.For Cleanup1. Cured product can be removed with a combination ofsoaking in a Loctite solvent and mechanical abrasionsuch as a wire brush.Loctite Material Specification LMSLMS dated September-01, 1995.
