How to use
For best results, clean all surfaces (external and internal) with a IPA 99% and allow to dry.
Shake the product thoroughly before use. To prevent clogging in the nozzle, avoid allowing the tip to touch metal surfaces during application. For Sealing Applications, apply a 360° bead of product to the leading threads of the male fitting, leaving the first thread free, and force the material into the threads to thoroughly fill the voids. For larger threads and voids, adjust the product amount accordingly and apply a 360° bead of product on the female threads as well. Finally, assemble and tighten as required.
Remove with standard hand tools. In rare instances where hand tools are ineffective due to excessive engagement length, apply localized heat to the nut or bolt to approximately 250°C and disassemble while hot. Alternatively, apply localized heat to the entire assembly to approximately 250°C and disassemble while hot.
Cured product can be removed with a combination of soaking in a solvent and mechanical abrasion such as a wire brush.
