How to use
Cleaning - It is recommended to use LOCTITE® SF 7070™ Cleaner & Degreaser to degrease and clean surfaces prior to applying adhesive.
Activation - If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperatures (below 5°C), use LOCTITE® SF 7649™ activator. Allow to dry.
Apply a 360° bead to the leading male thread, leaving the first thread free. For bigger threads, apply both on male and female threads.
Assemble fittings using wrench tightening in accordance with manufacturers' recommendations.
Disassemble with standard hand tools. If not possible, apply localized heat to approximately 500°F/260°C; disassemble parts while hot. For corroded or seized parts use LOCTITE® LB 8040™ Freeze and Release.
