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.
Starting one to two threads from leading edge of pipe, apply a 360° bead to cover three thread roots. For bigger threads, apply both on male and female threads. (Recommended dispensing equipment: LOCTITE® Pro Pump, LOCTITE® 50 ml or 250 ml Hand Pump, or Peristaltic handgun 97001.)
Assemble fittings using wrench tightening in accordance with manufacturers' recommendations.
Disassemble with standard hand tools. If not possible, apply localized heat to approximately 260°C/500°F and disassemble while hot.
FAQ
The standard continuous operating temperature range for LOCTITE® anaerobic adhesives is -65° to +300°F (-55°C to +150°C). Depending on the specific application requirements, high-performance grades are also available offering increased temperature resistance. Please consult with the Henkel technical team for availability and grade selection.
Yes, Henkel anaerobic adhesives become highly resistant thermoset polymers once cured, making them suitable for a vast number of applications. Many Henkel silicone adhesives offer excellent resistance to standard media like water/glycol, amongst other solutions. Consult our online product resources or contact our technical teams for further information.
All adhesives are compatible with metal substrates although bond strength and durability will vary depending on the technology selected. Anaerobic adhesives may cause stress-cracking in some sensitive polymers and therefore should generally be avoided on plastic parts. Consult Henkel technical teams for further advice as needed.
All necessary H&S measures and PPE (personal protection equipment) requirements can be found on the product material safety data sheet, all of which are available via our website.
