LOCTITE Primer SF 7701 (52 ml)

LOCTITE SF 7701 – Primer for polyolefins and difficult-to-bond plastics

LOCTITE SF 7701 is a colorless, solvent-based adhesion promoter (primer) specifically designed to permanently bond low surface energy materials such as polyethylene (PE), polypropylene (PP), PTFE (Teflon) and thermoplastic elastomers to cyanoacrylate superglues (e.g. LOCTITE 406, 460, 496).

This product is frequently used where conventional superglues do not achieve sufficient adhesion – e.g. in medical technology, electronics assembly, plastics processing or when assembling components made of PE or PP.

Areas of application

• Polyolefin bonding: Enables reliable bonding of polypropylene, polyethylene, PTFE and more.
• Medical devices: Tested according to ISO 10993 – suitable for many disposable medical products
• Electronics & Precision Mechanics: Ideal for components with a small adhesive surface and high speed
• Quality assurance: Fluoresces under UV light for easy visual inspection

Advantages at a glance

• Improves the adhesion of LOCTITE CA adhesives to difficult-to-bond plastics
• Very thin, dries in about 30 seconds
• Up to 8 hours of active use on prepared surfaces
• No impact on biocompatibility when used as intended (ISO 10993 compliant)
• Universally applicable by spraying, brushing or dipping
• Also effective as a curing accelerator – reduces fixing time to under 5 seconds.
