PRODUCT DESCRIPTION
TAFTLOCK 71 is a fast curing, high strength anaerobic thread locking compound ideal for bonding and sealing threads, and retaining of cylindrical parts. TAFTLOCK 71 exhibits high resistance to heat, vibrations, water, gases, oils, hydrocarbons and many chemicals.
ADVANTAGES
- Ideal for transmission and engine block studs, valve sets etc
- Ideal for fasteners up to 25 mm in diameter.
- Permanent high strength, eliminates the need for double nutting and welding.
- Effectively prevents corrosion and leakage.

APPLICATION METHOD
Surfaces should be dry, clean, and free of any contamination. Thread locker should be applied to the bolt in sufficient quantity to fill threads. TAFTLOCK 71 performs the best in thin bond gaps. This thread locker is specifically formulated to give controlled friction and torque/tension ratio during assembly.
STORAGE
Anaerobic adhesives shall be ideally stored in a cool, dry place in unopened containers at room temperature between 8°C to 25°C. Please do not return any unused material to its original container.
Compliance and quality
Made under the ISO 9001 quality management system of Vitrochem Technology. RoHS declarations and Safety Data Sheets are available on request.
