PRODUCT DESCRIPTION
TAFTLOCK 43 is a fast curing, medium strength anaerobic thread locking compound ideal for bonding and sealing threads, and retaining of cylindrical parts. TAFTLOCK 43 exhibits high resistance to heat, vibrations, water, gases, oils, hydrocarbons and many chemicals.
ADVANTAGES
- Ideal for less active materials, such as stainless steel, and plated parts etc
- Ideal for fasteners between 6 to 20mm diameters.
- Locks and seals threaded joints-nuts, screws, and studs with excellent oil resistance.

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 43 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.
