## Overview

3M Scotch-Weld Threadlocker TL71 is a red, high-torque anaerobic adhesive designed for industrial use to prevent nuts and bolts from loosening due to vibration. It fills and seals threads to stop corrosion, rust, and leaks, eliminating the need for additional locking components. With a long open time and fast curing, it ensures reliable, durable fastening in demanding production settings.

## Description

Product Description          3M Scotch-Weld Threadlocker TL71 provides vibration, corrosion and shock resistance for fasteners in assembled form. This red, high removal torque anaerobic adhesive is dispensed as a one-component, low viscosity product. This long open time anaerobic adhesive cures quickly in the absence of air when parts are assembled.             From the Manufacturer          3M™ Scotch-Weld™ Threadlocker TL71 Red provides vibration, corrosion, and shock resistance for 1/2 - 1"/ 13 - 25 mm fasteners after tightening. This is the high-strength member of family of anaerobic adhesives by 3M, dispensed as a one-component product before assembly. It hardens and seals threaded assemblies with high strength retention to dampen vibration and prevent loosening or leakage of secured fasteners. Applying this adhesive to fasteners before tightening seals out moisture and prevents corrosion. Application is fast and easy with just a targeted squeeze of a bottle. The adhesive begins to cure in the absence of oxygen and in the presence of metal. The anaerobic formulation begins to cure quickly into a polymer that seals, secures, and retains. Scotch-Weld Threadlocker TL71 Red is effective for locking, vibration dampening, threadlocking, sealing, adhering, gluing, and bonding. Places where it is useful include machine tool access bolts, and hydraulic system bolts, gear box/driveshaft bolts, bearing cover cap screws, countersunk screws, and conveyor roller bolts. Tested Military Specification: MIL-S-46163A.Typical Cured Physical Properties  Strength Medium Fastener Size Range 1/2 - 31"/ 25 mm Breakaway Torque Range (in.lbs) 180 - 410 Prevail Torque Range (in.lbs) 180 - 410 Temperature Range -65 - 300° F/ -54 - 150° C  What Are Anaerobic Adhesives?Anaerobic adhesives are uniquely formulated to cure in the absence of oxygen. The term "anaerobic" means "living without air" and when the oxygen is excluded, a chemical chain reaction begins that causes the adhesive to polymerize. Contact with metal speeds the polymerization process and rapidly accelerates the curing process, forming tough cross-linked plastic that provides aggressive adhesion with effective shear strength. More commonly referred to as threadlockers, thread sealants, retaining materials and flange sealants, these adhesives are often used to enhance the seal, or holding force, in the threads of joined fastener systems such as nut-and-bolt assemblies. A nut-and-bolt assembly may have as little as 15 percent metal-to-metal contact and even a small amount of anaerobic adhesive readily fills any air voids between the threads and then hardens to a thermoset plastic. These unique, high-viscosity adhesives are easy to dispense, cure rapidly, and provide effective torque strength while resisting temperature and vibration and sealing out moisture and gasses to protect against corrosion. Anaerobic adhesives can decrease manufacturing costs, enhance equipment reliability, minimize aftermarket breakdown, and reduce warranty claims.About 3M Industrial Adhesives and Tapes  For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals.
