3M Scotch-Weld Threadlocker TL42, Blue, 50 mL Bottle 1.69 fl oz/50 mL

PRODUCT DESCRIPTION 3M Scotch-Weld Threadlocker TL42 provides vibration, corrosion and shock resistance for fasteners in assembled form. This blue, medium removal torque anaerobic adhesive is dispensed as a one-component, medium 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 TL42 Blue provides vibration, corrosion, and shock resistance for 1/4 - 3/4"/ 6.4 - 19 mm fasteners in assembled form. This is the medium-strength member of a family of anaerobic adhesives by 3M, dispensed as a one-component product. It hardens and seals threaded assemblies 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 the bottle. The anaerobic formulation begins to cure quickly into a polymer that seals, secures, and retains. The medium strength adhesive loosens when needed with regular hand tools. Scotch-Weld Threadlocker TL42 Blue is effective for locking, vibration dampening, threadlocking, sealing, adhering, gluing, and bonding threaded assemblies. 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 to Military Specification, MIL-S-46163A.Typical Cured Physical PropertiesStrength Medium Fastener Size Range 1/4 - 3/4" - 19 mm Breakaway Torque Range (in.lbs) 70 - 60 Prevail Torque Range (in.lbs) 20 - 90 Temperature Range -65 - 300° F/ -54 - 150° C What Are Anaerobic AdhesivesAnaerobic 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.
