Promotes Adhesion of Threadlockers, Pipe Sealants, Retaining Compounds and Gasket Makers 3M™ Scotch-Weld™ Anaerobic Activator AC649 increases the cure rate of anaerobic adhesives, especially on inactive metals, such as plated parts, anodized aluminum, stainless and galvanized steel. It can be pre-applied up to 30 days in advance and can be used with 3M™ Scotch-Weld™ Threadlockers, Pipe Sealants, Retaining Compounds and Gasket Makers. Recommended Applications Locking Vibration damping Threadlocking Sealing Adhering Gluing Bonding Understanding 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, pipe sealants, retaining compounds, and gasket makers, 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% 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 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.
