3M™ Scotch-Weld™ metal primer 3901 is a primer designed for applications using 3M™ Scotch-Weld™ structural adhesives. This film and liquid adhesive primer is able to improve metal and glass adhesion. Additional features of this primer include improved corrosion protection and resistance to environmental exposure for metal. 3M™ Scotch-Weld™ metal primer 3901 is a 1-component, metal and glass primer designed for applications using 3M™ Scotch-Weld™ film and liquid structural adhesives. Formulated to improve metal and glass adhesion, this film and liquid adhesive primer simplifies production scheduling by protecting the cleaned surfaces until the bonding operations can be completed. This product also offers resistance to environmental exposure as well as provides improved corrosion protection to metal. 3M™ Scotch-Weld™ metal primer 3901 features low viscosity for ease of application and ensures complete wetting of the film adhesive to adhered surfaces, providing an ideal application surface. For those applications using 3M™ Scotch-Weld™ structural adhesives, 3M™ Scotch-Weld™ metal primer 3901 ensures that surfaces remain relatively free of oxidation until the bonding application is completed. Protection from and resistance to corrosion and environmental exposure is key to successful, long lasting adhesion. 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.
