Eliminates the Need for Pre-Cut Gaskets
Our 3M™ Scotch-Weld™ High Temperature Gasket Maker GM18 can be applied straight from the tube or by tracing, roll coating, or screen printing to provide an instant low pressure seal, eliminating the need for pre-cut gaskets, reducing weight, inventory and costs. In the absence of oxygen and in the presence of metal, this modified urethane acrylate (in paste form) cures quickly to a polymer that seals, secures, and retains. 3M Scotch-Weld High Temperature Gasket Maker GM18 withstands temperatures as high as 300?F (148?C) and does not shrink, crack, sag or run for use on rigid flanges and to seal metal assemblies.
Recommended Applications
- Vehicle repair and maintenance
- Gearbox and engine casings
- Fuel and water pumps
- Auto thermostats
- Air and liquid filters
- Fluid handling equipment
- Heat exchangers
- Ball joints
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.
