3M™ Scotch-Weld™ Gasket Maker GM10 is a red, rigid, single-component anaerobic sealant formulated to replace pre-cut gaskets and O-rings or to use as form-in-place gaskets. They cure at room temperature and seal rigid assemblies of any shape or size. They can be used to fill pits, scratches, and gouges in the flange surface without having to grind or skim the mating surfaces.
Our 3M™ Scotch-Weld™ High Temperature Gasket Maker GM10 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 GM10 withstands temperatures as high as 400°F (204°C), and does not shrink, crack, sag or run for use on rigid flanges, and to seal metal assemblies. 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.
