1 SCOPE.

An anaerobic, dimethylacrylate polyester resin base liquid compound that solidifies by polymerization (not by solvent evaporation) into a tough plastic when confined between closely fitted metal surfaces, producing an effective seal against lealmge and high shear strength resistance to loosening. This material may be used on slightly oiled cadmium and zinc plated, black oxide, and phosphate and oil coated parts and still obtain satisfactory properties. This material is intended for sealing flanges and cylindrical parts and for locking and sealing large diameter fasteners and studs for fluid pressure resistance or to prevent loosening under shock and vibration or a combination of both.
