Anaerobic Adhesives and Sealants

This accomplished range of anaerobics contains Thread-Lockers, Thread-Sealers, Retainers and Pipe-Sealants. All of our anaerobics are manufactured in strict accordance with an ISO 9002 accredited quality system and many have gained MIL-S-46163A, ASTM D-5363 and NSF approvals.
What Are Anaerobics?
The word "Anerobic" means without air, which explains the primary cure mechanism of this group of adhesives. An Anerobic Adhesive is a single part adhesive that cures or polymerizes when deprived of oxygen. Anaerobics are designed to lock and seal metal components and fasteners and are available in a range of viscosities, from water-thin to a heavy paste.
How do they work?
An anaerobic is normally made from an acrylic monomer that contains a replenishing supply of free radicals which react with oxygen in the air, allowing the monomer to stay in a liquid form. When pressed between two surfaces the oxygen is restricted and the free radicals are forced to react with the carbon molecules of the monomer itself, forming a polymer group or chain and turning the monomer into a solid. This reaction is quickened with the introduction of a metal, which fuels and increases the production of free radical catalysts.
