Applicable Base Polymer Properties
Anaerobic adhesives and sealants remain liquid in the presence of oxygen. When isolated from oxygen it rapidly crosslinks or hardens to form a tough, “cured” polymer that will bond to many metals. They are essentially monomeric, thin liquids that polymerize to form a tough plastic bond when confined between closely fitting metal joints. Anaerobic adhesives are mainly used for metal bonding. The substrates supply the catalytic metal ions, and the absence of oxygen, a condition for the curing reaction, is guaranteed. Major industrial applications are mostly found in mechanical engineering.
