Anaerobic adhesive is referred to as the anaerobic adhesive is using oxygen on free radical resistance poly made of the principle of one component sealing adhesive can be used for bonding and can be used for sealing. Dangtu rubber surface is isolated from the air and in the case of fast catalytic polymerization curing at room temperature. The composition of anaerobic adhesive is more complex, with unsaturated monomers as the main components, there will be aromatic amines, phenols, aromatic hydrazine, peroxide, etc.. In recent years, the foreign anaerobic adhesive formulations continue to introduce new, getting better and better, by the machinery industry.
After the 1990s, the United States developed a one-component anaerobic standard (ASTM 5363-97), regulates the manufacture and the role of anaerobic. China also has a chemical industry standards (HG / T 3737-2004).
Anaerobic characteristics and application
(1) The majority of haplotype viscosity change a wide range of varieties, easy to select.
(2) without weighing, mixing with glue, extremely easy to use, easy to implement automation.
(3) room temperature curing, fast, high-intensity, energy-saving, low shrinkage, good sealing. After curing removable.
(4) performance, heat, pressure, low temperature resistance, chemical resistance, good impact resistance, shock absorption, anti-corrosion, anti-fog properties.
(5) does not solidify adhesive glue seam spills, easy to remove.
(6) solvent-free, low toxicity, less harmful, non-polluting.
(7) widely used, sealing, locking, holding, bonding, sealing, etc. can be used.
(8) storage stable, glue storage period is generally three years.
Because of its unique Anaerobic Anaerobic curing characteristics, can be applied to the locking, sealing, retaining, bonding, sealing and so on. Anaerobic machinery industry has become an indispensable tool for the liquid. In the aerospace, defense, automotive, machinery, electronics, electrical and other industries have a very wide range of applications.
