Anaerobic Adhesives

The anaerobic adhesive is an integral part of the entire machines' fastening system that will prevent all the screws, bolts, nuts and fasteners from dislodging during operation due to vibration or severe movement.  Without the presence of air during the application process, it will allow the adhesive to set and cure at the specified time that yields high torque strength, able to resist most industrial chemicals, automotive oils, hydraulic fluids and high temperature, 

Sonlok® anaerobic adhesives are designed and produced to fulfill the most demanding applications in the field of Automotive Assembly, Oil & Gas, Micro Motors Assembly, Valve & Pipe Sealings, Electrical Appliances and many more industries that require to lock, seal, gap-fill and bond all the metal fasteners and screws from loosening during operations. 

Anaerobic adhesives fill the gaps between metal components in an assembly (for example, a nut and bolt assembly). It is because of this property that they are used to augment the seal or hold components of a mechanical assembly together - all these applications usually require high shear strength.

Sonlok® anaerobic adhesives part of Parson Adhesive Inc's product portfolio is one of the leading manufacturers for a wide range of high-quality adhesives for industrial engineering applications.
