Anaerobic adhesives or anaerobic adhesives are a very specific group of preparations, intended for use in joining mainly metal surfaces. Anaerobic adhesives react when in contact with metal, which is their catalyst. They harden when the air supply is eliminated, while maintaining the appropriate temperature and the size of the gap used.
Anaerobic adhesives are designed to protect threaded connections against unscrewing, to seal threaded connections, to protect metal elements against vibrations. Anaerobic products also allow filling gaps between adjacent metal surfaces, ensuring high resistance of the joint against external factors. Anaerobic adhesives are also used for fixing pipe connections, for screw-nut connections, guaranteeing high strength of the joined elements.
