Anaerobic adhesives are liquid resins polymerising when placed between two close fitting metal surfaces. The adhesive fills all microscopic crevices of the metal surfaces providing better stress distribution on the full joint surface. The cured adhesive gives an excellent seal against water, gas, oils, industrial fluids and chemicals. The fixture time is influenced by the gap between the surfaces, the kind of metal, surface treatments and temperature. Cure speed can vary from a few minutes to over an hour. The operating temperature range isbetween –50 / + 150 °C up to + 230°C for special grades.
