Anaerobic adhesives are single component materials which cure in the absence of oxygen and in the presence of metal ions (iron or steel). If the adhesive is in contact with the air, the adhesives will not cure. When the adhesive becomes completed deprived of oxygen, the curing process begins rapidly.
