Anaerobic adhesives and sealants cure in the absence of air or oxygen. They are designed for fastening and sealing applications in which a tight seal must be formed without light, heat or oxygen. Substrate or material compatibility is an important factor to consider when selecting anaerobic adhesives. Some products adhere to ceramics or glass, concrete or masonry, metal, paper, plastic, rubber or porous surfaces. Others are compatible with substrates or materials made from composites, textiles, fabrics, wood, rubber, or elastomers. Products that can bond dissimilar substrates such as metal to rubber are also available.
