Ceramic adhesives are a type of adhesive specially designed to bond ceramics, graphites, and similar materials that must withstand very high temperatures, something conventional organic adhesives may not be equipped to handle. Since ceramics are very brittle, ceramic adhesives are toughened and resistant to differing thermal expansion rates experienced between substrates. Sometimes described as adhesive cement, these materials exhibit high electrical and chemical resistance. Ellsworth Adhesives offers ceramic adhesives from top suppliers like Sauereisen.
