M0115 has good resistance to mechanical and thermal stresses and adheres well to surfaces. It is resistant to oils, fuels, water-glycol mixtures, and corrosion. It is suitable for cylinder head gaskets in internal combustion engines, intake and exhaust manifolds, and other applications subjected to high mechanical and thermal stress.
