Abstract
Abstract A coating composition to be applied to a metal casket to prevent corrosion thereof. The coating comprises a film forming matrix containing dispersed particles of an alkaline material capable of neutralizing the finite amount of organic acids contained in the casket to thereby prevent acidic corrosion of the casket. The coating can also contain an anti-oxidant to prevent oxidative corrosion of the metal casket, and a bacteriacide to prevent microbial growth within the casket. Through use of the coating, a stable, substantially neutral condition is produced in the casket.
