Abstract
An inorganic based strippable coating is provided for isolating hazardous materials. The coating is formed from a metal alkoxide material which undergoes a sol-gel reaction to form a metal oxide material. While the sol is still in a green state, the sol is applied to the surface to be protected. Any hazardous material such as nuclear contamination present on the surface is trapped within the matrix of the sol. The sol coating may be stripped from the surface while in a green state or may be allowed to harden. Once hardened, the sol forms a metal oxide coating which will deter the future accumulation of contamination.
