ABSTRACT:
A sludge powder and sealant are prepared from paint sludge. A sludge powder is generated from a paint sludge having a volatiles content of 0-50% by weight by adding a processing filler thereto. A sealant composition is prepared by thereafter or concurrently therewith adding sealant ingredients including polymer, plasticizer, curative, and other sealant ingredients such as an adhesion promoter and sealant filler materials to the sludge powder. Alternatively, a sealant composition may be prepared by adding a paint sludge having a volatiles content of 0-50% by weight to the sealant ingredients, which may include a processing filler.
