Abstract: Anaerobic curable compositions, such as adhesives and sealants, containing blocked dicarboxylic acid compounds are provided. The blocked dicarboxylic acid compounds are labile dicarboxylic acid compounds having two acetal linkages, which cleave to release the underlying dicarboxylic acid during anaerobic cure. In this way, the dicarboxylic acid can participate in the anaerobic cure of the composition when the blocking group is released.

Abstract: The present invention relates to anaerobic curable compositions, such as adhesives and sealants, containing blocked acrylic acid compounds. The blocked acrylic acid compounds are labile (meth)acrylic acid compounds having an acetal linkage, which cleaves to release (meth)acrylic acid during anaerobic cure. In this way, the block acrylic acid compounds acts as an adhesion promoter thereby promoting adhesion to various substrates.
