Abstract

An improved process for manufacturing a dual cure anaerobic/ultraviolet adhesive. The process includes the first step of mixing a polymerizable (meth)acrylate ester monomer, such as methacrylic acid, a chelating agent and an accelerator. The second step is heating the mixture sufficiently to provide anaerobic curing properties. Next, one or more photoinitiators are added to the composition. No chelating agent is added during the addition of the photoinitiators.
