Abstract
A peroxy catalyst activator is dissolved in a methyl methacrylate, ethyl methacrylate or styrene lacquer containing, in addition, an adhesion promotor, e.g., an acrylic or methacrylic compound such as the carboxylic acids, amides esters having in the ester moiety amino groups or epoxy groups. The lacquer comprises a copolymer of the monomers dissolved in a volatile liquid solvent such as a mixture of toluene and isopropanol. In use, the lacquer containing the activator is applied to at least one of two substrates and allowed to dry. Thereafter, an adhesive composition containing peroxy catalyst is applied to at least one substrate and both substrates are brought into contact and held until the adhesive bond is formed. The lacquer acts to seal porous substrates and permits the cure to take place rapidly without air inhibition. It forms a surface which retains its activity over a long time period, running into years. Thus, component parts may be coated with the lacquer and stored until needed.
