ABSTRACT:
In an adhesive having two curable components designed to be coated in separate layers on one or more of two surfaces to be joined, and cured upon contact of the layers with each other, one component is a curable liquid primer having a viscosity of at least 800 cps but no more than about 50,000 cps at 23.degree. C., and the second component is a paste having a viscosity of at least 100,000 cps at 23.degree. C. The primer is formulated with a curable liquid monomer component of which at least 30% is an alkoxy alkyl methacrylate, any balance of curable monomer in the primer comprising monomer that is capable of copolymerizing with the first-named monomer and/or cross-linking with it. Also covers the method for joining together two irregular surfaces, utilizing such an adhesive formulation. Particularly intended for orthodontic adhesive applications.
