  • Patent number: 7776963
    Abstract: Adhesive formulations having acrylate monomer or methacrylate monomer, or mixtures thereof, and having a reducing agent and an initiator (e.g., peroxide). The formulations may include a chelating agent solution to improve storage stability and other properties. Further, the mole ratio of the initiator to the reducing agent may be adjusted to control weight loss of the adhesives during cure. Polyvinyl acetate or its derivatives may also be employed in the adhesive formulations to reduce weight loss during cure. Moreover, certain embodiments of the formulations include a toughening-agent copolymer having a glass transition temperature (of at least one domain) that is lower than ?50° C. (?58° F.). These toughening-agent copolymers may be added to the adhesive formulations to improve impact strength and other properties of the cured adhesives at lower temperatures, e.g., ?40° C. (?40° F.), while maintaining performance of the cured adhesives at higher temperatures, e.g., 82° C. (180° F.).

  • Patent number: 7479528
    Abstract: An adhesive formulation including an acrylate monomer and/or a methacrylate monomer, a chlorosulfonated polymer resin, and a reducing agent. The adhesive also includes a cycloheteroatom zirconate or a cycloheteroatom titannate, which is utilized as a cure profile regulator. Further, the adhesive includes toughening-agent copolymers having a very low Tg to increase impact strength of the cured adhesives at low temperatures.
