    摘要: The invention provides improved bonding methods and bonded laminates using multi-part adhesive compositions having first and second parts. The first part of the adhesive composition comprises free radical polymerizable monomers and a source of free radicals; the second part comprises an activator for initiation of polymerization of the monomer. According to the invention, flexible, activator carrying elements are positioned between layers of the first part to provide effective bonding between substrate surfaces which may be spaced apart from each other by relatively large gaps.

    摘要: An elastomeric expansion belt material includes an under layer having a heat resistant or insulating fabric, or matting, such as an asbestos fabric, carried by a polymerizable elastomer vulcanized to a heat shield including one or more layers of a metal foil, such as aluminum, and a polyester film, such as polyethylene terephthalate having the metal foil on the inner, or heat contacting surface. The heat shield substantially doubles the temperature resistance of the asbestos carried elastomer and substantially increases its resistance to chemically corrosive gases and particulate material.
