    • Halogenated resin compositions are prepared without using halogen acids by combining at least one silicone intermediate, with an optional silane, an organic halogen-containing ingredient having functional groups selected from the group consisting of hydroxy, amine, and carboxyl groups, and a resin selected from the group consisting of hydroxy- and epoxy-functional resins. One or more amine curing agent and/or catalyst selected from the group consisting of organometallic compounds, acids, bases, and mixtures thereof can optionally be added to facilitate ambient temperature curing of the resulting composition. The combined ingredients undergo hydrolysis reactions to form a halogenated organooxysilane that condenses to form a cross-linked halogenated polysiloxane composition. The resin also reacts with the condensing halogenated organooxysilane to introduce itself into the cross-linked halogenated polysiloxane and, thereby form the halogenated polysiloxane resin composition. The composition is prepare without using an inorganic halogen acid, and is fully-cured at ambient temperature by exposure to atmospheric moisture to form a protective film, or alternatively a composite, having improved properties of chemical, abrasion, corrosion, weather, flame, and ultraviolet resistance.

    • Adhesive/adherend systems of this invention comprise a siloxane-modified adhesive component and a siloxane-modified adherend component. The siloxane-modified adhesive component is prepared by combining an epoxy resin with an organosilane ingredient, a polysiloxane resin, an amine hardener, an organometallic catalyst, a base catalyst, and any thickener and extender pigment. The siloxane-modified adherend component is prepared using a polysiloxane resin and may also contain other resins such epoxy, phenolic, polyester, vinyl ester, polyurethane, polyamide, melamine, furan, acrylate, thermoplastic polyvinyl chloride, polyethylene, polycarbonate, ABS, polystyrene, ethylene vinyl acetate, polyvinyl acetate, polyamide, and polypropylene resins. When placed into contact with one another, the siloxane groups in the siloxane-modified adhesive and siloxane-modified adherend components form Si--O--Si bonds between themselves to form an attachment force that both occurs at ambient temperature within a reasonable amount of time, and that is greater than otherwise possible using adhesive/adherend systems having unmodified adhesive and/or adherend components.
