Abstract
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.
