Abstract:
An acryloxy-functional silicone composition curable by high-energy radiation, which is characterized by excellent storage stability of the composition and by improved resistance to scratching, transparency, water repellency, and adhesiveness in a hard cured coating film produced from the aforementioned composition. This composition comprises (A) a polyfunctional acrylate of at least one type; an amino-modified organopolysiloxane (B) or a product (F) of a Michael addition reaction between at least one type of a polyfunctional acrylate and amino-modified organopolysiloxane; (C) an organoalkoxysilane having an aliphatic unsaturated bond, (D) a colloidal silica; and (E) an alcohol-containing organic solvent.

Abstract:
A silicone-polyester composition and a process of forming a silicone-polyester composition are provided. The silicone part of the silicone-polyester composition contains Tand Q units and is free of D units. A polyester precursor and a silicone precursor are mixed and reacted together so as to form a silicone-polyester composition wherein the silicone part contains T, Q units and optionally Tunits. The silicone-polyester composition can be used to form a coating on a substrate, and the substrate is made of aluminum, stainless steel, iron, plastics or glass.
