  • Solid siliconized polyester resin for powder coating
    Patent number: 7396893
    Abstract: The present invention pertains to a siliconized polyester resin that has a sufficiently high Tg that the siliconized polyester is a solid at room temperature. The silicone polyester preferably has a Tg of 30° C. or greater. The silicone polyester can be produced as a particulate and remain stable at room temperature. The particulate silicone polyester is suitable for use in coating compositions, including powder coating compositions. The coating can be clear or pigmented, and thus optionally can include pigment. The coating composition also includes a crosslinker. The coating composition can be ground into a powder. The powder is stable at room temperature. The powder is then capable of being coated on a suitable substrate and then baked to form a coated metal object.
    Type: Grant
