Patent number: 4608421Abstract: New siloxane-polyesters, siloxane-ethers and siloxane-ether-polyesters, useful as powder coating resins, are prepared by reacting rigid diacids, neopentyl glycol, trimellitic anhydride with up to 90 percent hydroxyl functional silicone having about two .dbd.Si(R)--OH groups per molecule where R is lower alkyl or phenyl groups and the remaining silicon valences form ring-structured siloxanes. Improved powder properties, including crystallinity and tack temperatures of 50.degree.-90.degree. C., are believed to result in part from the rigidity provided by both the specific diacids and the cyclic silicones. The siloxane resins are hard at room temperature and can be powdered by methanical grinding. Powder coatings formulated from these resins are particularly suitable for coating metal and glass substrate.Type: GrantFiled: June 17, 1985Date of Patent: August 26, 1986Assignee: SCM CorporationInventor: Ju-Chui Lin
