  • Publication number: 20100203348
    Abstract: Some embodiments of the invention generally relate to a moisture barrier coating that is biodegradable and compostable. Some embodiments also relate to a coating that is dual ovenable. Such coatings may be used to increase moisture resistance and provide non-stick or release characteristics when applied to biodegradable and compostable disposable food packaging and food service items. In some embodiments, a plasticizer, an amide wax and optionally a rosin are added to a cellulose-ester-based coating to increase moisture resistance. In other embodiments, a biodegradable polymer, an amide wax, optionally a plasticizer, and optionally a rosin are added to a cellulose-ester-based coating to drastically increase moisture resistance. In still other embodiments, phospholipids or medium-chain triglycerides or increased levels of amide wax may be added to the either of the embodiments above to provide enhanced release characteristics.

  • Patent number: 7208534
    Abstract: The present invention pertains to a solvent based coating composition comprising A) at least one toner base comprising an acrylic polyol, a cellulose resin, a polyester polyol, and a pigment, B) at least one connector base comprising at least one resin compatible with the resins mentioned in toner base A), and C) at least one reducer base free of resins and pigments. It has been found that the coating composition of the present invention does not have drawbacks such as insufficient hiding, a high sensitivity for cloudiness, and a loss of brightness or color. Such drawbacks are often found in base coat compositions. Furthermore, the coating composition of the present invention provides a very flexible application window. Due to a selection of resins, additives, and/or fillers to be used in the connector base (B), the use and properties of the coating composition of the present invention can be modified.
