Food Release Coating Patents (Class 523/101)
  • Patent number: 9410004
    Abstract: A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.

  • Patent number: 8809416
    Abstract: The invention relates to a waterborne coating composition comprising between 10 and 50% by weight of a water-dispersible and hydrophobic polyester resin, between 50 and 90% by weight of a metal salt of a fatty acid (with the amounts being based on the total solids content in the waterborne coating composition), and a base in an amount of between 70% and 130% of the number of carboxylic acid groups in the resin. It furthermore relates to a process for the preparation of said waterborne coating composition, and to its use.

  • Patent number: 6103802
    Abstract: This invention relates to water-based release coating compositions. More particularly, the invention relates to compositions for coating ovenable and dual-ovenable paperboard. Food trays made from this coated paperboard have superior grease resistance, high temperature resistance, and excellent food release properties--characteristics which make these trays particularly suitable for use in baking applications.

  • Patent number: 5248774
    Abstract: Perylenetetracarboxylic diimides which contain a radical in the same molecule on one imide nitrogen which acts as an anion but contain a radical on the other imide nitrogen which acts as a cation, and on this basis form inner salts, are available by reaction of sulfo-containing alkylamines with perylenetetracarboxylic monoanhydride monoalkylaminoalkylimides or by reaction of alkylaminoalkylamines with perylenetetracarboxylic monoanhydride monosulfoalkylimides. As a result of their characteristic structural principle, these novel perylene compounds have excellent dispersing properties, in particular for pigments of the same chemical classes of compounds and can even be used themselves as pigments (colorants) depending on the substituent.

  • Patent number: 4504717
    Abstract: A self-cleaning coating film is formed using a self-cleaning coating composition including an oxidation, catalyst mixed within a composition including silicone synthetic resin and an organic solvent. The oxidation catalyst includes at least one element selected from a metal such as a noble metal and a metal oxide such as manganese dioxide, copper oxide, iron oxide, nickel oxide, chrome oxide, and the like. The metal is blended with a powder made of alumina, or the like, in the range of about 0.1 to 1.0 weight %. The diameter of the particles of the powder is on the order of about 40 to 300.mu.. The powder is mixed with the composition in the range of about 5 to 100 weight %. The metal oxide is present in the composition at about 50 weight %. The self-cleaning coating film is formed at about 40 to 300.mu. thickness. The thus formed self-cleaning coating film is exposed to an elevated temperature of about 300.degree. to 400.degree.

  • Patent number: 4409354
    Abstract: The present invention relates to a fluorinated resin coating composition comprising (a) a fluorinated resin, (b) micaceous iron oxide and (c) a liquid carrier. When the composition of the invention is used as a primer, an auxiliary agent for adhesion is necessitated as the supplemental component in addition to the components (a), (b) and (c). The composition of the invention can afford an excellent wear-resistance and is especially suitable for coating of inner surfaces of cooking utensils. The scratch-resistance of the coating film formed on a cooking utensil is greatly improved especially when the composition is employed for top coating. Sufficient improvement can be also attained in case of using the composition of the invention as a primer.
