摘要:
The present invention relates to a process for tailoring theology of an aqueous or water-borne coating composition using a system comprising an amount of a first hydrophobically modified polymer comprising a polymer backbone modified with a first hydrophobe and an amount of a second hydrophobically modified polymer comprising the first hydrophobically modified polymer further modified with a second hydrophobe. By incorporating a system comprising at least two hydrophobically modified polymers into water-borne coatings where the amount of all of the hydrophobically modified polymers are able to be independently adjusted, the resultant coatings may be tailored to attain a desired combination of Stormer or Brookfield viscosity and ICI viscosity.

A base layer is formed on the surface of metal plate, metal pipe, unbaked ceramic sheet, laminated ceramic green sheet, etc., the base layer causing a gelling reaction with inkjet-ink. The base layer improves ink acceptability for low viscosity inks such as inkjet-ink, and prevents oozing, draining, uneven thickness of an ink pattern and a resist pattern. Thus, the present invention enables to use an ink jet process for providing resist patterns for etching, etc., which has to fulfill stringent high precision requirements.
摘要:
The invention relates to coating and encapsulation composition useful for protecting core material from oxidative and/or hydrolytic damage. The coating composition comprises a lipid polymer and a lipid-based anti-oxidant, wherein the anti-oxidant is soluble in the lipid polymer.

An edible dry-powder formulation of a film coating for pharmaceuticals and confectioneries using gum acacia as a low-cost film former is provided. A cellulosic polymer such as hydroxypropyl methylcellulose is used in addition to the gum acacia. A plasticizer such as propylene glycol is also added. The resulting formulation is a dry, free flowing powder that can be put into solution and applied to a tablet or other substrate without an extended waiting period. The resulting film coating is clear, shiny, durable and extremely economical. Because the formulation is a dry powder, it has along shelf life and low shipping costs.
摘要:
A pigment product for use in a coating composition to provide a gloss coating on paper, the pigment product comprising a processed particulate kaolin having a particle size distribution such that at least about 80% by weight of the particles have an equivalent spherical diameter less than about 2 nullm and in the range of from about 15% to about 40% by weight of the particles have an equivalent spherical diameter less than about 0.25 nullm and the particles have a shape factor in the range of from about 30 to about 60 and wherein the pigment product comprises a blend of Component A: a particulate kaolin in which the particles have a shape factor of at least about 45, and Component B: a particulate kaolin in which the particles have a shape factor of less than about 20.
摘要:
An edible, hardenable coating composition is disclosed which comprises high levels of low viscosity propylene glycol alginate and a surfactant, which may additionally contain a filler, a pigment, and optionally a small amount of a secondary film former and/or a strengthening polymer. The coating composition of the present invention may be applied to pharmaceutical and veterinary solid dosage forms, confectionery, seeds, animal feed, fertilizers, pesticide tablets, and foods and provides an elegant prompt release coating which does not retard the release of active ingredients from the coated substrate.
摘要:
The invention is directed to a co-crystallized product and a method of making the product. The product comprises a polyol and a hydrogenated maltodextrin that have been co-crystallized together. The co-crystallization of polyols and hydrogenated maltodextrin according to the invention provides a sweetener product that is sucrose-free, yet has a reduced sensory cooling effect compared to the original polyol(s). The reduced sensory cooling effect is due to an increase of the heat of solution that is observed when polyols are co-crystallized with hydrogenated maltodextrin. Because the product of the invention is a sucrose-free sweetener that does not demonstrate the strong sensory cooling effect typically found with polyol sweeteners, the invention has a wide variety of applications which previously are not available for polyol sweeteners.

A heteropolysaccharide--containing glass fiber sizing composition that provides improved application uniformity when applied to hot fibers via a roll coater.
摘要:
A process for protecting a surface from non-desired contamination and for facilitating removal of said contamination from said surface, characterized by the steps: a) preparing a solution of polysaccharides containing at least two components, wherein one component is constituted by a first polysaccharide which, when precipitated from a solution by evaporation of the solvent thereof, directly forms a film and wherein the second component is constituted by a second polysaccharide which, when precipitated from a solution by evaporation of the solvent thereof, forms a film via at least partial gel formation, or by interaction with said first polysaccharide, said films being redissolvable or swellable: b) applying the solution from step a) onto said surface before subjected to contamination: c) allowing the applied solution to dry so as to form a solid film on said surface via at least partial gel formation: d) treating the film-coated surface with a liquid capable of redissolving film or provided swelling thereof: and e) removing the non-desired contamination by complete or partial removal of the film from the surface.
