Abstract:
The invention relates to a substrate intended in use to contact a fouling agent, the substrate including a coating comprising polysaccharide, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate. The invention also relates to the anti -fouling coating, to apparatus comprising such coating and to related methods of reducing or preventing fouling of a substrate intended in use to contact a fouling agent.
Abstract:
The invention relates to multilayer materials for producing packaging comprising at least two films and also a layer which is printed with a packaging printing ink, said packaging printing ink comprising a certain hyperbranched polyester containing functional groups. The invention further relates to a packaging printing ink which comprises a certain hyperbranched polyester containing functional groups, and to the use of said printing ink for producing multilayer materials.
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.
Abstract:
Disclosed is a method for preparing a composite paint composition (a composition forming a coating film after the volatilization of a solvent) comprising urushiol extracted from raw lacquer. Specifically, the method comprises the steps of: mixing raw lacquer with an organic solvent and centrifuging the mixture to separate an urushiol layer dissolved in the organic solvent; heating the urushiol layer dissolved in the organic solvent so as to remove the organic solvent and water, thus extracting urushiol; mixing the extracted urushiol with composite paint to prepare a composite coating composition comprising extracted urushiol; and applying the composite paint composition comprising extracted urushiol to the surface of various materials, including wood, various plastics, metals, paper, fabrics or leathers, through various coating processes, including spray coating, roll coating, curtain coating, film coating, printing, dyeing or dipping, and curing the applied composition. Also disclosed are a composite paint composition comprising extracted urushiol, prepared according to said method, and an article coated with the composite paint composition comprising extracted urushiol. The article coated with the lacquer component urushiol, manufactured according to said method, is environment-friendly and beneficial to the health, because the lacquer component has a far- infrared ray-emitting effect, an electromagnetic wave-shielding effect and an excellent antimicrobial effect.
Abstract:
A coating composition for artificial pearls and the preparing method thereof are disclosed. The coating composition for artificial pearls comprises (by weight)1.5-6% of celluloid, 0.1-0.6% of camphor, 86-95% of mixture solvent which consists of acetone or/and ethyl acetate and butyl acetate or/and amyl acetate, and 1-8% of pigment. The coating composition for artificial pearls has the advantages of harmless to human body, environment-friendly, excellent in color and gloss, shortened dying and curing time, low cost and high productivity which is suitable for large scale manufacture.
Abstract:
Coating compositions are provided comprising: a) at least one hydroxy-containing acrylic polymer; b) at least one low molecular weight hydroxy-containing acrylic polymer; c) at least one crosslinking agent; d) at least one curing catalyst; and e) at least one cellulose mixed ester. Articles comprises the coating compositions are also provided.
Abstract:
A self-leveling finishing composition capable of providing chemically resistant low profile coatings is described. The finishing composition comprises thermoplastic resin solids and thermosetting resin solids in a weight ratio of about 0.5:1 to about 11:1 and a solvent composition comprising a solvent capable of dissolving the thermoplastic resin solids component and a solvent miscible co-solvent capable of dissolving the thermosetting resin solids. The finishing composition is applied and dried to a dry-to-touch surface which is thereafter subjected to conditions capable of initiating polymerization of the component thermosetting resin solids. The finishing composition can be used as a substitute for more expensive or more labor intensive coating compositions in existing surface finishing protocols without compromise of surface quality and chemical resistance.
Abstract:
A presente invenção refere-se a um processo aperfeiçoado para a produção de uma dispersão coloidal de nitrocelulose compatibilizada em um sistema de monômeros acrílicos polimerizados com tensoativos em um sistema à base de água sob a ação de uma força de pressão. O sistema autoemulsionável da presente invenção é caracterizado pelo látex formado pela suspensão de nitrocelulose em meio aquoso, que apresenta partículas de tamanho nanométrico, homogeneidade e, por consequência, proporciona maior poder de cobertura e nivelamento, elevada aderência, alto brilho, maior resistência química e mecânica, rápida secagem, menor retenção de água quando aplicado na composição de tintas, vernizes e seladoras para revestimento nos segmentos de impressão gráfica como flexografia e rotogravura, laminação, esmaltes de unha, metal mecânica, decorativa, vidro, couro, plástico, superfícies de madeira, massas e argamassas, tintas decorativas imobiliárias, têxteis, revestimentos de papel, sistemas de repintura automotiva, entre outras aplicações. Além de conferir propriedades de alto desempenho, o produto desta invenção é ecologicamente correto.
