摘要:
The invention relates to a method for coating surfaces, to a corresponding coating, and to the use of the objects coated according to said method. According to the invention, the method has or consists of the following steps: I. providing a substrate with a cleaned surface, II. contacting and coating the surfaces with an aqueous composition in the form of a dispersion and/or suspension, VI. if necessary rinsing the organic coating, and VII. drying and/or baking the organic coating or VIII. if necessary drying the organic coating and carrying out a coating process using a similar or additional coating composition prior to a drying and/or baking process, wherein between step I and step II, the coating process is carried out using an aqueous composition in the form of a dispersion and/or suspension on the basis of a colloidal silicate sol, which incorporates multivalent metal cations, or a silane- or silicate-modified polymer and if necessary a rinsing process is carried out.

摘要:
The present invention provides a bioactive coating composition, method and devices for bodily fluid-contacting surfaces. The coating comprises a complex of Formula II: wherein R1 is an C1-18alkyl or C6-32aryl group, each R2 is independently selected from the group consisting of C1-18alkyl and C6-32aryl, R3 is N or O, n is a number from 1 to 10, and x in a number from 1 to about 30, directly bound to a heparin-activity molecule via covalent bonding, with one or more bioactive molecules bound to the heparin-activity molecule. The bioactive molecule may be an adhesive molecule such as fibronectin, a growth factor such as basic fibroblast growth factor, or any other bioactive molecule that binds, by any mechanism, to a heparin-activity molecule.
摘要:
Use of an aqueous composition, which has been prepared by dissolving (A) dihydroxypropylchitosan and (B) 1,2,3,4-butanetetracarboxylic acid (B) in an aqueous medium, makes it possible to provide articles excellent in hydrophilicity, antibacterial and deodorant activities, touch feeling, antifogging property, paper strength, dyeability, waterproofness, antifouling property and/or the like.
摘要:
Eine Kapsel, insbesondere zur Zubereitung eines Getränkes aus Getränkepulver, insbesondere von Kaffee aus Kaffeepulver, durch Einbringen von Wasser in die Kapsel, umfasst einen Pressling aus einem wenigstens ein Polysaccharid enthaltendem Pulver, wobei der Pressling mit wenigstens einer Beschichtungsschicht ummantelt ist, wobei die wenigstens eine Beschichtungsschicht ein vernetztes Polysaccharid umfasst, wobei das vernetzte Polysaccharid durch Vernetzen eines Polysaccharids mit einem Vernetzungsmittel ohne die Verwendung eines polyolen Abstandshalters erhalten wurde. Ein Verfahren zum Herstellen einer solchen Kapselumfasstdie folgenden Schritte: i) Bereitstellen eines Presslings aus einem wenigstens ein Polysaccharid enthaltendem Pulver, ii) in Kontakt bringen wenigstens eines Teils und vorzugsweise der gesamten Oberfläche des in dem Schritt i) erhaltenen Presslings mit einer Lösung eines Polysaccharids in einem Lösungsmittel oder mit einer Dispersion eines Polysaccharids in einem Dispergiermittel, iii) ggf. Entnehmen des Presslings aus der Lösung oder der Dispersion des Schritts ii), iv) in Kontakt bringen des in dem Schritt ii) oder iii) erhaltenen Presslings mit wenigstens einem Vernetzungsmittel, v) ggf. Entnehmen des Presslings aus der Lösung des Schritts iv) und vi) Trocknen des in dem Schritt iv) oder v) erhaltenen Presslings.
