Abstract:
Novel coatings are disclosed prepared by electropolymerization of non-fluorinated conducting pre-grafted hydrophobic electropolymerizable monomers onto a conducting layer of a substrate, where the electropolymerized coating exhibit both unique reversible wettability and electro-optical properties. The coating may also include one or more layers of polymer particles upon which the non-fluorinated conducting pre-grafted hydrophobic electropolymerizable monomers are polymerized imparting a submicron structure to the coating. Methods for making and using the coatings are also disclosed.
Abstract:
Die Erfindung betrifft Beschichtungsmittel, enthaltend mindestens ein Polymerisat (P1), mindestens ein mit Polymerisat (P1) in fester Phase unverträgliches Polymerisat (P2) und/oder ein mit dem Polymerisat (P1) in fester Phase unverträgliches Vernetzungsmittel (V), wobei die Polymerisate (P1) und/oder (P2) mindestens eine funktionelle Gruppe (a) aufweisen, welche beim Aushärten des Beschichtungsmittels unter Ausbildung kovalenter Bindungen reagiert, wobei das Beschichtungsmittel 0,1 bis 30 Gew.-%, bezogen auf die nichtflüchtigen Bestandteile des Beschichtungsmittels, elektrisch geladener anorganischer Teilchen (AT) enthält, deren mittlerer Teilchendurchmesser (D) 50 beträgt. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung steinschlagfester OEM-Schichtverbunde, bestehend aus einer direkt auf dem Substrat aufgebrachten Korrosionsschutzschicht, einer Füllerschicht und einer abschließenden Decklackschicht, vorzugsweise bestehend aus einer Basislackschicht und einer abschließenden Klarlackschicht, wobei mindestens eine Schicht aus dem vorbezeichneten Beschichtungsmittel gebildet wird.
Abstract:
The invention relates to dispersion coloring substances with a PVK > 40 % which contain a preparation as a binding agent. The preparation comprises at least one aqueous polymerizate dispersion as component A. The polymerizate P of said dispersion comprises carbonyl groups. As component B, the preparation comprises at least one compound with at least two reactive NH2-groups opposite the carbonyl groups of the polymer of component A. The invention also relates to the application of such preparations in order to improve wet abrasion resistance.
Abstract:
The invention relates to a bonding agent composition suitable for a coating agent. Said composition is characterized in that it contains one or more carboxy-functional polymers, one or more compounds with an epoxide function in the molecule, one or more polyols with at least two hydroxyl functions in the molecule, which are different from constituent (A), optionally having hydroxy functions, with hydroxyl groups having cross-linked constituents upon formation of ether and/or a triazine based cross-linking agent, optionally one or more polyisocyanates which can also be optionally masked, optionally an anhydride constituent and optionally one or more catalysts for catalysis of carboxyl and epoxide group reaction.
Abstract:
The present application relates to a coating composition, a process for preparing the coating composition and an article containing a coating formed by the coating composition. It relates in particular to a dual-curing coating system, comprising: a film-forming resin composition comprising an aqueous dispersion of at least one carboxyl functional polymer; a first crosslinking agent comprising an epoxy silane; and a second crosslinking agent comprising an isocyanate.
