Abstract:
Disclosed is a fullerene film which can be easily formed by a wet process without deteriorating the intrinsic properties of a fullerene by using a fullerene derivative as a raw material. Also disclosed are a fullerene polymer, a method for producing a fullerene film, and a method for producing a fullerene polymer. A fullerene film or a fullerene polymer maintaining the intrinsic properties of the fullerene is obtained by coating a base with a solution of a fullerene derivative and then heating the thus-obtained coating film at a temperature higher than the thermal decomposition temperature of the fullerene derivative but lower than the thermal decomposition temperature of the fullerene.
Abstract:
The invention relates to a coating material suitable for providing a substrate with an anti-biofouling coating, the coating material comprising a macromolecule comprising: (A) a macromolecular scaffold comprising a reactive group capable of undergoing a Michael type reaction between a Michael type acceptor group and a Michael type donor group, (B) at least one functional moiety attached to the macromolecular scaffold, said at least one functional moiety comprising a hydrophilic moiety, wherein the functional moiety is derivable from a Michael type reaction, involving the reactive group on the macromolecular scaffold and a reactive hydrophilic moiety and (C) at least one moiety capable of crosslinking the coating material.
Abstract:
The invention relates to coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one saturated compound (B) having free and/or blocked isocyanate groups and containing at least in part hydrolyzable silane groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, wherein the coating composition comprises as hydroxyl-containing compound (A) at least one hyperbranched, dendritic hydroxy-functional polyester in which on average at least one hydroxyl function of the polyester is esterified with at least one acid selected from the group of the isomeric C8 to C9 monocarboxylic acids. The present invention also provides a multistage coating method using these coating compositions, and also the use of the coating compositions as clearcoat material for producing multicoat effect and/or color paint systems, and use of the coating method for automotive OEM finishing and automotive refinish.
Abstract:
