  • Publication number: 20110269897
    Abstract: The invention relates to the use of partly silanized compounds based on polyisocyanate as crosslinking agents with heightened refractive index in curable coating compositions, more particularly in clearcoat materials for automotive finishing. The invention likewise relates to a coating composition which comprises these compounds as crosslinking agents, and to the use of the coating composition to produce a coating.

  • Publication number: 20110045190
    Abstract: The present invention relates to a coating composition comprising (d) at least one binder (A) having reactive groups, (e) at least one crosslinking agent (B) which is able to react, with crosslinking with the reactive groups of the binder (A), and at least one catalyst (C) for the crosslinking of silane groups, one or more constituents (A) and/or (B) and/or at least one further constituent of the coating composition containing hydrolyzable silane groups, wherein the catalyst (C) is a phosphoric acid compound, more particularly phosphoric acid or phosphonic acid, which is blocked with an amine having a pKb?3 and a boiling point >100° C.

  • Publication number: 20100143596
    Abstract: Disclosed are coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one compound (B) having isocyanate groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, said catalyst (D) comprising phosphorus. It is an aspect of the disclosed coating compositions that (i) one or more constituents of the coating composition contain hydrolyzable silane groups and (ii) the coating composition can be finally cured to a coating which has statistically distributed regions of an Si—O—Si network.

  • Publication number: 20100015344
    Abstract: Disclosed are coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one compound (B) having free and/or blocked isocyanate groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, where (i) one or more constituents of the coating composition contain hydrolyzable silane groups and (iii) the coating composition can be finally cured to a coating which has statistically distributed regions of an Si—O—Si network. The finally cured coating obtained from the coating composition has a post-crosslinking index (PCI) of less than 2, wherein (PCI) is defined as the ratio of the storage modulus E?(200) at 200° C. to the minimum of the storage modulus E?(min) at a temperature above the measured glass transition temperature Tg.
