  • Publication number: 20210363382
    Abstract: The invention relates to a two-component coating composition comprising i) a base component comprising: (A) a diamine resin with two secondary amine groups of general formula (b2)-NH-(b1)-NH-(b2) wherein (b1) is a cycloaliphatic hydrocarbon group, preferably a cycloaliphatic hydrocarbon group with 5 to 18 carbon atoms; and (b2) is, independently, selected from the group consisting of —Cnh2n-CN wherein n is an integer in the range of from 2 to 6, —CH2CH2—C(O)—O—CmH(2m?1) or —CH2CH(CH3)—C(O)—O—CmH(2m+1) wherein m is an integer in the range of from 1 to 6, and optionally halogenated alkyl radicals with 2 to 10 carbon atoms; and ii) a curing component comprising: (B) a polyisocyanate prepolymer having two free isocyanate groups and an isocyanate content in the range of from 3 wt % to 9 wt %, based on solid weight of the polyisocyanate prepolymer; and (C) optionally up to 3 wt % of a polyisocyanate with more than two free isocyanate groups, based on the total weight of polyisocyanates (B) and (C), wherein the two-

  • Patent number: 10370559
    Abstract: The present invention relates to a two-component coating composition comprising (1) a paint base component comprising (A) at least one polycarbonate diol, (B) at least one polyaspartic ester, and (C) at least one filler modified with at least one organosilane, and (2) a hardener component comprising (D) at least one hexamethylene diisocyanate isocyanurate containing aliphatic polyester groups and having an isocyanate content of 5% to 23%. The present invention also relates to a method for producing a coating using the coating composition, and to the coatings produced accordingly.

  • Publication number: 20190100636
    Abstract: The present invention relates to a process for repairing a coating film by applying an adhesion primer comprising a hydroxy-functional (meth)acrylate resin, a hydroxy-functional epoxy resin, a polyisocyanate, and an epoxy-functional organosilane directly to a substrate that is a substrate body with an original coating that has defects, to form an adhesion-promoting film and, applying at least one further layer of coating to the resultant adhesion-promoting film. The invention further relates to the use of the adhesion primer to improve the adherence of a further coating layer to such substrate, preferably to a substrate with a substrate body of glass fiber-reinforced unsaturated polyester resin, of glass fiber-reinforced epoxy resin, or of glass fiber-reinforced vinyl ester resin, wherein the further coating layer preferably is a polyurethane-based coating. The present invention further relates to a substrate coated with a coating film that has been repaired according to such a process.
