  • 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-
