Claim:
A coating composition comprising a film forming binder and an organic liquid carrier wherein the binder comprises a nucleophilic component and an electrophilic component wherein said nucleophilic component comprises an alkoxylated amine and said electrophilic component comprises an organic polyisocyanate; said alkoxylated amine has the Formula (I) (A)[N(R 1 H) 2 ] p ; Formula (I) wherein p is a number from 2 to 6; wherein each R 1 is independently [—CHR 2 —CHR 3 —O—] n with n equal to 1, 2, 3 or 4; wherein (A) is a cycloaliphatic fragment having the formula of: (i) Formula (II), (ii) Formula (III), or (iii) mixtures of Formula (II) and Formula (III); wherein Formula (II) and Formula (III), resrpectively, are: the exact point of attachment and orientation of the —CH 2 — group (which also connects to an amine nitrogen atom in Formula (I)) and the R 20 , R 21 , and R 22 groups to the norbornane skeleton can vary and mixtures of compounds and isomers are commonly utilized by this invention; the —(CH 2 ) m — group in Formula (II) attaches to an amine nitrogen atom in Formula (I); k equals 0, 1 or 2 and, when k equals 1 or 2, the additional bridging CH 2 group(s) may be on the same or opposite side with respect to the first bridging CH 2 group; B=(—(CH 2 ) t —(CH)—(CH 2 ) s —) r , r=0 or 1, s+t=1 to 16, the —(CH)— group also connects to —(CH 2 ) m —; when r=1, B forms a ring connecting to the norbornane skeleton in place of one of R 20 , R 21 or R 22 ; R 20 , R 21 , and R 22 can be the same or different and are each independently H, a C 1 to C 20 alkyl group, or a phenyl group; and m=1, 2, 3, or 4; Formula (III) has the structure of the exact point of attachment to the cycloaliphatic ring and the orientation of each —(CH 2 ) y — group, each of which also connects to an amine nitrogen atom, with respect to each other can vary; u=1–11; w=2–6; y=0–5; and if u=1, w=2, y≠1; and if u=1, w=2, y=0, R 2 or R 3 or both cannot be H, CH 3 , C 2 H 5 , CH 2 (CH 2 ) k CH 3 with k=1–5, or C 6 H 11 ; and wherein; and R 2 and R 3 are each independently H, a C 1 to C 20 alkyl group, a phenyl group, a C 6 to C 20 aryl group substituted with a C 1 –C 12 alkyl group, a —CH 2 —O—R 4 group with R 4 equal to a C 1 –C 12 alkyl group or a phenyl group, or R 2 and R 3 are connected and form a cycloaliphatic group by an alkylene chain (—(CH 2 ) q —, q=3 to 16).
