Addition compound which is suitable as wetting agent and dispersant and can be obtained by reaction of A) polyepoxides with B) at least one aliphatic and/or araliphatic primary amine of the general formula (I) H2N-R where R = alkyl, cycloalkyl, aryl or aralkyl and the primary amine can bear further functional groups selected from among -OH, tertiary amine or carboxyl, and subsequent addition C) of at least one modified isocyanate of the general formula (IIa) and/or (IIb), where R3 = alkyl, cycloalkyl, aryl or aralkyl, R1 and R2 are each, independently of one another, H, alkyl or aryl, X = alkylene, cycloalkylene and/or aralkylene, Y = alkylene and/or cycloalkylene and n and m are independent of one another and the sum n+m is >= 2, to form a urethane.
L'invention concerne un composé d'addition s'utilisant comme agent réticulant et dispersant, obtenu par réaction de A) polyépoxydes avec B) au moins une amine primaire aliphatique et/ou araliphatique de formule générale (I) H désignant <SUB>2</SUB>N-R, R = alkyle, cycloalkyle, aryle et aralkyle, l'amine primaire pouvant également porter d'autres groupes fonctionnels sélectionnés parmi -OH, amine tertiaire ou carboxyle et par addition subséquente C) d'au moins un isocyanate modifié de formule générale (IIa) et/ou (IIb), R<SUP>3</SUP> = alkyle, cycloalkyle, aryle ou aralkyle; R1 et r2 désignant indépendamment l'un de l'autre, H, alkyle et/ou aryle, X = alkylène, cycloalkylène et/ou aralkylène, Y = alkylène et/ou cycloalkylène et n et m étant indépendants l'un de l'autre, la somme n+m = 2, de manière à former un uréthane.
