    摘要： A method for making a polyaspartic ester mixture in-situ comprising the sequential steps of (a) reacting a cyclic amine with an excess amount of an ester of fumaric or maleic acid to form a mixture containing first polyaspartic ester component and excess unreacted ester of fumaric or maleic acid, and (b) adding an acyclic amine to the mixture resulting from step (a) and reacting the acyclic amine with the excess ester of fumaric or maleic acid to form a second polyaspartic ester component.

    摘要： The present invention relates to two-component coating compositions containing a) a polyisocyanate component, b) an isocyanate-reactive component and c) 0.1 to 20 wt.%, based on the weight of components a) and b), of a compound containing alkoxysilane groups and urea groups corresponding to the formula (I), wherein X represents identical or different organic groups which are inert to isocyanate groups below 100°C, provided that at least on of these groups is an alkoxy group, Y represents a linear or branched alkylene group containing 1 to 8 carbon atoms, R represents the residue obtained by removing the isocyanate groups from a monoisocyanate or a polyisocyanate, R1 and R2 are identical or different and represent organic groups which are inert to isocyanate gropus at a temperature of 100°C or less, R3 and R4 are identical or different and represent hydrogen or organic groups which are inert to isocyanate groups at a temperature of 100°C or less, and n has a value of 1 to6. The present invention also relates to substrates coated with these coating compositions, in particular metal substrates.
