ABSTRACT:
A process for the production of polyisocyanates containing isocyanurate groups by the catalytic trimerization of a mixture of low molecular weight isocyanate components having aliphatically and aromatically bound isocyanate groups in the presence of aminosilyl compounds, the resulting polyisocyanates and their use in coating compositions.
