abstract |
The present invention is a polyisocyanate composition comprising a forming component having an isocyanate group, wherein the isocyanate group has reacted with at least one CH-acidic compound to an extent of 98% or more, wherein the forming component is about 51% by weight or more. Up to at least one polymethylene based on pentamethylene 1,5-diisocyanate having a content of isocyanurate trimer of not more than 60 area%, based on the total weight of the polyisocyanate based on pentamethylene 1,5-diisocyanate It relates to a composition comprising an isocyanate, the remaining proportion of which up to 100% by weight of the total amount of polyisocyanate present in the forming component comprises at least one aliphatic or cycloaliphatic polyisocyanate. The present invention further provides a one-component system comprising a polyisocyanate composition, a method for producing a coating on a substrate, and a coating obtained from the one-component system. |
