One-component burn-in system

Abstract

The invention relates to a one-component burn-in system comprising A) a blocked polyisocyanate component containing at least one reaction product of a) at least one polyisocyanate component, which has at least isocyanurate and/or iminooxadiazinedione structures, b) at least one branched aliphatic diole, and c) at least one secondary amine with aliphatic, cycloaliphatic, and/or araliphatic substituents, wherein the component b) is used in a quantity of more than 2 wt. % based on the total quantity of the components a) and b), and the component c) is used in a quantity which corresponds to at least 95 mol. % of the isocyanate groups mathematically still present after the reaction of the components a) and b), B) at least one binder which is reactive to isocyanate groups and comprises at least two isocyanate-reactive groups per molecule on statistical average, C) optionally catalysts, and D) optionally solvents and/or optionally auxiliary agents and additives.
