Aldehyde Comprising Compounds Suitable for Making Curable Polyisocyanate Compositions

摘要

A curable polyisocyanate composition comprising at least one or more polyisocyanate compounds, at least one or more trimerization catalyst compounds, at least one or more aldehyde compounds wherein the aldehyde compound is selected from compounds with the structure R—CHO wherein CHO is an aldehyde group and R is a hydrocarbyl group selected from an alkyl, alkenyl or aryl having 1-50 carbon atoms, preferably 1-20 carbon atoms, and at least one or more compounds selected from compounds which comprise a carboxamide group having the structure —CO—NH2 and/or from compounds which comprise a group having the structure —CO—NH—CO—.

1. A curable polyisocyanate composition comprising:
at least one or more polyisocyanate compounds, at least one or more trimerization catalyst compounds, at least one or more aldehyde compounds wherein the aldehyde compound is selected from compounds with the structure R—CHO wherein CHO is an aldehyde group and R is a hydrocarbyl group selected from an alkyl, alkenyl or aryl having 1-50 carbon atoms, preferably 1-20 carbon atoms, and at least one or more compounds selected from compounds which comprise a carboxamide group having the structure —CO—NH2 and/or from compounds which comprise a group having the structure —CO—NH—CO— wherein the number of equivalents of compounds which comprise a carboxamide group having the structure —CO—NH2 and/or from compounds which comprise a group having the structure —CO—NH—CO— is smaller or equal than the number of aldehyde equivalents and wherein the number of equivalents of compounds which comprise a carboxamide group having the structure —CO—NH2 and/or compounds which comprise a group having the structure —CO—NH—CO in the curable polyisocyanate composition over the number of trimerization catalyst equivalents is higher than 0.75.
