Production of a Blocked Curing Agent Based on a Partly Organic-Based Polyisocyanate and Use as a 1K PUR Baking Enamel

The invention relates to a polyisocyanate composition including an isocyanate group-containing formative component, the isocyanate groups being reacted to ≥50% with at least one isocyanate group-reactive compound which includes at least one N-R1 group, R1 being selected from H or OH and N being conn...

Beschreibung
Zusammenfassung:	The invention relates to a polyisocyanate composition including an isocyanate group-containing formative component, the isocyanate groups being reacted to ≥50% with at least one isocyanate group-reactive compound which includes at least one N-R1 group, R1 being selected from H or OH and N being connected to the other atoms of the compound via two single bonds or a double bond, where the formative component is formed by up to ≥51 wt. % of at least one polyisocyanate based on 1,5-pentamethylene diisocyanate having an isocyanurate trimer content of ≤60 area. %, based on the total weight of the polyisocyanates based on 1,5-pentamethylene diisocyanate and determined by means of gel permeation chromatography in accordance with DIN 55672-1:2007-08, and the proportion, missing by up to 100 wt. %, of the total amount of polyisocyanates contained in the formative component includes or consists of at least one aliphatic or cycloaliphatic polyisocyanate.
