Zusammenfassung:	Poliisocianato que se basa en 2,4-diisocianato de tolileno, 2,6-diisocianato de tolileno o una mezcla de 2,4- y 2,6- diisocianato de tolileno y tiene grupos isocianurato, en el que el poliisocianato tiene a) un peso molecular promedio en peso de >= 350 a 1 a 1 to < 1.5, where the polydispersity D is the ratio of weight average and number average molecular weight of the polyisocyanate and the weight average and number average molecular weight are in each case determined by means of gel permeation chromatography using a polystyrene standard and tetrahydrofuran as eluent in accordance with DIN 55672-1:2016-03, and c) a content of monomeric tolylene diisocyanate of < 1 % by weight, based on the total weight of the polyisocyanate.
