Abstract
Official abstract text for this publication.
A polyisocyanate composition contains a modified product of xylylene diisocyanate and a modified product of pentamethylene diisocyanate, and/or a modified product of the xylylene diisocyanate and the pentamethylene diisocyanate. The ratio of the pentamethylene diisocyanate with respect to the total amount of the xylylene diisocyanate and the pentamethylene diisocyanate is 5 mol % or more and 40 mol % or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyisocyanate composition containing: a modified product of xylylene diisocyanate and a modified product of pentamethylene diisocyanate, and/or a modified product of the xylylene diisocyanate and the pentamethylene diisocyanate, the ratio of the pentamethylene diisocyanate with respect to the total amount of the xylylene diisocyanate and the pentamethylene diisocyanate is 5 mol % or more and 40 mol % or less, the modified product of the xylylene diisocyanate contains a trimer, in the modified product of the xylylene diisocyanate, the trimer conversion rate of the xylylene diisocyanate is 5 mass % or more and 45 mass % or less, the modified product of the xylylene diisocyanate is modified with at least alcohols, and an alcohol rate with respect to the total amount of the modified product of the xylylene diisocyanate is 0.1 mass % or more and 10 mass % or less. 2. A polyurethane resin obtained from reaction of the polyisocyanate composition according to claim 1 with an active hydrogen group-containing compound. 3. A two-component curable polyurethane composition containing a polyisocyanate component containing the polyisocyanate composition according to claim 1 , and a polyol component. 4. A coating material obtained from the two-component curable polyurethane composition according to claim 3 .
