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 30 mol % or more and 80 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, and the ratio of the pentamethylene diisocyanate with respect to the total amount of the xylylene diisocyanate and the pentamethylene diisocyanate is 30 mol % or more and 60 mol % or less. 2. The polyisocyanate composition according to claim 1 , wherein in chromatogram of the polyisocyanate composition in gel permeation chromatograph measurement, the ratio of the peak area having a peak top between polyethylene oxide-based molecular weight of 300 to 800 relative to a total peak area is 50% or more and 95% or less. 3. The polyisocyanate composition according to claim 1 , wherein the modified product of the pentamethylene diisocyanate is modified with at least alcohols, and an alcohol rate with respect to the total amount of the modified product of the pentamethylene diisocyanate is 0.1 mass % or more and 30 mass % or less. 4. The polyisocyanate composition according to claim 1 , wherein the modified product contains at least one functional group selected from the group consisting of the following (a) to (i): (a) isocyanurate group, (b) allophanate group, (c) biuret group, (d) urethane group, (e) urea group, (f) uretdione group, (g) iminooxadiazinedione group, (h) uretonimine group, and (i) carbodiimide group. 5. A polyurethane resin obtained from reaction of the polyisocyanate composition according to claim 1 with an active hydrogen group-containing compound. 6. A two-component curable polyurethane composition containing a polyisocyanate component containing the polyisocyanate composition according to claim 1 , and a polyol component. 7. A coating material obtained from the two-component curable polyurethane composition according to claim 6 . 8. An adhesive material obtained from the two-component curable polyurethane composition according to claim 6 .
