Abstract
Official abstract text for this publication.
The present invention provides a polyisocyanate composition wherein the composition is obtained from an aliphatic diisocyanate unit including 1,6-diisocyanatohexane, and has an isocyanurate group, a uretdione group, a uretonimine group, and an iminooxadiazinedione group, and the molar ratio of the uretonimine group to the isocyanurate group is 0.0010 to 0.0050, and the molar ratio of the iminooxadiazinedione group to the isocyanurate group is 0.00050 to 0.30.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyisocyanate composition wherein the composition is obtained from an aliphatic diisocyanate unit including 1,6-diisocyanatohexane, and has an isocyanurate group, a uretdione group, a uretonimine group, and an iminooxadiazinedione group, and the molar ratio of the uretonimine group to the isocyanurate group is 0.0010 to 0.0050, and the molar ratio of the iminooxadiazinedione group to the isocyanurate group is 0.00050 to 0.30. 2. The polyisocyanate composition according to claim 1 further comprising an isocyanurate.uretdione bonded tetramer represented by following formula (I): 3. A coating composition comprising the polyisocyanate composition according to claim 1 , and an acrylic polyol and/or a polyester polyol. 4. A method for producing a coating film comprising a step of curing the coating composition according to claim 3 . 5. A coating composition comprising the polyisocyanate composition according to claim 2 , and an acrylic polyol and/or a polyester polyol. 6. A method for producing a coating film comprising a step of curing the coating composition according to claim 5 .
