POLYISOCYANATE COMPOSITION HAVING ALLOPHANATE GROUP AND HIGH-SOLID COATING MATERIAL |
摘要 |
<p>A polyisocyanate composition comprising an allophanate group, which is obtained from an aliphatic diisocyanate(s), wherein in a state substantially free of a solvent and the aliphatic diisocyanate(s), (i) the content of components having a molecular weight of 700 or less is 20-60 weight %, (ii) the ratio of weight average molecular weight to number average molecular weight is 1.20-5.00, (iii) the ratio of viscosity (unit: mPa.s) of the polyisocyanate composition at 25 DEG C to the number average number of functional groups of isocyanate groups is represented by the following expression: viscosity (mPa.s)/number average number of functional groups≤240.</p> |
