One-Part Moisture-Curable Polyurethane Composition |
| 摘要 |
A one-part moisture-curable polyurethane composition according to the present technology comprises: a urethane prepolymer (A), a crosslinking agent (B), carbon black (C) and a catalyst (D). The crosslinking agent (B) is at least one type selected from the group consisting of isocyanurate of hexamethylene diisocyanate (b1), allophanate of hexamethylene diisocyanate (b2), a reaction product of hexamethylene diisocyanate with trimethylolpropane (b3), and a reaction product of hexamethylene diisocyanate with glycerin (b4). The content of the crosslinking agent (B) is from 8 to 20 parts by mass per 100 parts by mass of the urethane prepolymer (A). |
