AQUEOUS POLYURETHANE COATING COMPOSITIONS |
| 摘要 |
An aqueous coating composition comprising a crosslinkable water-dispersible polyurethane oligomer wherein said composition when drying to form a coating has an open time of at least 20 minutes, a wet-edge time of at least 10 minutes, a tack free time of <20 hours and an equilibrium viscosity of <5,000 Pa.s at a solids content when drying in the range of from 20 to 55 wt % using a shear rate in the range of from 9±0.5 to 90±5 s<SUP>-1 </SUP>and at 23+2° C. |
