TEXTURED POLYURETHANE SURFACE |
摘要 |
<p>TEXTURED POLYURETHANE SURFACE A textured polyurethane surface is created from a vinyl substrate by first forming a smooth, uncured polyurethane coating on the substrate and then heating the thus coated substrate to a temperature between about 100.degree. and about 160.degree.C for 1 to 10 minutes followed by heating to temperatures of 170.degree. to 210.degree.C for 0.5 to 10 minutes. A textured surface may also be provided on a vinyl substrate having a previously cured polyurethane coating thereon by waiting at least about 1 week after the urethane coating has been cured and then heating the coated substrate to a temperature between about 140.degree.C and about 210.degree.C for 0.1 to 10 minutes. A preferred application is in the creation of textured surfaces on sheet vinyl floor and wall coverings coated with polyurethane.</p> |
