Intersection markings. |
摘要 |
Pavement-marking sheet materials of increased durability comprise a tough, abrasion-resistant top layer, preferably a polyurethane film having substantial flexibility but including trifunctional hydroxyl-terminated components of short molecular weight so as to obtain a significant degree of crosslinking, and a conformable underlying layer. A preferred underlying layer comprises unvulcanized elastomer precursor. |
