CURABLE FILM-FORMING COMPOSITIONS DEMONSTRATING SELF-HEALING PROPERTIES |
摘要 |
The present invention is directed to curable film-forming compositions comprising: (a) a polymeric binder comprising a polyester having hydroxyl functional groups; and (b) a curing agent comprising a polyisocyanate having at least three isocyanate functional groups. In certain embodiments, after application to a substrate as a coating and after curing, the compositions demonstrate a Fisher microhardness of at least 120 at ambient temperatures of 15 to 25°C and a softening point greater than or equal to 35°C. Additionally, in certain embodiments, after application to a substrate as a coating and after curing, the compositions demonstrate a 20° gloss recovery of at least 75% when subjected to the dry abrasion test method.
