FLEXIBLE COATING COMPOSITIONS HAVING IMPROVED SCRATCH RESISTANCE, COATED SUBSTRATES AND METHODS RELATED THERETO

摘要

PROBLEM TO BE SOLVED: To provide coating compositions which are both flexible and resistant to scratching. SOLUTION: Coating compositions are provided which are formed from components comprising (a) at least one polysiloxane, (b) at least one polyol, and (c) at least one reactant comprising at least one functional group that is reactive with at least one functional group selected from the at least one reactive functional group of the at least one polysiloxane (a) and at least one functional group of at least one polyol (b), wherein each component is different. The coating which is formed from the coating compositions has at least six flexible marks according to a flexible examination method at 70°F when cured. COPYRIGHT: (C)2006,JPO&NCIPI
