Abstract:
1. A coating composition comprising: (A) 100 weight parts of (i) at least one compound containing at least one acrylate group or (ii) at least one compound containing at least one isocyanate group; (B) 3-300 weight parts of at least one aminofunctional silicone resin comprising the units: wherein R is independently an alkyl group, an aryl group, or an aminofunctional hydrocarbon group, a has a value of less than 0.4, b has a value of zero or greater than zero, c has a value of greater than zero to 0.7, d has a value of less than 0.3, the value of a+b+c+d=1, with the provisos that 3 to 50 mole percent of silicon atoms contain aminofunctional hydrocarbon groups in units (i), (ii) or (iii), the —NH— equivalent weight of the aminofunctional silicone resin is from 100 to 1500, the aminofunctional silicone resin is in the form of a neat liquid, solution, or meltable solid, greater than 20 weight percent of unit (ii) is present in the aminofunctional silicone resin, less than 10 weight percent of unit (ii) are Me 2 SiO 2/2 units in the aminofunctional silicone resin, and greater than 50 weight percent of silicon-bonded R groups are silicon-bonded aryl groups, and at least 30 weight percent of all silicon atoms contain an aryl group; (C) up to 300 weight parts of at least one organic hardener; and (D) up to 5 weight parts of at least one cure rate modifier.
