Classical silicone resins have limited compatibility with organic resins, but some specially designed high-phenyl content silicones have good compatibility with other organic film formers. In general, organic film formers contribute to quick-drying (dry to handle) characteristics, hardness and abrasion resistance, while silicones improve weatherabi — lity and heat resistance. Commonly used organic binders for blending
with silicones are short and medium oil alkyds, polyesters, phenolics, UF-and MF-based baking finishes, low MW epoxies, and acrylics.
