Abstract
Novel fluorosilicone hydrides are provided which are useful as intermediates in the preparation of epoxy-functional fluorosilicones having improved cure efficiency at low temperatures and improved resistance to solvents and fuels than analogous non-fluoro-functional epoxy-functional silicones prepared from non-fluoro-functional silicone hydrides.
