Abstract
Disclosed is a highly fluorinated silicone resin and a method for making the same. The silicone resin includes M, T, optionally D and optionally Q type monomers and is crosslinkable. The resin has a fluorine content of at least 55 weight percent and a very low refractive index of less than 1.4. The resin is formed in a one step process and requires use of very specific solvents. Preferably the resin includes a first T type monomer having a fluoroalkane group to provide the fluorine to the resin. Preferably the resin includes a second T type monomer having a (meth)acryloyl function to enable cross-linking. The resin forms an effective liquid optically clear adhesive. The resin can be further combined with highly fluorinated (meth)acrylate monomers or perfluoro polyethers to provide even lower refractive indexes and improved adhesive properties.
