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.

Abstract: A compound has at least three functionalities, including a first functionality (a) that is a sulfonate group or a sulfate group of the formula —(O)d—SO3M with d=0 or 1 and with M=hydrogen or a monovalent metal cation or a corresponding portion of a multivalent metal cation; a second functionality (b) that is a (meth)acryl residue; and a third functionality (c) that is a carboxylic acid function and/or a thioether group. When the compound is free of silicon, the sulfonate or sulfate group and the (meth)acryl residue are separated from each other by a hydrocarbon-containing residue having a carbon chain. The carbon chain is interrupted by S or NH, or the carbon chain contains a linking group, selected from C(O)NH, NHC(O), NR8C(O), NHC(O)O, NR8C(O)O, NHC(O)NH, C(O)NHC(O) and —C(O)S—, wherein R8 is alkyl or alkenyl or a (meth)acryl group.

Abstract: A silane of the formula (I) containing at least one aliphatic amidine group- or guanidine group-containing alkoxy group, to a method for producing same, to conversion products thereof, and to the use thereof as a catalyst in curable compositions, in particular based on silane group-containing polymers. The silane of the formula (I) is largely odorless and non-volatile at room temperature. The silane accelerates the hydrolysis and condensation reaction of silane groups very effectively without impairing the storage stability of silane group-containing polymers. Additionally, the silane is very tolerable in silane group-containing compositions, whereby such compositions are not prone to separate, migrate, or evaporate the catalyst.
