  • Patent number: 6255398
    Abstract: The invention provides thermosetting coating compositions in which acrylic copolymers are used as carriers for fluorocarbon resins. The compositions have a combination of high fluorocarbon content, high solids content, and a low viscosity suitable for coil coating. Thus, the solids are borne in organic solvent systems which permit minimization of the viscosity and a moderate evaporation rate. The solvent system has a &dgr;H of from 1.7 to 2.6 (calories/cubic centimeter)½ and a &dgr;V of from 8 to 9.5 (calories/cubic centimeter)½ and is exemplified by a mixture of 4 or more of the following solvents: aliphatic ketones having from 4 to 10 carbon atoms, alkyl esters having a total of from 5 to 7 carbon atoms, aromatic acid esters having from 8 to 12 carbon atoms, lactones, and aromatic solvents.

  • Patent number: 6255514
    Abstract: In an extraction process for isolating trimethoxysilane (TMS) from a TMS/methanol mixture by formation of two phases, namely a TMS-rich extract phase and a methanol-rich raffinate phase, by addition of one or more methanol-soluble inorganic and/or organic salts and, if desired, an additional nonpolar organic solvent and subsequent phase separation, the amount of salt added is selected so that the weight ratio of trimethoxysilane to methanol in the extract phase is at least 94% by weight:6% by weight (normalized to 100% by weight). The use of one or more inorganic salts in an extraction process for isolating trimethoxysilane from a trimethoxysilane/methanol mixture is also claimed.
