A composition of formula I[Rf(CH)(O)]-Awherein

Fluorinated surfactants

A surfactant of formula 1(R-A)-Q-([B]&#x2014;R)&#x2003;&#x2003;Formula 1wherein

Mixed fluoroalkyl-alkyl surfactants

The invention provides a non-stick coating for glass cookware that has good adhesion and stain resistance while maintaining the abrasion resistance of the non-stick coating. The non-stick coating comprises a base coat that contains fluoropolymer and colloidal silica and an overcoat comprising one or more polymer layers containing inorganic filler film hardener.

Glass articles with adhesion and stain resistant non-stick coatings

A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorinated urethane additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.

Method for achieving recoat adhesion over a fluorinated topcoat

A composition of formula I[Rf(CH2)m(O)n]x-Awherein

A coating composition containing a film-forming organosilane polymer, optionally a non-aqueous dispersed polymer, and a crosslinking agent selected from one or both of an organic polyisocyanate and melamine crosslinker. Fluorine functionalities are incorporated in the organosilane polymer to enhance soil resistance and cleanability. The coating composition can be used as a clearcoat over a conventional pigmented basecoat. The coating composition provides improved soil resistance and cleanability.

Coating compositions containing a fluorinated organosilane polymer

A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorourethane star polyester additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.

A composition providing stain resistance to stone, masonry and other surfaces is provided comprising a mixture of a fluoroalkyl phosphate and a fluoroacrylate polymer.

Stain resistant compositions

Fluorinated vinyl ethers having phosphorus-containing groups are useful as monomers in making fluoropolymers having functional sites.

Phosphorus-containing fluoromonomers and polymers thereof

This invention relates to a process for the preparation of an inorganic oxide gel comprising contacting at least one fluorinated inorganic oxide precursor with a fluorinated gelling agent in the presence of at least one fluorinated solvent to form a solution; allowing sufficient time for gelation to occur; and isolating the inorganic oxide gel. Gels made by this process are useful as coatings and as components in inorganic/organic hybrid materials.

Process for making inorganic oxide gels in fluorocarbon solvents

The present invention pertains to molecular and oligomeric organo-silicon compounds bearing fluorine atoms, soluble in fluorinated solvents and useful as precursors to network materials.

Molecular and oligomeric silane precursors to network materials

This invention relates to a fluoropolymer nanocomposite comprising a fluoropolymer phase and an inorganic oxide phase dispersed throughout, said inorganic oxide phase having either no particles or particles substantially all of which have a particle size of less than about 75 nm which can be determined by small angle x-ray scattering and transmission electron microscopy techniques. These nanocomposites are useful as protective coatings.
