20080264864 | PROCESS FOR REMOVING FLUORINATED EMULSIFIER FROM FLUOROPOLMER DISPERSIONS USING AN ANION-EXCHANGE RESIN AND A pH-DEPENDENT SURFACTANT AND FLUOROPOLYMER DISPERSIONS CONTAINING A pH-DEPENDENT SURFACTANT - A process of reducing the amount of fluorinated emulsifiers in fluoropolymer dispersions by contacting the fluoropolymer dispersion with an anion exchange resin in the presence of a pH-dependent surfactant, and fluoropolymer dispersions containing the pH-dependent surfactant and uses thereof. | 10-30-2008 |
20080287599 | FLUOROPOLYMER DISPERSION CONTAINING NO OR LITTLE LOW MOLECULAR WEIGHT FLUORINATED SURFACTANT - The present invention provides a fluoropolymer dispersion comprising fluoropolymer particles having an average particle size of 10 to 400 nm dispersed in water whereby the dispersion is free of fluorinated surfactant having a molecular weight of less than 1000 g/mol or contains the fluorinated surfactant having a molecular weight of less than 1000 g/mol in an amount of not more than 0.025% by weight based on the total weight of solids in the dispersion. The dispersion further comprises a non-ionic surfactant and an anionic surfactant selected from fluorinated anionic surfactants having a molecular weight of at least 1000 g/mol, non-fluorinated anionic surfactants and mixtures thereof. | 11-20-2008 |
20090192260 | PROCESS FOR REMOVING FLUORINATED EMULSIFIER FROM FLUOROPOLMER DISPERSIONS USING AN ANION-EXCHANGE RESIN AND A pH-DEPENDENT SURFACTANT AND FLUOROPOLYMER DISPERSIONS CONTAINING A pH-DEPENDENT SURFACTANT - A process of reducing the amount of fluorinated emulsifiers in fluoropolymer dispersions by contacting the fluoropolymer dispersion with an anion exchange resin in the presence of a pH-dependent surfactant, and fluoropolymer dispersions containing the pH-dependent surfactant and uses thereof. | 07-30-2009 |
20100047585 | PROCESS FOR REMOVING FLUORINATED EMULSIFIER FROM FLUOROPOLYMER DISPERSIONS USING AN ION-EXCHANGE RESIN AND DISPERSIONS OBTAINED THEREFROM - The present invention provides a process for reducing the amount of fluorinated emulsifier in fluoropolymer dispersions by contacting the fluoropolymer dispersion with an anion exchange resin in the presence of amphoteric surfactants or anionic surfactants of low molecular weight and provides fluoropolymer dispersions containing low amounts of fluorinated emulsifier and no or only low amounts of non-ionic surfactants. | 02-25-2010 |
20100113679 | METHOD OF MAKING FLUOROPOLYMER DISPERSION - A method of making a fluoropolymer dispersion by first providing a fluoropolymer dispersion comprising fluoropolymer particles and one or more fluorinated surfactants selected from fluorinated carboxylic acids or salts thereof having the general formula: | 05-06-2010 |
20120129982 | FLUOROPOLYMER COMPOSITIONS CONTAINING A POLYOL COMPOUND AND METHODS OF MAKING THEM - There are provided compositions comprising (i) at least one non-aromatic polyol compound containing at least one polyol unit having at least two hydroxyl groups and at least one long chain unit containing at least 6 carbon atoms; and (ii) at least one fluoropolymer comprising repeating units derived from a fluorinated olefin. There are also provided methods of improving the shear stability of fluoropolymer dispersions, methods of coating substrates, and substrates coated with the above described composition. | 05-24-2012 |
20120252949 | METHOD OF MAKING FLUOROPOLYMER DISPERSION - A method of making a fluoropolymer dispersion by first providing a fluoropolymer dispersion comprising fluoropolymer particles and one or more fluorinated surfactants selected from fluorinated carboxylic acids or salts thereof having the general formula: | 10-04-2012 |
20130344341 | FLUOROPOLYMER COATED ARTICLES - Provided is an article comprising a bearing, wherein the bearing has disposed upon it a fluoropolymer composition. The fluoropolymer composition comprises a fluoropolymer and a pH-dependent surfactant. | 12-26-2013 |
