METHOD OF COATING A SUBSTRATE WITH A FLUOROPOLYMER DISPERSION |
摘要 |
<p>The present invention provides a method of coating a substrate having a surface defined by a layer of fluoropolymer. The method utilizes an aqueous dispersion that includes: particles of melt-processible fluoropolymer in an amount of 30 to 70% by weight; a fluorinated surfactant in an amount of not more than 250ppm based on fluoropolymer solids of the aqueous dispersion; and a non-ionic surfactant comprising an ethoxylated aliphatic alcohol in an amount of 2 to 15% by weight based on total solids of the aqueous dispersion. The aqueous dispersion is free or substantially free of aromatic group containing non-ionic surfactants. The aqueous dispersion may be optionally diluted and/or modified with additional components to obtain a coating composition. The coating composition may then be applied on at least part of the surface of the substrate to define the fluoropolymer layer.</p> |
