FLUOROPOLYMER AQUEOUS HYBRID COMPOSITIONS WITH IMPROVED FILM FORMATION
摘要
The invention relates to aqueous fluoropolymer hybrid compositions made by a seeded emulsion polymerization process, having improved film formation properties. The seed is a fluoropolymer dispersion. At least two different monomer compositions are added sequentially to the seeded dispersion. These monomer compositions preferably include acrylic monomers. The first monomer composition is selected for miscibility with the fluoropolymer dispersion. The second monomer composition is selected to have a glass transition temperature (Tg) of less than 30°C. The final composition can be formulated to make coatings with a minimum film forming temperature (MFFT) of less than 5°C, and a maximum VOC of 50 g/liter. The composition is especially useful for coatings and films.
