Abstract:
Compositions as coatings or additives for detergent and polishing compositions having a long shelf life comprising at least0.1-30% by weight of a polytetrafluoroethylene or tetrafluoroethylene copolymers with other ethylenically unsaturated, totally or partially fluorinated, monomers;50-99% by weight of fluorinated liquid selected between perfluoropolyethers having fluoroalkylic end groups, optionally containing one chlorine and/or H atom, said perfluoropolyethers having number average molecular weights between 250 and 5,000, or liquid perfluorocarbons and mixtures thereof optionally containing heteroatoms such as oxygen and nitrogen, having a number of carbon atoms comprised between 5 and 18;polar solvent complement to 100% by weight;0.01-5% by weight of surfactant selected from:(a) nonionic hydrogenated or(b) fluorinated, having a perfluoropolyether or perfluoroalkylic chain, both of ionic and nonionic type, selected from the following classes:A') mono and dicarboxylic acid salts;B') sulphonic acid salts;C') phosphoric mono- and deters and their mixtures, as such or salified, optionally containing amounts of triesters lower than 15% by moles;D') nonionic surfactants formed by fluorinated and polyoxyalkylenic chains with a number of oxyalkylenic repeating units higher than 6; andE') cationic surfactants having one or more fluorinated hydrophobic chains.
