  • Publication number: 20080311053
    Abstract: Foaming compositions having high solvent content and compositions for foaming high solvent content formulations are disclosed having a fluorinated phosphate ester surfactant (“FPES”) of the formula (Ra—O)x—P(O)—(ORb)y in combination with a fluorinated alcohol (“FA”) of the formula RcOH, where x is 1 to 3, y is (3?x), Ra is a group R1-R2- with R1 being a fluorinated C6-18hydrocarbon optionally interrupted by groups of one or two non-fluorinated (or less fluorinated) carbons per interruption, and/or optionally interrupted by heteroatoms or functional groups, and Rb is selected from H and positively charged amines, and Rc is the same or different as Ra and if different is selected from the same group of Ra materials as well as from analogous groups to Ra except that they have only 1-3 carbons in the R1 portion of Ra instead of the Ra requirement of at least 4 carbons. The ratio of FA to FPES is at least 5% FA to not more than 95% FPES based on the total FA+FPES weight.
