Abstract
The present invention relates to methods and chemical compositions utilizing NPB (n-propyl bromide) also called 1-bromopropane or propyl bromide or 1-BP or N-Bromopropane as non-aqueous carrier mediums to apply fire retardants, fluorocarbons and other chemicals to substrates, whereby the NPB is evaporated away leaving the remaining chemicals on the substrate. The present invention offers compositions and method for applying organic chemicals to substrates that perform superior to current water based technology. Additional, the invention offers a more economical and environmental friendly alternative to current chlorinated hydrocarbons carriers that are being phased out by mandate of the Environmental Protection Agency (EPA).
Claims11
Chemical formulations comprising component (A) NPB (n-propyl bromide) as a non-aqueous carrier medium to apply component (B) fluorocarbons to textile and non-woven substrates, whereby the NPB is evaporated leaving the remaining fluorocarbon on the substrate. The said fluorocarbon being selected from the group:
- polyvinylidene fluoride;
- polytetrafluoroethylene;
- perfluoroalkylethyl acrylates;
- perfluoroalkylethyl methacrylates;
- mixtures of the same;
- and
- blends of the foregoing compounds and polymers with polyalkyl acrylates, polyalkyl methacrylates, and copolymers of vinylidene chloride, vinylidene fluoride, tetrafluoroethylene, perfluoroalkylethyl acrylates, and perfluoroalkylethyl methacrylates, and wherein the said fluorocarbon is 0.002% to 4% by weight of the base weight of the substrate.
2-15. (canceled)
Chemical formulations comprising (A) NPB (n-propyl bromide), and (B) a coating component, and (C) a cross linking, extender or other component, whereas the said NPB is used as a medium to apply components (B) and (C), and whereby the NPB is evaporated away leaving the remaining (B) and (C) chemicals on a textile or non-woven substrate.
Composition for treating textile and non-woven substrates by the composition, stabilized NPB, whereby the said stabilized NPB is utilized to dissolve and remove contaminants from the said substrates.
