The formulations can include other components such as water soluble solvents. These solvents may facilitate the solubilization of the RF-surfactants and other surfactants. These solvents can also act as foam stabilizers and/or freeze protection agents. Exemplary solvents can include ethylene glycol, diethylene glycol, glycerol, ethyl Cellusolve®, butyl Carbitol®, Dowanol DPM®, Dowanol TPM®, Dowanol PTB®, propylene glycol, and/or hexylene glycol. Additional components to the formulation, such as polymeric stabilizers and thickeners, can be incorporated into the formulation to enhance the foam stability property of a foam produced from aeration of the aqueous solution of the formulation. Exemplary polymeric stabilizers and thickeners include partially hydrolyzed protein, starches, polyvinyl resins such as polyvinyl alcohol, polyacrylamides, carboxyvinyl polymers, and/or poly(oxyethylene)glycol. Polysaccharide resins, such as xanthan gum, can be included in the formulation as a foam stabilizer in formulations for use in preventing or extinguishing polar solvent combustion, such as alcohol, ketone, and/or ether combustion, for example. The formulation can also include a buffer to regulate the pH of the formulation, for example, tris(2-hydroxyethyl) amine or sodium acetate, and a corrosion inhibitor such as toluoltriazole or sodium nitrite may be included. Water soluble electrolytes such as magnesium sulphate may be included and can improve film-spreading characteristics of the formulation.
For example and by way of example only, the following formulations can be prepared using RF-surfactants.
The RF-surfactants can also be useful in formulations that include other surfactants such as alkyl sulfate, alkylethersulfates, alphaolefinsulfonates, alkyl sulfobetaines, alkyl polyglycerides, alkylamidopropylbetaines, alkylimidazolinedicarboxylates, 2-alkylthiopropionamido-2 methyl-propanesulfonoic acid sodium salt, alkyliminodipropinates, alkylsulfonates, ethoxylated alkylphenols, dialkylsulfosuccinates, and/or alkyltrimethyl ammonium chloride.
A variation of AFFF, ARAFFF, an acronym for Alcohol Resistant Aqueous Film Forming Foam(s), can be used to extinguish hydrocarbon fires in much the same manner that AFFF foams are used and may also be used to extinguish fires involving water soluble solvents such as acetone and isopropanol which conventional AFFF foams will not extinguish.
ARAFFF formulations can contain the same ingredients as conventional AFFF formulations plus a polysaccharide such as xanthan gum and, in some formulations, a polymeric foam stabilizer. Polymeric foam stabilizers are offered by DuPont® and Dynax®, Inc. An exemplary DuPont product, Forafac® 1268, is a water soluble acrylic polymer. An exemplary Dynax product, DX5011®, is an ethyleneimine polymer. Xanthan gum is offered by several suppliers, including Kelco CP (Kelzan) and Rhodia North America (Rhodopol).
Polysaccharide alone can be sufficient to make ARAFFF formulations alcohol resistant, but the amount required produces a foam concentrate that can be quite viscous. The use of a polymeric foam stabilizer can permit a reduction in the amount of polysaccharide required to give useful alcohol resistance.
Because of the possibility of microbial attack on polysaccharide solutions, ARAFFF concentrates can contain an effective amount of a biocide such as Kathon CG ICP, manufactured by Rohm & Haas. Many other biocides such as Acticide, Nipacide and Dowicil can also be effective.
Some ARAFFF formulations can be designed to be proportioned at different percentages depending on whether the substrate to be extinguished is a hydrocarbon or an alcohol type substrate, for example. Alcohol type can include any fuel having a hydroxyl group.

For example and by way of example only, solutions of RF-monomers can be provided to a substrate and allowed to complex, for example, via evaporating the solvent of the solution to form a complex that includes a RF-monomer unit. Providing these solutions to a substrate such as glass, nylon, and/or cotton and allowing the RF-monomer to become part of a complex, such as coating the substrate.
The surface energy of the complex can be determined using the standard Fowkes method using diiodomethane and water as probe liquids, and the Zisman method of surface energy analysis using octane, decane, tetradecane, and hexadecane as probe liquids. Contact angle of drops of Zisman probe liquids, as well as, the Fowkes probes can be determined, using a Kruss prop Shape Analysis System. Surface energy data of complexes that include RF-QP monomer units are recited in the following Tables 40-42.
RF-monomers can be incorporated with other monomers and then incorporated into the construction of paper materials or used to treat paper materials. RF-monomers can also be used to prepare polymer solutions. Polymeric solutions can be diluted to a percentage aqueous or non-aqueous solution and then applied to substrates to be treated, such as paper plates.
RF-monomers can also be incorporated Into copolymers with comonomers such as the dialkyl amino alkyl acrylate or methacrylate or acrylamide or methacrylamide monomer and its amine salt quaternary ammonium or amine oxide form, as described in U.S. Pat. No. 4,147,851, herein incorporated by reference. The general formula for RF-monomers can be RFqO2CC(R)═CH2, with R being H or CH3, q being an alkylene of 1 to 15 carbon atoms, hydroxyalkylene of 3 to 15 carbon atoms, or CnH2n(OCqH2q)m—, —SO2NR1(CnH2n)—, or —CONR1(CnH2n)—, n is 1 to 15, q is 2 to 4, and m is 1 to 15. Monomers used to form copolymers with acrylates and the RF-monomers include those having amine functionality. These copolymers can be diluted in a solution and applied or incorporated directly into or on substrates to be treated, such as paper.
RF-monomers can also be used to form acrylate polymers or other acrylate monomers consistent with those described in U.S. Pat. No. 4,366,299, herein incorporated by reference. As described, RF-monomers can be incorporated into paper products or applied thereon.
RF-monomers, acrylates and/or acrylics, for example, can be applied to finished carpet or incorporated into the finished carpet fiber before it is woven into carpet. RF-monomers can be applied to carpet by a normal textile finishing process known as padding, in which the carpet is passed through a bath containing the RF-monomer and, for example, latex, water, and/or other additives such as non-rewetting surfaces. The carpet can then be passed through nip rollers to control the rate of the add-on before being dried in a tenter frame.
RF-monomers may also be incorporated into the fiber by reacting the fiber with RF-intermediates having isocyanate functionality, RF-isocyanate, for example.
RF portions can also be incorporated into materials used to treat calcitic and/or siliceous particulate materials. For example, RF-monomers can be incorporated into a copolymer where the copolymer can either be part of a formulation to treat these materials or used by itself to treat these materials as described in U.S. Pat. No. 6,383,569, herein incorporated by reference. The RF-monomer can have the general formula RF-Q-A-C(O)—C(R)═CH2 wherein RF is described above, R is H or CH3, A is O, S, or N(R1), wherein R1 is H or an alkyl of from 1 to 4 carbon atoms, Q is alkylene of 1 to about 15 carbon atoms, hydroxyalkylene of 3 to about 15 carbon atoms, —(CnH2n)(OCqH2q)m—, —SO2—NR1(CnH2n)—, or —CONR1(CnH2n)—, wherein R1 is H or an alkyl of 1 to 4 carbon atoms, n is 1 to 15, q is 2 to 4, and m is 1 to 15.
RF-compositions and mixtures containing the RF portion can be used to treat substrates including hard surfaces like construction materials such as brick, stone, wood, concrete, ceramics, tile, glass, stucco, gypsum, drywall, particle board, and chipboard. These compositions and mixtures can be used alone or in combination with penetration assistance such as non-ionic surfactants. These compositions can be applied to the surface of calcitic and/or siliceous architectural construction material by known methods, for example, by soaking, impregnation, emersion, brushing, rolling, or spraying. The compositions can be applied to the surface to be protected by spraying. Suitable spraying equipment is commercially available. Spraying with a compressed air sprayer is an exemplary method of application to the particular substrate. U.S. Pat. Nos. 6,197,382 and 5,674,961 also describe methods for applying and using polymer solutions and are herein incorporated by reference.

No. 4,478,975, herein incorporated by reference. Components of these solutions can also include dimethyl amino ethyl methacrylate, and these components can be applied in organic and inorganic solvents, as described in U.S. Pat. No. 6,120,892 herein incorporated by reference. RF-monomers can also be combined with other monomers to produce copolymers or in solutions with amido and sulfur monomers as described by U.S. Pat. No. 5,629,372 herein incorporated by reference.

According to exemplary embodiments the RF portion of the urethane can at least partially include an RF(RT)n portion as described above. The RF(RT)n portion of the urethane can also include the RS portion described above. In accordance with exemplary implementations the RS portion can be incorporated to provide additional carbon between the RF and/or RF(RT)n portions and the QU portion of the urethane. Exemplary RS portions include —CH2—CH2—. Exemplary RF-urethanes, such as RF-QU, can include, but are not limited to those listed in Table 39 below.
