Fire Protection Industry
High-efficiency fluoroprotein fire extinguishing agent: Add OBS-isopropanol-water solution (ratio ~4:3:3) to foam liquid to make high-concentration fluoroprotein foam fire extinguishing agent (containing ~0.108% OBS). It can also be mixed with hydrocarbon surfactants such as sodium alkylbenzene sulfonate, sodium alkylnaphthalene sulfonate, and sodium fatty alcohol sulfate. Due to the excellent surface properties of fluorosurfactants, the stable foam spreads on the oil surface, and the fire-extinguishing speed is 3-4 times that of ordinary protein fire extinguishing agents. Adding OBS to ordinary fluoroprotein fire extinguishing agents produces fluoroprotein anti-solvent foam fire extinguishing agents, which significantly improve the liquid resistance and heat resistance of the foam, suitable for extinguishing fires of water-soluble liquids such as alcohols and esters.

Petroleum Exploitation
Used in secondary and tertiary oil recovery, it is one of the main raw materials for oil recovery cleanup additives. It can reduce the surface tension of fracturing fluid and oil-water interfacial tension, with advantages such as cleanup and drag reduction, and high-efficiency foaming cleanup. OBS has stronger surface activity, which can reduce the oil-water interfacial tension between crude oil and the flooding system, making crude oil separate from rock formations and sediment, forming an oil-in-water system to be pressed to the surface, improving oil recovery efficiency and output. OBS can be well compounded with ordinary hydrocarbon surfactants, reducing costs and improving benefits, with a general dosage of about 0.3%.
-
Steel Plate Cleaning
Adding an appropriate amount of OBS to water-based cleaning agents for steel plate storage can significantly enhance decontamination ability, improve work efficiency, and not easily damage the rust-proof performance of steel plates.
-
Photosensitive Film
As an antistatic agent mixed in some solutions and coated on film substrates, it solves the problem of electrostatic sparks caused by high-speed rotational friction in film production, ensuring product quality. It also enhances the dispersion speed and effect of other components on the substrate.
-
Printing
Ordinary inks often have defects such as discoloration, broken lines, and color stacking when printing on plastic films and treated smooth paper. OBS (generally 0.01%-0.1%) can significantly improve the leveling, adhesion and gloss of the ink. For example, adding OBS to the ink can reduce ink stacking and ghosting, improve ink wettability; or compounded with transparent yellow pigments, it can improve pigment wettability, enhance ink colorability, and solve printing failure problems.

Other Uses
-
Continuous paper: Adding OBS surfactants to the paraffin-rosin-water system can prepare paraffin-rosin-water dispersions with high coverage and good stability.
-
Electroplating: Keeping the surface of plated parts clean is a prerequisite for high-quality electroplating layers. Adding about 0.3% OBS to the bright plating solution for copper products can obtain satisfactory brightening effects and reduce plating solution fog.
-
Inks and coatings: Adding OBS (as a dispersant) to the concentrated dispersion of tetrafluoroethylene or fluoroplastics (FEP) can improve the wettability and spreadability of the dispersion, allowing it to obtain a thicker metal surface coating.
