Fluorinated surfactants have an irreplaceable role in many fields because of their unique properties of high surface activity, good heat resistance, strong chemical stability and water and oil repellency. However, their high production cost, poor solubility and low temperature resistance limit their application to some extent. As a special type of surfactant, silicon-containing surfactants have […]

Antimicrobial coatings are an important development in the coatings industry today. Adding the right amount of antimicrobial agent to the coating formulation can play an effective antibacterial or antimicrobial role. Especially with the emergence of the new coronavirus in the past few years, there is a growing interest in antimicrobial coatings. In addition to some

Surfactants can change (usually reduce) the interfacial tension between two phases, and are amphiphilic compounds composed of hydrophilic and lipophilic groups, with the lipophilic (hydrophobic) groups consisting of hydrocarbon chains and the hydrophilic groups consisting of oxygen-containing groups such as hydroxyl, carboxyl and ether groups. Therefore, the properties of surfactants not only depend on the

A, with antifreeze function water freezing point is 0 ° C, the freezing point of antifreeze can generally be lower than -25 ° C. In the cold winter parking, to prevent the coolant from freezing and cracking the radiator and freezing engine block. Second, the boiling point of antifreeze is higher than that of water,

Silicone oil is a widely used conditioning agent in shampoos. Polysiloxanes with different polymerization degrees and chain structures are structurally stable and have strong conditioning, lipid-attached, moisturizing, smoothing and shining effects. When shampooing, the surfactant will wash off the excess grease, which will cause dry scalp, dry hair easy to knot, not easy to comb,
