Brushing cationic surfactants mixed with oil on wood surfaces may promote the penetration of oily coatings, but the specific effect still needs to consider multiple factors.
Cationic surfactants are a type of positively charged surfactants whose molecules form micelle structures in aqueous solutions. The micelle structure of cationic surfactants may help improve the permeability of oil based coatings between wood fibers after being coated with appropriately diluted oil based coatings (such as certain paints or wood protectants) on the surface of wood.
Cationic surfactants can reduce the surface tension of liquids and make it easier for liquids to penetrate into the pores of wood. This penetration helps oily coatings better adhere to the surface of wood and provide long-lasting protection. In addition, cationic surfactants may also improve the uniformity and adhesion of the coating, making it more stable.
However, this also depends on factors such as the properties of the specific wood, the treatment of the wood surface, and the formulation of the oily coating used. Therefore, in practical applications, it is recommended to conduct experiments first to determine the compatibility between cationic surfactants and specific oily coatings on wood, and to ensure that the selected treatment method and coating formula can achieve the required penetration effect and surface quality.
In addition, when using any chemical, please refer to the product manual, follow the correct usage method, and follow local regulations.
