Low-foam penetrant SF is widely used in multiple industries such as textile printing and dyeing, industrial cleaning, paper deinking, leather processing, and pesticide synergism. It is a multifunctional nonionic surfactant with both low foaming and rapid penetrating properties.

Detailed Explanation

Low-foam penetrant SF (fatty alcohol polyoxyethylene ether phosphate ester) leverages its unique molecular structure to achieve extremely low foam performance while maintaining fast and deep penetration. Its nonionic nature, combined with partial anionic characteristics, provides excellent chemical stability in acidic, alkaline, and hard water environments, making it suitable for various pH conditions in processing. It is a key functional additive in numerous industrial processing and cleaning applications.

In the textile industry, this product is used throughout the entire process from pretreatment to dyeing, ensuring efficient and uniform treatment. In industrial cleaning, its low-foam property is particularly suitable for high-pressure spraying and CIP online cleaning systems, effectively avoiding production interruptions and equipment damage caused by foam overflow. Additionally, it demonstrates significant synergistic value in traditional industries like papermaking and leather, as well as emerging applications such as agrochemical formulations.

Application Fields and Processes

Industry Field Specific Process/Application Function and Effect
Textile Industry Desizing, scouring, bleaching, dyeing and other pretreatment and processing of cotton, linen, chemical fibers and their blends Ensures chemicals uniformly and quickly penetrate the fiber interior, enhancing treatment effect and levelness, effectively shortening processing time
Industrial and Hard Surface Cleaning Metal parts cleaning, food processing equipment cleaning, high-pressure spray cleaning, CIP online cleaning systems Rapidly wets and penetrates dirt layers under low-foam conditions, stripping and dispersing impurities, avoiding foam interference, improving cleaning efficiency
Papermaking Industry Waste paper deinking process, pulp penetration aid Promotes rapid separation of ink particles from fiber surfaces, improving deinking efficiency and pulp brightness
Leather Processing Soaking process, degreasing process Helps chemicals quickly penetrate the leather, shortening soaking time, effectively removing natural fats, preparing for subsequent tanning
Agricultural Chemicals Spray adjuvant for wettable powders, water suspensions, and other pesticide formulations Significantly reduces surface tension of spray liquid, enhancing wetting, spreading, and penetration on plant leaves and target organisms, improving pesticide utilization and control efficacy

Application Recommendations

Depending on the application scenario, the recommended dosage and usage method of low-foam penetrant SF may vary. In textile pretreatment, it is usually combined with auxiliaries such as caustic soda and hydrogen peroxide; in industrial cleaning formulations, it can synergize with nonionic or anionic surfactants; as a pesticide adjuvant, it is recommended to determine the optimal addition ratio through small-scale trials. Please adjust the specific dosage according to process conditions and actual needs.

Precautions

  • The product is not classified as a hazardous chemical, has low skin irritation, is a non-flammable liquid, and offers high safety in storage and transportation.
  • Storage temperature should be controlled between 5°C and 35°C, keep the container sealed, avoid direct sunlight, and keep away from strong oxidizers.
  • It is recommended to wear chemical safety goggles and protective gloves during operation to avoid prolonged direct contact with skin and eyes.
  • When used in dynamic circulation or high-speed jet systems, its low-foam property effectively prevents foam overflow, significantly improving operational efficiency.
