The usage of low-foam penetrant SF varies by application area. The general recommended dosage is 0.1%~1.0% of the total working liquid volume. The specific dosage should be determined through experiments based on process conditions and treatment requirements.
Detailed Description
Low-foam penetrant SF is a nonionic surfactant (fatty alcohol polyoxyethylene ether phosphate ester) that also exhibits some anionic properties. Its core advantages lie in extremely low foam performance and rapid deep penetration ability, combined with excellent acid, alkali, and hard water stability. Since the product is in liquid form, it can be directly added to the working liquid and stirred evenly without the need for pre-dissolution, making operation very simple.
The usage of this product varies slightly in different application scenarios: In the textile industry, it can be directly added to desizing, scouring, bleaching, or dyeing baths to work synergistically with other auxiliaries; in industrial cleaning, it can be compounded with alkaline or acidic cleaning agents and then added to the cleaning system; in pesticide formulations, it is typically added as a synergist during the formulation process. The general principle is to avoid direct mixing with strong oxidizers, and it is recommended to add slowly under stirring conditions to ensure uniform dispersion.

Application Recommendations
Recommended Dosage (Reference Range):
- Textile pretreatment (desizing/scouring/bleaching): 0.2%~0.5% (based on working liquid weight), helps chemicals uniformly and rapidly penetrate fiber interiors, improving treatment effect and leveling.
- Dyeing process: 0.1%~0.3% (based on dye bath weight), promotes uniform dye penetration.
- Industrial hard surface cleaning/metal parts cleaning: 0.5%~1.0% (based on cleaning liquid weight), performs exceptionally well in high-pressure spray and CIP cleaning systems.
- Waste paper deinking: 0.1%~0.3% (based on absolute dry pulp weight), promotes separation of ink particles from fiber surfaces.
- Leather soaking/degreasing: 0.3%~0.8% (based on leather weight), accelerates soaking rehydration and removal of natural oils.
- Pesticide formulation synergist: 0.5%~2.0% (based on total formulation weight), acts as a wetting and penetration synergist.
Note: The above recommended dosages are general reference values. Actual optimal dosages vary due to specific process conditions (temperature, time, water quality, equipment type, etc.). It is recommended to conduct small-scale experiments to determine the optimal dosage. Source: Guoli Chemical Product Application Technical Guide.
Precautions
- The product is liquid and can be directly added to the working liquid. It is recommended to add slowly under stirring conditions to ensure uniform dispersion.
- Avoid direct high-concentration mixing with strong oxidizers to prevent adverse reactions.
- Storage temperature should be controlled at 5°C~35°C, avoid direct sunlight, and keep the container sealed.
- It is recommended to wear chemical safety goggles and protective gloves during operation, and wash hands thoroughly after operation.
- Although the product is not classified as a hazardous chemical, it should still be kept away from fire and heat sources. Eating or smoking at the operation site is prohibited.
- It is recommended to conduct small-scale tests before use to confirm compatibility with other chemicals in the system and optimal dosage.
- The final dosage should be determined comprehensively based on target wetting and penetration effects and cost control requirements.
