Alkali-Resistant Penetrant AEP
Jienuo
Alkali-Resistant Penetrant AEP is a high-performance surfactant designed for strong base environments. It effectively improves the permeability of solutions, enabling rapid penetration into fibers, textiles, or hard-to-reach surfaces even under high alkalinity.
Widely used in textile processing, dyeing, and industrial cleaning, it enhances the uniformity of treatments and boosts work efficiency. Compatible with alkalis, surfactants, and auxiliaries, it maintains stability in strong alkaline baths, ensuring consistent performance in harsh conditions.
Product Advantage
1. Exceptional Alkali Resistance: AEP can endure up to 200g/L of NaOH solution. This high alkali tolerance makes it ideal for applications in strongly alkaline environments, like textile pretreatment with high-concentration caustic soda baths.
2. Rapid Penetration: With a penetration time of ≤10 seconds when 7g of AEP is added to 1L of 120g/L NaOH solution, it quickly infiltrates materials. This feature ensures efficient processing in various industries, such as in the penetration of dyes in textile dyeing.
3. Broad Solubility: It is easily soluble in water and common organic solvents. This solubility property allows for seamless integration into different solution systems, facilitating its use in diverse industrial formulations.
4. Stability in Extreme Conditions: AEP shows excellent stability against high temperatures, oxidants, reductants, and hard water. It can maintain its performance even under harsh conditions, making it reliable for long-term and demanding applications.
5. Multi-functional Capabilities: In strong alkali conditions, AEP offers excellent functions like emulsification, degreasing, cleaning, dispersion, and antistatic properties. It is thus an essential ingredient in formulating high-quality pretreatment auxiliaries.

Product Uses
1. Pre-treatment in textile industry: During the scouring and boiling processes of cotton, linen, etc., adding AEP can enhance the penetration ability of the high-alkali solution to the fibers, facilitate the rapid detachment of impurities such as sizing and wax, improve the processing efficiency, and make the fabric feel more uniform.
2. In the dyeing industry: It is used in the dyeing process of reactive dyes and vat dyes, which can help the dyes quickly penetrate into the interior of the fibers in the strong alkali dye bath, reduce the problem of uneven dyeing, increase the dye uptake rate, and is especially suitable for dyeing thick fabrics.
3. Industrial cleaning: When adding AEP to the strong alkali cleaning solution for metals, ceramics, etc., it can enhance the solution's ability to penetrate and remove oil stains and oxide layers, shorten the cleaning time, and is suitable for high-pressure cleaning or soaking cleaning processes.
4. Papermaking and pulping: In the strong alkali environment of the paper pulp cooking process, AEP can accelerate the penetration of the reagent into the fibers, promote the decomposition of lignin, improve the pulping efficiency, and reduce the amount of chemicals used, thereby lowering production costs.
Product Operate Guide
When using the alkali-resistant penetrating agent AEP, add it to the working solution in a proportion of 0.5% to 3%, and stir evenly. Add it before processes such as textile processing and cleaning. It works best at room temperature to 80℃. Avoid mixing it directly with strong acids. After operation, store it sealed in a cool place. Ensure sufficient water to guarantee the penetration effect.
FAQ
1. What is the recommended concentration of the alkali-resistant penetrant AEP?
Generally, the recommended addition amount is 0.5% - 3%. The exact amount may vary depending on the specific working conditions. In strong alkaline environments or when dealing with difficult-to-penetrate materials, the concentration can be increased to 3%. In ordinary scenarios, 0.5% - 1% is sufficient. It is necessary to conduct a small-scale test to determine the optimal ratio first.
2. Can it be mixed with other additives?
It can be mixed with most alkaline additives and surfactants to enhance the synergistic effect. However, avoid mixing it directly with strong acids to prevent neutralization and loss of effectiveness. It is recommended to conduct a 50 mL small-dose compatibility test before mixing.
3. How to determine if the penetration effect meets the standard?
In the textile field, the speed of fabric wetting can be observed. If the fabric becomes fully wet quickly, it is considered effective. During cleaning, the time it takes for oil stains to be removed can be examined. If the time is shortened, it indicates that the standard is met. Alternatively, a comparative test can be conducted to determine if the concentration is appropriate.
