Accepted Answer

If problems occur during use, it is recommended to first investigate based on the specific abnormal phenomena, and simultaneously contact the official technical support of Haian Guoli Chemical Co., Ltd. Detailed Explanation Super Penetrant JFC-E (Dioctyl Sodium Sulfosuccinate, CAS No.: 1639-66-3) generally performs stably in practical applications. However, if issues such as poor penetration, turbidity during compounding, abnormal foam, or stratification occur, preliminary troubleshooting can be conducted from the following aspects: 1. Usage Condition Check: Check whether the pH, temperature, and water hardness of the working solution are within the recommended range. JFC-E has good chemical stability in acidic, alkaline, and hard water systems, but extreme conditions (e.g., strong oxidizing agent environment, storage temperature beyond 5-35°C) may affect its performance. Confirm the correct addition sequence — this product is a nonionic surctant and generally does not cause precipitation when compounded with anionic, cationic, or amphoteric auxiliaries, but if added simultaneously with certain specific auxiliaries and stirred insufficiently, local high concentration may occur. 2. Product Condition Check: Normal appearance should be a colorless to slightly yellow transparent liquid. If the product appears turbid, stratified, or significantly darkened, it may have deteriorated due to improper storage (e.g., prolonged high temperature and sunlight exposure, unsealed container causing moisture ingress or contamination). Discontinue use of this batch. Application Recommendations Dosage Reference: The recommended dosage is generally 0.1% to 2.0% of the total working solution. The specific dosage should be determined by experiments based on process conditions and substrate type. Excessive use may lead to increased foam or heavier burden in subsequent cleaning processes. Addition Method: It is recommended to slowly add JFC-E to the working solution under stirring conditions to ensure thorough mixing. Avoid direct simultaneous addition with high concentrations of acids, alkalis, or oxidizers.

Question 5

What are the advantages of the super penetrating agent JFC-E compared to other similar products?

Accepted Answer

The core advantages of the super penetrating agent JFC-E lie in its 99% active content, ultra-st penetration speed of ≤5 seconds, excellent acid and alkali stability (can withstand 200g/L NaOH), and wide compatibility with various ionic auxiliaries. Its overall performance is leading among similar penetrating agent products. Detailed Description The super penetrating agent JFC-E (chemical name: Dioctyl sulfosuccinate sodium salt, CAS No.: 1639-66-3) is a high-purity anionic penetrating agent launched by Haian County Guoli Chemical Co., Ltd. Unlike the common JFC series non-ionic penetrating agents on the market (such as penetrating agent JFC-1 tty alcohol polyoxyethylene ether, high-temperature penetrating agent JFC-M isomeric tridecanol polyoxyethylene ether), JFC-E belongs to sulfosuccinate sodium salt surctants. Its unique molecular structure—double ester bond with sulfonic group—gives it extremely high intercial activity. The penetration speed measured by the standard canvas settling method is only ≤5 seconds, r superior to conventional non-ionic penetrating agents. Compared to the same sulfosuccinate series rapid penetrating agent T (st T-50, st T-70B, etc.), the biggest differentiating advantage of JFC-E is its ultra-high effective content (≥99%) and ultra-high purity (diester content ≥98%). Common st T products on the market are mostly 50%~75% alcohol-water solutions, while JFC-E is nearly pure. This means higher penetration efficiency at the same dosage, and lower transportation and storage costs. Additionally, its strict indicators such as moisture content ≤0.5%, free alcohol ≤1%, and acid value ≤1 mg KOH/g ensure batch stability and formulation reliability in high-end application scenarios (such as pesticide formulations, precision cleaning). Compared to phosphate ester penetrating agents (such as alkali-resistant penetrating agent AEP, low-foam penetrating agent SF), JFC-E maintains excellent alkali resistance (can withstand 200g/L NaOH), while having ster penetration speed, lower surce tension (28~32 mN/m), and good compounding compatibility with anionic, cationic, and amphoteric auxiliaries. It is less prone to precipitation or stratification, offering more flexible and free formulation design.
