Penetrant JFC-1 is a high-purity (≥99%) nonionic surfactant with extremely low surface tension (28~32 mN/m) and rapid penetrating power (≤5 seconds). It has stable physical and chemical properties and is readily soluble in both water and oil.

Detailed Description

The chemical name of Penetrant JFC-1 is fatty alcohol polyoxyethylene ether (CAS No.: 9036-19-5), with a molecular formula of C₁₂₋₁₄H₂₅₋₂₉O(C₂H₄O)ₙH (n≈5) and an average molecular weight of approximately 400~600. The product appears as a colorless to light yellow transparent liquid and belongs to the nonionic surfactant category. It is liquid at room temperature (melting point below -5°C), with a flash point above 100°C. It is classified as a non-hazardous material, and storage and transportation under normal conditions are safe and controllable.

Due to the polyoxyethylene chain segment in its molecular structure, this product exhibits excellent surface activity. Its HLB value is between 11 and 13, providing a balanced hydrophilic-lipophilic property that endows the product with outstanding wetting, penetrating, emulsifying, and dispersing capabilities. The pH value of a 1% aqueous solution is weakly acidic to neutral (5.0~7.0), and it maintains stable physical and chemical performance in acidic, alkaline, and hard water media.

Application Recommendations

Based on the above physical and chemical properties, the recommended applications of Penetrant JFC-1 in different scenarios are as follows:

  • Textile Dyeing and Finishing: Recommended dosage is 0.1%~0.5% of the working solution. Utilizing its HLB value of 11~13 and low surface tension (28~32 mN/m), it achieves rapid and uniform penetration, avoiding uneven dyeing. The cloud point of 45~55°C makes it optimal for medium and low temperature processes.
  • Metal Surface Treatment: In cleaning and degreasing processes, recommended addition is 0.5%~2%. Its alkali resistance and excellent penetrating power (≤5 seconds) accelerate the penetration and stripping of oil stains by the treatment solution, and the low foam characteristic facilitates subsequent rinsing operations.
  • Pesticide Formulations: Used as a tank-mix adjuvant or formulation component with an addition amount of 0.01%~0.1%. Its extremely low critical micelle concentration (0.8~1.5 g/L) can significantly reduce the surface tension of the spray solution, enhancing the wetting, spreading, and penetrating ability on target surfaces.

Precautions

  • Storage Conditions: Ideal storage temperature is 5~40°C. Avoid prolonged exposure to extremely low temperatures (below -5°C may cause gelation or precipitation). Keep containers sealed to prevent moisture absorption.
  • Safety Protection:
