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.
