High temperature penetrant JFC-M (Isotridecanol polyoxyethylene ether), as a nonionic surfactant, has well-established usage methods in multiple industrial fields due to its excellent penetration, wetting, and high temperature resistance (cloud point 85~95°C), as well as alkali resistance (can withstand up to 200g/L NaOH).
Regarding Usage Method: The most core usage of this product is direct addition to various industrial liquid baths (such as dyeing baths, pretreatment liquids, and cleaning tanks). In the textile printing and dyeing field, it is mainly used as a penetrating leveling agent for high-temperature and high-pressure dyeing. It is typically injected into the circulation system along with dyes and auxiliaries during the preparation of the dye liquor; in pretreatment processes such as desizing and scouring, it can be used in the same bath as chemicals like caustic soda and hydrogen peroxide to promote the penetration of the chemical solution into the fiber interior. In metal cleaning, it serves as one of the core components of the cleaning solution and is directly added to the cleaning formulation. Regardless of the application, it is recommended to add it while stirring slowly to ensure uniform dispersion.
Regarding Recommended Dosage: The Guoli Chemical database does not specify the specific addition ratio of this product in the production process. This is because the optimal dosage highly depends on the type of material being treated, equipment type (such as overflow dyeing machines, jig dyeing machines), working fluid temperature, contact time, and final performance requirements. As an industry general reference, the initial trial range for nonionic penetrant products in general industrial working fluids is typically between 1~5 g/L, but this is not an official recommendation from Guoli Chemical and serves only as a starting point for exploration. It is strongly recommended that users combine on-site process conditions, start with a low dosage and conduct gradient small-scale tests to balance penetration effect and low foaming performance, thereby determining the precise dosage that best suits your needs.
