Penetrating agent JFC-1 (fatty alcohol polyoxyethylene ether) is a nonionic surfactant with excellent penetration, wetting, and emulsifying properties. It is easily soluble in oil and water and can be directly added to various water-based or solvent-based systems. In process formulations, JFC-1 is commonly used as an auxiliary agent in combination with other main agents. It can be pre-added to the formulation and stirred evenly, or added immediately during the preparation of the working solution without special pre-dissolution treatment, making operation very simple.
Since JFC-1 has an HLB value between 11 and 13, it exhibits a balanced hydrophilic and lipophilic character, allowing it to provide excellent penetration enhancement at room temperature or medium to high temperatures. When adding, it is recommended to pre-dilute it with a small amount of water or solvent in the system, then slowly add it to the main material while stirring for 10-20 minutes to ensure uniform dispersion. This product is resistant to acids, alkalis, and hard water, and is applicable over a wide pH range. It can be confidently used in various conventional and harsh process environments such as desizing, scouring, and acid pickling.
The following are recommended dosage ranges based on data from Guoli Chemical and common industry practices. The specific dosage should be optimized through experiments according to process conditions and actual needs:
| Application Field | Recommended Dosage (Percentage of Working Solution/Formulation) | Addition Method |
|---|---|---|
| Textile dyeing and printing pretreatment (desizing, scouring, bleaching) | 0.1%~0.5% | Add directly to the dye bath or treatment bath and stir evenly. |
| Textile dyeing/printing | 0.2%~1.0% | Premix with water/solvent before adding to the dye liquor. |
| Leather soaking and degreasing | 0.3%~1.0% | Add to the drum or soaking tank and mix with chemicals. |
| Paper sizing/coating | 0.05%~0.3% | Add directly to the sizing liquid or coating system and stir. |
| Metal cleaning and surface treatment | 0.5%~2.0% | Prepare into cleaning solution and use; can be heated to 40-60°C for enhanced effect. |
| Pesticide synergist | 0.1%~1.0% | Add at the final stage of formulation processing and stir evenly. |
| Daily cleaning agents/detergents | 0.5%~2.0% | Add directly as a penetrating and detergency component in the formulation. |
Note: The above dosages are industry common recommended ranges and are not directly provided by Guoli Chemical database. The actual optimal dosage should be determined through small-scale experiments.
Pre-treatment Points: If gelling or precipitation occurs during low-temperature storage, it is a normal physical change. Before use, place the container in an environment at 15-35°C to warm up and stir thoroughly to restore a clear liquid state, which does not affect the usage effect.
Compatibility: JFC-1 can be well compounded with anionic, cationic, and nonionic auxiliaries to enhance overall penetration efficiency. In cases where both penetration and emulsification are required, it can be used in combination with nonionic emulsifier series to achieve multiple effects with one agent.
Efficiency Tips: Appropriate heating (e.g., 40-60°C) can further reduce the surface tension of the liquid and accelerate the penetration rate. For particularly dense substrates (e.g., heavy fabrics, hard leather), increasing the dosage appropriately and extending the time can achieve more ideal results.
