The Quick Penetrating Agent Fast T-40 (Sodium dioctyl sulfosuccinate, CAS No.: 577-11-7) relies on its extremely low surface tension and rapid spreading ability to achieve deep wetting of fibers, powders, substrates, and biological surfaces in a very short time. This product exhibits excellent tolerance and stability in acid, alkali, and hard water systems, while also possessing low foaming characteristics, making it suitable for continuous industrial operations. Its wide compatibility allows it to be compatible with anionic, non-ionic, and most cationic systems, offering very flexible formulation adaptability.
In practical applications, Fast T-40 reduces the surface tension of the working fluid, significantly enhancing the speed and depth of chemical penetration into the target substrate, thereby shortening processing cycles, improving the utilization rate of active ingredients, and enhancing the uniformity and quality of the final product. The specific application processes are elaborated below by industry.
| Application Industry | Core Process Steps | Function and Effect |
|---|---|---|
| Textile Printing and Dyeing | Pretreatment (desizing, scouring, bleaching), dyeing, finishing | Quickly reduces the surface tension of dye liquors and treatment liquids, promoting the penetration of dyes and auxiliaries into fibers, significantly enhancing dye uptake and leveling, shortening wetting time, especially suitable for rapid processing of high-density fabrics. |
| Pesticide Formulations | Wettable Powder (WP), Water Dispersible Granules (WDG), Suspension Concentrate (SC), Aqueous Solution (AS) | Enhances the wetting and spreading ability of spray liquid on plant leaves and target organism surfaces, reducing droplet roll-off, thereby improving the effective utilization rate and control efficacy of pesticides. |
| Daily Chemical and Industrial Cleaning | General cleaning agents, heavy-duty cleaning agents, industrial parts cleaning | Imparts rapid penetration and emulsification performance to cleaning agents, effectively stripping various surface oils, carbon deposits, and stubborn stains, enhancing cleaning efficiency at room temperature and low temperatures. |
| Papermaking Industry | Sizing, coating processing | Improves the penetration depth and bonding uniformity of sizing and coating agents into the paper sheet, enhancing paper surface strength, smoothness, and printability, reducing linting and dusting. |
| Leather Making Industry | Soaking, degreasing, finishing | Accelerates the penetration of water and chemicals into leather fibers, shortening soaking and re-wetting time, improving degreasing efficiency and coating adhesion, enhancing leather softness and uniformity. |
When using Fast T-40, it is recommended to pre-dilute it before addition based on specific process requirements. In textile printing and dyeing pretreatment processes, the recommended dosage is generally 0.1%~0.5% of the working fluid (the exact dosage should be determined through trials based on fabric type and process conditions). When used as a wetting agent in pesticide formulations, the typical addition amount is 1%~5% of the total formulation weight. In cleaning formulations, it can be combined with non-ionic surfactants to achieve synergistic effects.
Due to its broad compatibility, the product can be used in conjunction with most anionic, non-ionic surfactants and auxiliaries. If it needs to be compounded with cationic systems, it is recommended to first conduct a small-scale compatibility test to confirm no precipitation or antagonism before bulk application.
