Epoxy silicone oil emulsions are stable dispersion systems formed by the emulsification of epoxy-functionalized polysiloxanes. The Si-O-Si structure of the molecular backbone and the synergistic effect of the side-attached epoxy functional groups endow it with multiple excellent properties. Its core advantage lies in its strong reactivity; the epoxy groups can undergo ring-opening crosslinking with the active hydrogen in substrates such as fibers and leather to form a firmly bonded, flexible film layer that combines softness and durability. The emulsion exhibits outstanding stability, with a number-average particle size controlled between 50-200 nm. It possesses excellent centrifugal, freeze-thaw, and thermal storage stability, and can be dispersed with water in any proportion, making it convenient and environmentally friendly to use.
In basic applications, textile printing and dyeing is the core scenario, accounting for 35-40%. Used in the finishing of cotton, linen, synthetic fibers, and fabrics, it can significantly improve the smoothness, elasticity, and wrinkle resistance of the hand, enhance tear strength, and improve resistance to washing and dry cleaning, making it suitable for the finishing needs of light-colored fabrics. In the thread manufacturing industry, it optimizes the performance of high-speed sewing threads, reduces breakage rates, and improves sewing efficiency. Furthermore, as a leather release agent, it forms a protective film on the leather surface, providing both anti-sticking and conditioning benefits, while also improving the softness and combability of wig products, offering a low-cost, high-efficiency solution for the light industry.
