High-purity acrylate-modified polysiloxane——High-performance fluorine-free acrylic waterproofing agent preferred Changfu chemical

With the continuous upgrade of the EU REACH regulations and the comprehensive ban on PFAS, environmentally friendly fluorine-free waterproofing has become a rigid threshold and a necessary route for textile exports. The traditional pure acrylic waterproof system has long been constrained by issues such as a hard feel, white marks from scratches, water permeability and peeling, fabric surface hardening, and emulsion stratification, which have consistently limited the quality and stability of the fabric.

To overcome industry bottlenecks, Changfu Chemical has launched high-purity acrylate-modified polysiloxane. With its terminal active double-bond structure, it perfectly copolymerizes modified acrylic emulsions, creating a new generation of environmentally friendly, high-performance, fluorine-free waterproof solutions.

Product Features:

✅ High-purity small molecules・More uniform film formation

     Small molecular structure features strong permeability, enabling it to penetrate deep into the warp and weft of fibers, form uniform films on both sides without surface difference and color deviation. It boasts excellent compatibility with acrylic emulsion, causing no delamination, emulsion breaking or oil floating. It keeps barrels clean with stable storage performance and is compatible with all production processes.

✅ Covalent Co-polymerization with Double Bonds・Significant Improvement in Wash Resistance

Contains active double bonds, which graft onto the acrylic resin free radicals during the baking stage, ensuring non-physical blending, no migration, and no silicone running; thoroughly addresses the shortcomings of regular silicone oil, which easily falls off and loses water resistance. It maintains a high water-repellent rating even after more than 30 washes, with no decline in performance over time.

✅ Siloxy Softening Modification - Say Goodbye to Hard Creases

Incorporating smooth siloxy segments to improve the brittleness and hardening of acrylic film formation; the fabric becomes silky and soft, eliminating claw marks, crease whitening, and dead prints, while retaining breathability. Compatible with all categories of cotton, polyester, nylon, knitted, and woven.

✅ Low Surface Energy・Lotus Leaf Water Repellency

The silicon chain features ultra-low surface energy, which greatly increases the water contact angle and simultaneously improves water repellency grade, rain penetration resistance and hydrostatic pressure resistance. Water droplets roll off more rapidly, delivering a lotus leaf effect comparable to that of fluorine-containing products. Adopting a completely fluorine-free formula, it is eco-friendly and fully compliant with relevant regulations.

✅ High Purity Low Yellowing・Color Stability and Reliability

High purity, low impurities, resistant to yellowing and minimal color change during high-temperature baking; free from PFAS, PFOA, PFOS, APEO, meeting the latest EU environmental standards.

It can be compounded with our company's medium to high molecular weight mono-end acrylate-modified polysiloxane to achieve a four-in-one effect of penetration + softness + high water repellency + strong wash resistance, aiding in the upgrade of high-end fluorine-free acrylic waterproof agents.
