Core Advantages
1. Medium viscosity balances film toughness and slurry fluidity, avoiding blockage of coating heads under high solid-content coating.
2. Excellent adhesion to polyester, nylon and polyester-cotton blended fibers, less size shedding and stable breakage rate during weaving.
3. Soluble in warm water at ambient temperature without continuous high-temperature heat preservation, cutting heating energy consumption of production lines.
4. Low ash impurities; no yellowing under high-temperature drying or emulsion polymerization to stabilize finished product appearance.
5. Balanced protective colloid performance, compatible with vinyl acetate & acrylic emulsion polymerization without delamination during storage.
6. Wide compatibility with starch and water-based additives, high adaptability for construction & ceramic binder formulas.
