CAS Number: 63148-62-9
Non-ionic PDMS silicone emulsion at 40% active solids. Balanced between the 30% ready-to-use grade and the 60% concentrate — higher active content than 30% grade for more economical shipping, easier to dilute evenly than 60% concentrate. pH 6.0–7.5, particle size D50 ≤1.5 μm. Widely used in textile finishing, paper release, and waterborne coating applications.
