PDMS Silicone Emulsion 30% Active
CAS Number: 63148-62-9
Non-ionic PDMS silicone emulsion at 30% active solids. Stabilized with non-ionic emulsifiers; pH 6.0–7.5; particle size D50 ≤1.0 μm. The finest particle size of the 30/40/60% series ensures uniform film formation on fiber and substrate surfaces. Ready to use directly or with minimal dilution in textile finishing baths, paper machine wet-end, and waterborne coating formulations.
