ZEMSIL SL-AC

English

ZEMSIL SL-AC is an acidic colloidal silica dispersion containing 20% SiO₂ stabilized at pH 2–4, with an ultra-low sodium content below 0.05% Na₂O. The fine 5–15 nm particles and acid-stable formulation make it uniquely suited for integration into acid-catalyzed coating systems and precision casting formulations where sodium contamination or pH incompatibility would disqualify alkaline grades. It provides excellent film-forming properties and reinforcement at low addition levels.
