Vinsol Resin Air-Entraining Agent
CAS Number: 8050-09-7
Vinsol resin-based air-entraining agent (AEA) is derived from wood rosin and introduces a stable, uniform network of microscopic air bubbles into concrete. This entrained air system dramatically improves freeze-thaw resistance and scaling resistance of hardened concrete, and also enhances fresh concrete workability. It meets ASTM C260 and EN 934-2 standards and is suitable for all Portland cement types.
