Vinsol Resin Air-Entraining Agent
CAS: 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.

Viscosity Modifying Agent for Self-Compacting Concrete
CAS: 9004-32-4
Viscosity modifying agent (VMA) is a water-soluble polymer admixture that increases the viscosity and cohesion of self-compacting concrete (SCC) mixes, preventing segregation and bleeding while maintaining high flowability. Typically used in combination with PCE superplasticizers to achieve the required SCC rheological properties: high flowability (slump flow 550–800 mm) with adequate viscosity (T500 ≤ 5 s) and segregation resistance. Cellulose ether and welan gum grades are most common.
