Self-Leveling Compound Additive (Casein & Redispersible Polymer)
CAS Number: 9000-71-9
Casein-based self-leveling compound additive functions as a flow agent and anti-sag modifier in cementitious self-leveling underlayments (SLUs). It imparts excellent flowability at low water-to-cement ratios while providing sufficient open time and preventing bleeding or segregation. Often combined with redispersible polymer powder to improve adhesion, flexibility, and wear resistance of the hardened compound.
