Products for Self-leveling
RDP, HPMC, and HEMC are fundamental additives in self-leveling compounds, working in synergy to balance high fluidity, stability, and early strength.
RDP enhances flexibility, adhesion, and crack resistance. It forms a polymer network that accommodates substrate movement and shrinkage stresses, prevents delamination, and improves surface durability.
HPMC & HEMC provide critical viscosity control and water retention. They prevent segregation and bleeding while ensuring sufficient water remains available for cement hydration and RDP film formation.
Together, this combination ensures excellent flowability, a homogeneous mixture, and a durable, crack-resistant floor surface, making it essential for high-performance self-leveling applications.
