Dongyuan Shengda Cellulose ether is mainly used in cement render to improve water retention and workability. It helps prevent rapid water loss during application, promotes better cement hydration, and improves adhesion, spreadability, and surface smoothness while reducing cracking and segregation.
RDP is used to enhance the mechanical strength and flexibility of cement render. It forms a polymer film after curing, improving bonding strength, crack resistance, impact resistance, and water resistance, which helps improve the durability and weather performance of the render.
