oyforce hydroxypropyl methyl cellulose ether is a functional cellulose ether, suitable for self-leveling mortar, with the following characteristics: Low viscosity to ensure the flow properties of the mortar. Reduce the water sensitivity of the mortar, reduce settlement and bleeding, and improve the strength and wear resistance of the surface after the mortar is hardened. High gel temperature, giving the mortar excellent water retention properties. It has a wide range of adaptability with different systems of cement-based and gypsum-based fluid mortar.
