Hydroxypropyl Methyl Cellulose For Mortar
●Enhance water retention, improve mortar, cement, gypsum building materials too fast drying and hydration is not enough to cause poor hardening, cracking and other phenomena
●Increase the plasticity of mortar to improve the workability of construction and improve work efficien
●Due to the increase of mortar plasticity, it can better bond the substrate and the binder
●Because of its thickening effect, it can prevent the slippage of mortar and binder during construction
Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether which is made by a series of chemical processing. They have water solubility, water retention, non-ionic type, PH stability, surface activity, temperature reversible gelatinization, thickening, bonding, film forming, lubricity and mold resistance and other properties. Therefore, it is widely used in thickening, cementification, suspension, dispersion stability, water retention, improve workability and other occasions.

Applied to putty characteristics
1. good water holding capacity makes cement hydration more complete.
2. improve the wet viscosity of wet mortar and improve the bonding strength of mortar.
3. improve the spraying or pumping performance of mortar and structural strength.
4. make the insulation system have good mechanical strength, crack resistance, durability and impact resistance.
