Hydroxypropyl methyl cellulose HPMC is mainly used as a high-efficiency water-retaining agent in building dry-mixed mortar. It can make the mortar have good plasticity and flexibility and improve the bond strength of the mortar. At the same time, HPMC can reduce the bleeding rate and stratification degree of mortar, improve the cohesion and flow resistance of […]

If the hot soluble type (Non-surface treated) HPMC is added directly to the water, agglomeration will occur before dissolution. However, dissolving in this way is very slow and difficult. Here we recommend three dissolution methods for end users based on different applications： 1 Hot water dissolution method: Since HPMC is not dissolved in hot water, […]

Improved processability One of the most notable advantages of using HPMC in tile adhesives is increased processability. HPMC acts as a thickener, providing the glue a smooth, creamy texture that is easy to apply. This uniformity enables for even spreading, minimizing the possibility of air pockets or uneven adhesion. As a result, tilers can work […]

1. Water Retention HPMC has excellent water-retaining properties. When mixed with skim coat materials, it helps to keep the mixture workable for extended periods. This is particularly advantageous during application, as it prevents the mixture from drying out too quickly, allowing for even and consistent application. The enhanced workability reduces the risk of cracking and […]

How to make wall putty paste? Making wall putty paste requires only three steps: preparing materials, mixing, and checking. 1. Prepare Raw Materials. Gather all the materials you need. White cement, RDP powder, fillers such as calcium carbonate. Measure the right amount of HPMC hydroxypropyl methylcellulose and add it to wall putty formulation. Prepare some water. 2. Mixing […]

Hydroxyethyl Methyl Cellulose (HEMC) is also named as Methyl Hydroxyethyl Cellulose (MHEC). It is a white, grayish-white, or yellowish-white granules. It is a non-ionic cellulose ether derived from the addition of ethylene oxide to methylcellulose. It is produced from a natural renewable polymer such as wood pulp or cotton. HEMC can be used as a […]

PROPERTIES OF HPMC for Drymix Mortar: * Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh. * Charring temperature: 280-300℃. * Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 ) * Real specific gravity: 1.26-1.31. * Browning temperature: 190-200℃. * Surface tension: (2% water solution) 42-56dyn.cm. * Properties: Dissolved in water and some organic […]

Daily chemical detergent grade hydroxypropyl methyl cellulose (HPMC) CAS9004-65-3 is a synthetic high molecular polymer prepared by chemical modification with natural cellulose as raw material. Detergent grade HPMC performance: Daily chemical grade HPMC is a white or slightly yellow powder, and it is odorless, tasteless and non-toxic. It can dissolve in cold water and organic […]

MHEC, or Methyl Hydroxyethyl Cellulose, is a chemical derivative of cellulose that is widely used in construction materials, including cement tile adhesives. It acts primarily as a water retention agent, thickener, and stabilizer in cement-based formulations. Here’s a bit more detail about its role and benefits in cement tile adhesives: Water Retention: MHEC improves the […]
