Wall putty is a material for filling the imperfections and smoothing the surface of walls. It is a cement-based fine powder that is indispensable before painting. Its excellent adhesion and tensile strength can extend the life of the wall paint. It can be used on both dry and wet walls, and also be applied on […]

Cellulose ether, such as hydroxypropyl methylcellulose (HPMC) and hydroxyethyl methylcellulose (HEMC), play a variety of key roles in cement-based putty formulations. These additives help improve the overall performance, workability, and quality of the putty. The following are the key roles of cellulose ethers in cement-based putties: Water retention: Cellulose ether have excellent water retention properties. […]

Influence on Rheology and Workability Cellulose ethers, such as HPMC (Hydroxypropyl Methylcellulose), significantly affect the rheological properties of tile adhesive. They influence factors like workability, slip resistance, and the consistency of the adhesive. Influence on Open Time In tile adhesive, both rubber powder and cellulose ether are present in the mortar. While the rubber powder […]

Cellulose ether includes many cellulose products. There are many cellulose products that can be used as water-retaining agents and thickeners. This article mainly introduces the cellulose ether hydroxypropyl methylcellulose (HPMC). When it comes to water-retaining, people may think of the effects of preventing water evaporation and loss, but the water-retaining effect of cellulose ether (HPMC) […]

Cellulose ether is a versatile material that has gained significant attention in the construction industry due to its numerous benefits. Derived from cellulose, a natural polymer found in plant cell walls, cellulose ether is widely used as an additive in various construction materials. Its high cellulose ether content makes it an ideal choice for enhancing […]

Cellulose ether is widely used in dry powder mortar such as tile adhesive, putty, self-leveling mortar, spraying gypsum, leveling gypsum, masonry mortar, plastering mortar, etc. Cellulose ether can slow down the rate of water loss of mortar. The dehydration of mortar includes two processes: one is that the water inside the mortar diffuses to the […]

A. The solubility and temperature of cellulose ether in water dependent on the degree of etherification. B. As the temperature increases, the water retention decreases. C. The higher the degree of etherification of cellulose ether, the better the high-temperature water retention of cellulose ether. Usually, the temperature of fresh-mixed mortar is below 35 degree Celsius […]

Water retention is the most important feature of cellulose ether in building materials. Keeping enough moisture in mortar can be satisfied with work-ability over a long time range. Water plays a lubricating and stirring role in the inorganic composition. The addition of a small amount of cellulose ether can keep enough water in the mortar for a […]

Hydroxy propyl methyl cellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved. HPMC is white powder with good water solubility. It has thickening, adhesion ,dispersing,emulsifying, film, suspended, adsorption, gel. In the course of construction,HPMC is […]
