Redispersible Polymer powder is used in Internal and External Wall Putty. It is a kind of additive for building materials.  Redispersible Polymer powder is made by spray drying polymer emulsion. As the main adhesive of putty, redispersible emulsion powder has a significant effect on the bond strength of putty With the increase of the amount […]

Dispersible polymer powder is physically mixed with other inorganic binders(such as cement, slaked lime, gypsum, clay, etc) and various aggregates, fillers and other additives such as Hydroxypropyl Methylcellulose(HPMC), polysaccharide(starch ether) and cellulose, finally to produce mortar. When the dry mortar is added to the water and stirred, the rubber powder particles are dispersed into the […]

Hydroxypropyl methylcellulose (HPMC) is a commonly used additive in masonry mortar formulations. It serves various purposes, including improving workability, enhancing adhesion, and controlling water retention. Water retention is a critical property of masonry mortar as it affects the hydration process, workability, and long-term performance. In this context, we will explore the water retention capabilities of […]

Hydroxypropyl methylcellulose (HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using pure cotton as a raw material. Mainly used in the construction industry: water-resistant putty powder, putty paste, steel putty, paint glue and masonry mortar, dry powder insulation mortar and other dry powder building materials. Hydroxypropyl methylcellulose (HPMC) is a kind […]

HPMC for Tile Adhesive Hydroxypropyl methyl cellulose(HPMC)-short name Hypromellose. HPMC is off-white powder in appearance. HPMC could dissolved in water and forms colloids. It is no-toxic. Dry mix mortar is one of HPMC main applications, hereby, we will let you know the detailed functions of HPMC in tile adhesive application. Functions of HPMC for Tile Adhesive […]

HPMC is odorless, tasteless,non-toxic cellulose ether produced from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film,suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties etc. HPMC Features HPMC use for Water Retention: […]

Adding an appropriate amount of HPMC to tile adhesives can significantly improve their overall performance. Studies show that an HPMC content of about 0.2%-0.5% is generally sufficient to achieve desired results. The specific benefits include: – Extended Open Time Provides greater flexibility during application, reducing rework. – Enhanced Anti-Slip Properties Prevents tiles from slipping, especially […]

Thickening Effect HPMC serves as a thickening agent in tile adhesives, significantly increasing the consistency of the slurry and preventing sagging during application. This is particularly crucial for vertical surfaces, where the adhesive must stay in place to ensure proper tile adhesion. Water Retention HPMC’s excellent water retention properties slow down the evaporation of water, […]

In the building materials industry, cellulose ethers have an extremely wide range of uses. The amount is large and they can serve as retarders, water-retaining agents, thickeners and binders. Cellulose ethers play important roles in ordinary dry mortar, efficient exterior wall insulation mortar, self-leveling mortar, dry plaster adhesives, dry mortar for tile adhesive, high-performance construction […]
