Hydroxypropyl Methylcellulose (HPMC) and Hydroxyethyl Methylcellulose (HEMC) are both crucial additives in the building materials industry, each offering unique properties that enhance the performance of various products. Here’s an overview of their roles in construction-grade applications: HPMC in Building Materials Key Properties: Water Retention: HPMC helps retain moisture, crucial for curing and achieving desired strength […]

Hydroxypropyl Methylcellulose (HPMC) is widely used in the building chemicals industry due to its versatile properties. Here are some of its key applications and benefits: Applications of HPMC in Building Chemicals Tile Adhesives: HPMC improves adhesion, workability, and open time, allowing for easier application and better bond strength. Mortars and Renders: It enhances the consistency […]

Vinyl acetate and ethylene are copolymerised in an emulsion process to produce a VAE composition with an ethylene content of 10% to 40% in the copolymer in the first instance. Ethylene is a soft, hydrophobic monomeric unit in the copolymer that acts as the internal “plasticising” part. In the copolymer, ethylene effectively lowers the glass […]

The redispersible polymer powder (RDP) has good flexibility, which can make the mortar respond to external changes in hot and cold environments, and effectively prevent the mortar from cracking due to temperature differences. Redispersible polymer powder in the mortar cavity and the surface of the film, in the cement mortar particles of the gap and […]

Water retention of cellulose ethers Water retention of mortar refers to the ability of mortar to retain  and lock moisture. The higher the viscosity of cellulose ether, the  better the water retention. Because the cellulose structure contains hydroxyl and ether bonds, the oxygen atom on the hydroxyl and   ether bond group is associated with the water […]

The water retention of cellulose is affected by many factors, including viscosity, addition amount, thermogelation temperature, particle size, degree of crosslinking, and active ingredients. Viscosity: The higher the viscosity of cellulose ether, the stronger its water retention capacity. This is because cellulose ether with high viscosity can better hinder the loss of water molecules. Addition amount: As the amount of […]

Water Retention: HPMC has excellent water retention properties, which help keep the skim coat hydrated longer. This is crucial for the proper curing of cementitious materials, resulting in a stronger and more durable finish. Improved Workability: The addition of HPMC improves the workability of the skim coat mixture. It makes the mix smoother and easier […]

Wall putty is a building material used to repair and smooth walls. It is usually mixed with raw materials such as gypsum, cement, lime, fillers and additives. Its main function is to fill in the unevenness of the wall surface, repair cracks and defects in the wall, and make the wall smoother and more beautiful. Wall […]

Performance Highlights Easy Mixing: It effortlessly blends with dry powder formulas and quickly dissolves without forming clumps upon adding water. Enhanced Water Retention and Thickening: Provides excellent water retention and thickening effects to mortar. Effective Solid Particle Suspension: Effectively suspends solid particles, resulting in a smoother and more uniform mixture. Construction Applications Improved Workability: Enhances […]
