At present, many masonry and plastering mortars have poor water retention performance, and the water slurry will separate after a few minutes of standing. So it is very important to add an appropriate amount of cellulose ether to the cement mortar. 1. Water retention of cellulose ether Water re...Read more »

Self-leveling mortar can rely on its own weight to form a flat, smooth and strong foundation on the substrate for laying or bonding other materials, and at the same time it can carry out large-scale and efficient construction. Therefore, high fluidity is a very significant aspect of self-leveling...Read more »

Redispersible polymer powder is often seen in construction as an external wall insulation material. It is mainly composed of polystyrene particles and polymer powder, so it is named for its particularity. This kind of construction polymer powder is mainly formulated for the particularity of polys...Read more »

After adding hydroxypropyl methylcellulose to cement-based materials, it can thicken. The amount of hydroxypropyl methylcellulose determines the water demand of cement-based materials, so it will affect the output of mortar. Several factors affect the viscosity of hydroxypropyl methylcellulose:...Read more »

Due to factors such as air temperature, humidity, wind pressure, and wind speed, the volatilization rate of moisture in gypsum-based products will be affected. So whether it is in gypsum-based leveling mortar, caulk, putty, or gypsum-based self-leveling, hydroxypropyl methylcellulose ether (HPMC)...Read more »
