The role of dispersible polymer powder in putty powder
1. Putty is used as a material for pretreatment of the surface to be coated in architectural coatings Putty is a thin layer of leveling mortar. Putty is scraped on the surface of rough substrates (such as concrete, leveling mortar, gypsum board, etc.) Make the exterior wall paint layer smooth and...Read more -

Dispersible polymer powder properties, advantages and application fields
Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic copolymers, etc. agent, with polyvinyl alcohol as protective colloid. This powder can be quickly red...Read more -
The benefits of dispersible polymer powder in mortar
In mortar, redispersible latex powder can improve the engineering construction characteristics of rubber powder, improve the fluidity of rubber powder, improve thixotropy and sag resistance, improve the cohesive force of rubber powder, improve water-solubility, and increase the time when it is op...Read more -
Properties and uses of redispersible polymer powders
Redispersible latex powder is a powder dispersion processed by spray drying of modified polymer emulsion. It has good redispersibility and can be re-emulsified into a stable polymer emulsion after adding water. The performance is exactly the same as the initial emulsion. As a result, it is possib...Read more -
Basic knowledge of dispersible polymer powder
1. basic concept Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based. Redispersible latex powder is a polymer emulsion that is spray-dried and aggregated from the initial 2um to form spherical particles of 80~120um. Because the ...Read more -

It is a powder dispersio...Read more -
The necessity of adding hydroxypropyl methylcellulose (HPMC) to mortar and gypsum-based products!
In cement mortar and gypsum-based slurry, hydroxypropyl methylcellulose mainly plays the role of water retention and thickening, which can effectively improve the cohesion and sag resistance of the slurry. Factors such as air temperature, temperature and wind pressure will affect the evaporation ...Read more -
The main uses and differences of hydroxypropyl methylcellulose HPMC and hydroxyethyl cellulose HEC
There are industrial monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, and hydroxyethyl cellulose, which are the most used. Among the three types of cellulose, the most difficult to distinguish is hydroxypropyl methylcellulose and hydroxyethyl cellulose. Let us distin...Read more -
Hydroxypropyl methylcellulose use classification?
Hydroxypropyl methylcellulose is divided into two types: ordinary hot-melt type and cold-water instant type. Hydroxypropyl methylcellulose uses 1. Gypsum series In gypsum series products, cellulose ethers are mainly used to retain water and increase smoothness. Together they provide some relief. ...Read more -
Hydroxypropyl methylcellulose HPMC
Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline conditions. Widely used in construction, chemical, pharmaceutical and other industries. c...Read more -
What factors affect the water retention of hydroxypropyl methylcellulose
The higher the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods are Haa...Read more
