The viscosity of HPMC is inversely proportional to temperature, that is, the viscosity increases as the temperature decreases. We usually say that the viscosity of a product refers to the result of testing its 2% aqueous solution at a temperature of 20 degrees Celsius.

After the PVA powder is mixed with other powders, the paste slurry is formed by adding water. After evaporation, the structure of inorganic and organic binder is formed, the brittle rigid skeleton of the water rigid material,

MC is methyl cellulose, which is made into cellulose ether by a series of reactions after the refined cotton is treated with alkali, using methyl chloride as the etherification agent. Generally, the degree of substitution is 1.6~2.0, and the solubility varies with the degree of substitution. Belongs to non-ionic cellulose ether.

The performance of polypropylene in dry mortar or concrete

1. Disperse evenly in the mortar to form a three-dimensional chaotic structure inside, which can lock the internal moisture of the mortar, and has a strong binding force;

Many friends who are engaged in the construction and decoration industry for the first time are very unfamiliar with these two kinds of latex powders, and even confuse them. The following mortar latex powder manufacturers will distinguish between putty powder and putty powder for you.

Since dry powder does not need to consider emulsion formulation and stability issues like polymer emulsions, a small amount of mixing can make the mortar achieve the required performance, and it is easier to package, store, transport and supply than emulsions, and is resistant to freezing and mildew.

The redispersible latex powder product is a water-soluble white or almost white flowable powder, a copolymer of ethylene and vinyl acetate, and polyvinyl alcohol as a protective colloid. A copolymer of esters with polyvinyl alcohol as a protective colloid.

Hydroxy Propyl Methyl Cellulose  ( HPMC ) 

CAS No.: 9004-65-3

1. water-soluble, non-ionic cellulose cellulose ether
2. odorless, tasteless, non-toxic, white powder
3. dissolved in cold water, forming a clear or slightly solution

Redispersible latex powder is the main additive of the new material cement dry powder mortar. It has been widely used in exterior wall insulation, coatings, floor mortars, polymer cement-based waterproof coatings and various building materials. As redispersible latex powder is a process in which emulsion is dried to produce latex powder,
