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,

The water retention of dry mortar refers to the ability of the mortar to retain and lock moisture. The higher the viscosity of hydroxypropyl methyl cellulose ether, the better the water retention. Since the cellulose structure contains hydroxyl and ether bonds, the oxygen atoms on the hydroxyl and ether bond groups associate with water molecules to form hydrogen bonds, so that free water becomes bound water,

Hydroxypropyl methyl cellulose HPMC is used as a dispersant, thickener and binder in construction treatment, and is mainly used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage, and have water retention. Reduce the moisture loss and strength of the concrete surface, prevent cracks and weathering of water-soluble salts;

The special latex powder for tile adhesive is a new type of tile adhesive made by using cement as a gelling agent, adding high molecular polymers and inorganic powders as water-retaining agents and adhesives. It can also be applied to thin tiles. Layer bonding.

Redispersible latex powder is a powder binder made from a special polymer emulsion spray-dried. This powder can be quickly redispersed to form an emulsion after contact with water, and has the same properties as the initial emulsion. Therefore, the emulsion used for the production of redispersible latex powder should also have the following special properties compared with ordinary emulsions directly used for adhesives:
