Generally speaking, the higher its viscosity, the better the water retention effect of the gypsum mortar. However, the higher the viscosity, the higher the molecular weight of the cellulose ether and the corresponding decrease in its solubility, which has a negative effect on the strength and construction properties of the mortar. The higher the viscosity, the more obvious the thickening effect on the mortar, but it is not a positive relationship.

Cellulose ether is commonly used in the fields of insulation mortar masterbatch, putty powder, asphalt roads and gypsum products, and have the ability to improve and enhance the characteristics of building materials and enhance the stability of production and construction suitability. The following is an introduction to the considerations caused by cellulose when using putty powder.

One of the biggest differences between dry mix mortar and traditional mortar is the modification of dry mix mortar with a small amount of chemical additives. Adding one additive to dry mortar is called primary modification, and adding two or more additives is secondary modification.

What properties of mortar can be improved by redispersible latex powder?

Redispersible Polymer powder is mainly used in all kinds of dry-mix mortar, such as wall putty powder, ceramic tile adhesive, ceramic tile jointing agent, dry powder interface agent, exterior insulation mortar, self-leveling mortar, mending mortar, decorative mortar, waterproof mortar, etc..

Redispersible Polymer Powder’s Functions:
Increase mortar’s impact resistance, durability, and abrasion resistance:

The polymer emulsion is prepared into a mixture that can be used for spray drying by adding different additives, and the addition of protective colloid and anti-blocking agent enables the polymer to form a free flowing powder that can redisperse in water after spray drying.

Choose hydroxypropyl methylcellulose based on characteristic of Substrate

redispersible polymer powder products are water-soluble re-dispersible powder, divided into ethylene/vinyl acetate copolymer, ethylene acetate/tertiary carbonate copolymer, acrylic acid copolymer, etc., the powder adhesive made after spray drying, with polyvinyl alcohol as the protective colloid.
