Generally speaking, the product descriptions provided by cellulose ether manufacturers will contain the following indicators: appearance, degree of substitution of viscosity groups, fineness, effective substance content (purity), moisture content, recommended areas and dosage, etc.

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

Water-retaining agent: Self-leveling materials are constructed on the ground base, and the construction thickness is relatively thin, and the water is easily absorbed by the ground base, resulting in insufficient hydration of the material, cracks on the surface, and reduced strength.

Dry mortar generally uses Portland cement as the cementing material, and the amount of cementing material generally accounts for 20% to 40% of the dry powder mortar; most of the fine aggregate is quartz sand, and the amount is large, and it generally needs to be dried and screened.

Vinyl acetate-co-ethylene copolymers (VAE), available from SLEOCHEM in powder form, are white, free-flowing, dry powders that are readily redispersed into water to re-form a stable emulsion. Sometimes called “solid latex,”

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.
