Physical parameters:
The above two polymer powders pva 1788/2488 are particularly suitable for building mortar additives. They improve the flexibility and water retention of mortar and increase the viscosity of mortar. In addition, they can reduce the friction of mortar, thereby enhancing work efficiency and quality. (Prevent cracking and shedding of the plaster layer, increase the adhesion strength and smoothness.
The product is a fine particle polymer. Dispersed in water, it is widely used in premixed dry powder mortar. The powder can be quickly dispersed again in water to improve the characteristics of building materials.

Application range:

Textile industry: warp yarn sizing agent, fabric finishing agent, Nilun fiber raw material;

Construction: 107 glue, interior and exterior wall coatings, adhesives, dry mortar;

Paper industry: paper adhesives;


Recommended addition amount: 0.2-1.0% (polymer powder/cement)
