Polyvinyl alcohol powder (2488) is a white, small particle, stable and non-toxic water-soluble polymer, mainly used as an additive in construction mortar and in the field of dry powder mortar.

1 Building mortar additives

Polyvinyl alcohol powder (2488) is particularly suitable as an additive for building mortar. It can be used in combination with cellulose ether based water retaining agents to improve the flexibility and water retention of cement mortar and gypsum building materials, and increase the viscosity of mortar. In addition, it can reduce the friction of mortar, thereby enhancing work efficiency and quality, preventing cracking and detachment of the plaster layer, and increasing its adhesion strength and smoothness. The adhesive strength of polyvinyl alcohol powder is 2.5-3 times higher than that of redispersible latex powder, with a long service life and a significant reduction in production costs.

2 Putty building materials

The use of polyvinyl alcohol powder (2488) in gray calcium based putty is very small, which can significantly improve the cohesive strength, adhesion, and water resistance of the putty coating. At the same time, it can also significantly improve the phenomenon of delamination and scarring during polishing, and improve the surface smoothness of the putty after polishing. In addition, polyvinyl alcohol powder can also improve the solidification rate of cement in cement-based putty, with good film-forming properties, excellent durability, and a thin batch that is not easy to remove powder.

3 Rapid sol water powder class

Polyvinyl alcohol powder (2488) is one of the main binders in the quick sol water powder category. It can be combined with an appropriate amount of hydroxypropyl methyl cellulose, supplemented by an appropriate amount of thickening and complexing agent, to obtain a convenient, environmentally friendly, and high bonding strength double fly powder. At the same time, the product can also be mixed with cement gypsum for wet wall leveling.

4 Dry powder mortar class

Polyvinyl alcohol powder (2488) has good film-forming properties. When used in combination with cellulose ether based water retaining agents, it can improve the flexibility and water retention of various cement mortar and gypsum building materials, enhance the bonding strength of mortar, and effectively prevent peeling, cracking, and hollowing. In addition, this product can also be used in multiple fields such as thin layer adhesives, flexible adhesives, mineral plasters, cement additives, PVC latex, re wetting adhesives, etc.

5 Other

Polyvinyl alcohol powder (2488) also has various other uses, such as office paste, cosmetics, screen photosensitive film, coating agent for copperplate paper, zinc plate printing photosensitive film, sizing agent for long fiber yarn, etc.
