As a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer, Hydroxypropyl Methyl Cellulose（HPMC） is s a hydrophilic polymer material by increasing the viscosity of mixing water to increase the consistency of its mixture and can be dissolved in water to form a solution or dispersion.

1. Hydroxypropyl methyl cellulose can enhance the adhesion to the surface of the wall, enhance water-holding capacity, and thus improve the strength of mortar.

The redispersible powder is a special water-based emulsion made by spray drying and a polymer binder prepared mainly based on the vinyl acetate-ethylene copolymer. After partial evaporation of water, polymer particles form a layer of polymer film by agglomeration and play the role of adhesive

As a kind of basic additive in mortar formulation, it can provide good water retention, increased adhesion strength and improved workability. Wildly used in many kinds of dry mix mortar products.

In the use of hydroxypropyl methyl cellulose HPMC, we usually find that it is basically divided into two types: immediate and slow dissolution. Let us understand the difference between quick dissolution and slow dissolution of hydroxypropyl methyl cellulose.

1. The aqueous solution of pure hydroxypropyl methyl cellulose is clarified with high transmittance and the water retention rate of > 95%; Adulterated HPMC water solution is more than 80 %.

Strengthen the adhesion to the surface of the masonry, and can enhance the water retention, so that the strength of the mortar can be improved. Improve lubricity and plasticity to improve construction performance, easier to apply, save time, and improve cost-effectiveness.

Low viscosity hydroxypropyl methyl cellulose (HPMC) has good water solubility, high transparency, good gel performance, strong fluidity and surface activity. It is widely used in medicine and food, petrochemical, construction, textile and electronics industries.
