Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose used in building materials, which can be dissolved in hot or cold water to form a transparent solution with a specific viscosity.
Normally HPMC is widely used in dry-mixed mortar industry, ceramic tile binder, external insulation system, self-leveling mortar, plastering, putty, paint and so on, it can improve construction performance, water retention performance, bond strength and sagging resistance.
Hydroxypropyl Methylcellulose (HPMC) are non-ionic cellulose ether & its derivatives that have hyrdroxyl groups on the cellulose chain substituted for a methoxy or hydroxypropyl group. HPMC is made from natural cotton linter under chemical reaction, which can be dissolved in both cold water and hot water to form a transparent solution. HPMC is used as a thickener, binder, and film former in construction, pharmaceutical, food, cosmetic, detergent, paints, adhesives, inks, PVC and various other applications.

The application in synthetic resin can make the obtained products have the characteristics of regular particles, looseness, appropriate specific gravity, excellent processing performance, etc., thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall building, plaster finishing, caulking, etc; Especially in decorative construction, it is used for pasting ceramic tiles, marble and plastic decoration, with high pasting strength, and can also reduce the amount of cement. Used as a thickener in the coating industry, it can make the layer bright and delicate, do not remove powder, and improve the leveling performance.
Function:
It can thicken the fresh mortar to have a certain wet viscosity and prevent segregation. (thickening)
Water retention is also the most important characteristic, which helps to maintain the amount of free water in the mortar, so that the cementitious material has more time to hydrate after the mortar construction. (water retention)
It has air entrainment, which can introduce uniform and fine bubbles to improve the workability of mortar.
Performance:
1. It is easy to mix with dry powder formula.
2. It has the characteristics of cold water dispersion.
3. The solid particles are effectively suspended to make the mixture more smooth and uniform.
Mix:
1. The dry mixed formula containing cellulose ether can be easily mixed with water.
2. Get the required consistency quickly.
3. Cellulose ether dissolves more quickly and has no lumps.
