HPMC hydroxypropyl methylcellulose in building materials

CAS NO: 9004-65-3 EINECS NO.: 220-971-6  H.S. CODE: 391239
Molecular Formula: C12H20O10
 
HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural high molecular cellulose through series of chemical processing and achieved.With good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.

HPMC hydroxypropyl methylcellulose in building materials

1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks, which can enhance the strength of the cement.
2. Tile cement: improve the plasticity, water retention of the pressed tile mortar, improve the bonding strength of the tile, prevent powdering.

3. Gypsum coagulation slurry: Improves water retention and processability, and improves the adhesion to the substrate.

4. Seam cement: added to the joint cement for gypsum board to improve fluidity and water retention.

5. Coatings: As a plasticizer for latex coatings, it has an effect on improving the handling properties and fluidity of coatings and putty powder.

6. More.
