Product Details
Hydroxypropyl methylcellulose
HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation. White or whitish powder. HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.

Application
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, asbestos and other refractory coating: as a suspension agent, fluidity improver, but also improve the adhesion to the substrate.
4, gypsum coagulation slurry: improve water retention and processability, improve the adhesion to the substrate.
5. Joint cement: added to the joint cement for gypsum board to improve fluidity and water retention.
6. Latex putty: Improve the fluidity and water retention of putty based on resin latex.
7. Stucco: As a paste instead of natural material, it can improve water retention and improve the bonding force with the substrate.
8. Coating: As a plasticizer for latex paint, it has an effect on improving the handling properties and fluidity of paints and putty powder.
9. Spray coating: It has good effect on preventing the cement or latex coating from sinking and improving the fluidity and spray pattern.
10. Cement and gypsum secondary products: used as an extrusion molding binder for hydraulic materials such as cement-asbestos, which improves fluidity and provides uniform molded articles.
11. Fiber wall: It is effective as a binder for sand walls due to its anti-enzyme and antibacterial action.
12. Others: It can be used as a bubble retaining agent (PC version) which acts as a thin clay mortar and a mud hydraulic operator.
