Hydroxypropyl methyl cellulose hpmc cellulose ether

Hydroxypropyl methyl cellulose(HPMC)

Hydroxypropyl methyl cellulose is a natural polymer cellulose used as a raw material, which is prepared by using a highly pure cotton cellulose as a raw material and by special etherification under alkaline conditions. They are an odorless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. Thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, surface activity, such as maintaining water and protective colloid properties.

The main purpose

As a water retaining agent and retarder for cement mortar, the mortar is pumpable. In the plaster, gypsum, putty powder or other building materials as a binder, improve the spreadability and extend the operation time. Used as a paste tile, marble, plastic decoration, paste enhancer, can also reduce the amount of cement. The water retention of hydroxypropyl methyl cellulose HPMC enables the slurry to not crack too quickly after application, and enhances the strength after hardening.

Recommended use

◇Tile adhesive
◇External wall moisturizing system
◇Grout
◇Self-leveling mortar

◇Plastering
◇Inner and outer wall putty
◇Paint, etc.

performance

Improve construction performance,
Improve water retention performance,
Improve bond strength,
Improve anti-slipping, etc.

Application area

1. Cement mortar: Improve the dispersibility 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 and water retention of the pressed tile mortar, improve the bonding force of the tile, and prevent the powder.

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.
