Hydroxypropyl methyl cellulose

Hydroxypropyl methyl cellulose (HPMC) is a natural polymer fiber through a series of chemical processing and preparation of non-ionic cellulose ether.
DB series HPMC is a modified cellulose ether product which is more soluble in water and developed specially for improving the performance of dry mixed mortar after surface treatment.

Product features: ☆ Increase water demand
High water retention, prolong the operating time of the material, improve the performance, avoid the appearance of crusting phenomenon, and help to improve the mechanical strength of the material.
Improve the operation performance, provide lubrication and uniform texture, make the material surface easier to wipe, so as to improve the construction efficiency, and improve the anti-cracking of putty.
Improve homogeneity, and improve anti-sag performance

Typical properties: Gel temperature: 70℃-91℃
Moisture content: ≤8.0%
Ash content: ≤3.0%
P H value: 7-8
The viscosity of solution is related to temperature. As the temperature of the solution increases, the viscosity begins to decrease until the gel is formed, and further increase in temperature will cause flocculation. This process is reversible.

The relationship between viscosity and water retention, the higher the viscosity, the better water retention. Generally speaking, the water holding capacity of cellulose is changed according to the temperature, and the increase of temperature will lead to the decrease of the water holding capacity.

Product application: Architecturally, it can provide excellent construction property and water retention for machine shotcrete and handmade mortar, dry wall caulking agent, ceramic tile cement glue and hooking agent, extruded mortar, underwater concrete, etc. In terms of adhesives, the consistency of adhesives and adhesives can be increased and a film can be formed in the adhesive dispersion. Coating can be used as thickening agent, protective colloid, pigment suspension agent, so as to improve the viscosity of waterborne coating stabilizer and solubility; It can increase water retention and lubrication in the process of ceramic processing.
