The Role of Hydroxypropyl Methylcellulose in Diatomaceous Earth Coatings.-HPMC

HPMC is one of our best-selling products, offering a low price and high quality. It can be used as a thickening and water-retaining agent in construction. Shijiazhuang Cellulose Co., Ltd. is a cellulose manufacturer from China and can provide you with a sufficient supply.

Diatomaceous earth paint is an interior decorative wall material primarily made from diatomaceous earth.  It possesses functions such as formaldehyde removal, air purification, humidity regulation, negative ion release, fire resistance, self-cleaning, and antibacterial and deodorizing properties. Due to its health and environmental benefits, diatomaceous earth paint offers both excellent decorative qualities and functional advantages, making it a new generation of interior decorative material that can replace wallpaper and latex paint.

The hydroxypropyl methylcellulose (HPMC) specifically used in diatomaceous earth paint is a non-ionic cellulose ether made from natural polymer cellulose through a series of chemical processes. It is an odorless, tasteless, and non-toxic white powder that swells in cold water to form a clear or slightly cloudy colloidal solution. It possesses properties such as thickening, binding, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisture retention, and colloid protection.

The role of hydroxypropyl methylcellulose in diatomaceous earth plaster:

It enhances water retention, preventing problems such as poor hardening and cracking caused by rapid drying and insufficient hydration of the diatomaceous earth plaster.

It increases the plasticity of the diatomaceous earth plaster, improves workability, and increases work efficiency.

It allows for better adhesion to the substrate and the materials being bonded.

Due to its thickening effect, it prevents the diatomaceous earth plaster and the bonded materials from shifting during construction.

Diatomaceous earth plaster itself is non-polluting, purely natural, and has multiple functions that traditional coatings such as latex paint and wallpaper cannot match. When decorating with diatomaceous earth plaster, there is no need to move out of the house because there is no odor during the application process, it is purely natural, and easy to repair. Therefore, the selection of hydroxypropyl methylcellulose for diatomaceous earth plaster requires high standards.
