With the rapid development of modern building construction, dry-mix mortar systems such as tile adhesive, wall putty, and plaster mortar require stable workability, strong adhesion, and reliable water retention. Hydroxypropyl Methyl Cellulose HPMC has become a key functional additive to meet these performance demands.

Hydroxypropyl Methyl Cellulose (HPMC) is a widely used cellulose ether in the construction industry. It plays a vital role in improving workability, water retention, and consistency of cement-based and gypsum-based materials. As a key HPMC for construction, it is commonly applied in tile adhesive, dry mix mortar, wall putty, plastering mortar, and self-leveling systems.

Hydroxypropyl Methyl Cellulose (HPMC) is a key cellulose ether widely used in modern construction materials, especially in dry-mix mortar systems. Acting primarily as a water retention agent and rheology modifier, HPMC plays a critical role in improving application performance, consistency, and final quality of cement-based products.

Water: Hydroxypropyl methylcellulose is soluble in water, and the aqueous solution is surface active, highly transparent and stable.

In the field of building materials, Hydroxypropyl Methyl Cellulose (HPMC ) is being regarded as a revolutionary product. Its multifunctional properties not only improve construction efficiency, but also greatly improve the performance of building materials. This renewable polymer brings a host of advantages to the construction industry, making it an emerging favorite.

HPMC, or Hydroxypropyl Methylcellulose, is a versatile chemical compound that is widely used in the construction industry. It is a type of cellulose ether that is derived from natural cellulose and is a water-soluble polymer. HPMC is used in various applications in the construction industry, including:

Hydroxypropyl methyl cellulose is a synthetic polymer made from natural cellulose through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its most basic material is cellulose, a natural polymer compound. Due to the special structure of natural cellulose, cellulose itself has no ability to react with etherifying agents. However, after treatment with the swelling agent, the strong hydrogen bonds between and within the molecular chains are destroyed, and the active release of the hydroxyl group becomes alkali cellulose with the ability to react. After the reaction of the etherifying agent, the -OH group is converted into the -OR group. Cellulose ether is obtained.

1. Cement mortar: improve the dispersion of cement sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks and enhance the strength of cement.

HPMC is a non-ionic cellulose ether polymer, which has different chemical properties according to the degree of substitution of the substituent groups and the degree of modification. It is a non-ionic, odorless, odorless white fiber Pure ether powder.

Gypsum mortar is a building material with gypsum as the main component. Gypsum accounts for 70% to 80% of the total weight of the mortar. Other components include lime, silicate, etc. The following is a summary of the effects of several mortar additives on gypsum mortar.

(1) Whiteness: Although whiteness cannot determine whether HPMC is easy to use, and if whitening agent is added in the production process, its quality will be affected. However, most good products have good whiteness.

Hydroxypropyl methyl cellulose plays three roles in the putty powder: thickening, water retention and construction.
