Cellulose Ethers and Their Uses
Depending on the production volume increasing day by day in the construction sector, the raw materials used also vary according to their performance. Cellulose ethers are among the most consumed products in the market for paint and construction chemicals.
Cellulose ethers raw material is high purity cellulose and is produced from cotton linter and pulp depending on viscosity. It is an environmentally friendly natural polymer, since its main source is wood. As a result of the special process called etherification, methyl cellulose (MC), hydroxyethylcellulose (HEC), methylhydroxypropylcellulose (MHPC) etc.
Special forms of cellulose ethers are produced and these special shapes have many different uses such as building materials, paint and coating industry, medicine, cosmetics, cleaning materials. Its biggest feature is that it can hold water in its body and it is used in the construction industry to provide and increase the binding, ease of application and water retention properties of products. Cellulose is insoluble in water while cellulose ethers, whose chemical synthesis is shown below, are water-soluble.
Cellulose ethers are ready for use in multiple forms and properties. Cellulose ethers can be examined in different groups, especially according to their production processes. According to this;
• Methyl cellulose (MC),
• Hydroxypropyl methyl cellulose (HPMC),
• Hydroxy ethyl methyl cellulose (HEMC),
• It can be listed as hydroxy ethyl cellulose (HEC).
Huacell products are used in many end product applications, giving the system the following features:
• Thickening (by increasing viscosity),
• Keeping the water within,
• Shear strength,
• Positive effect on adhesion,
• Binding effect,
• Helping to create movies,
• Easy application,
• Reducing surface tension.
It is used in building products, water-based paints, personal care, cosmetics, home care and cleaning products, emulsion polymerization, medicine etc. applications can be counted.
It is used in building products, water-based paints, personal care, cosmetics, home care and cleaning products, emulsion polymerization, medicine, etc. applications can be counted.
It has effects on water-based paints (interior, exterior, ceiling, etc.) by adjusting the rheology, thickening, providing easy application and preventing leakage, sagging or splashing. On the other hand, it also has a binding and open-time extender effect.
With its varieties in different viscosities, Huacell contributes to its rheological properties such as spreading and non-spattering, storage stability, open-time application time, opacity, film formation feature in the production of plaster and construction chemicals, and by keeping the water in its body for a long time, it provides good adhesion on the surface and prevents cracking.
Another usage area for the construction industry is construction chemicals products. Our Huacell 20 MP-Huacell 60 MP products are used in cement-based plasters, tile/ ceramic adhesives, decorative plasters, waterproofing products, sheathing products (ETICS), self-leveling screed products, gypsum-based products, in different viscosity ranges and modification degrees. It generally provides the following features:
HUACELL 20 MP
• Hydroxypropyl methyl cellulose is a non-ionic, water-soluble cellulose ether. It is available in tasteless odorless and fine powder form. Huacell 20 MP is a modified product. It is an excellent product to increase sagging resistance.

Gypsum is another binder for building products, and it is mostly preferred for interiors because it is not as resistant to water as cement.
Our Huacell GMC 30-Huacell GMC 40 products provide easy workability and optimum consistency to building products such as gypsum-based hand plaster, machine plaster, joint filler, adhesives, repair mortars, with the capacity to retain water for a long time, while preventing clumping at the same time.
Huacell, which is recommended for gypsum-based products, gives the system the following features in general.
HUACELL GMC 30
It is a nonionic, water-soluble cellulose ether. Available in tasteless odorless and fine powder.
