METHYL CELLULOSE

Methylcellulose for building systems

Cellulose ethers from SE Tylose GmbH & Co. KG

 SE Tylose GmbH & Co. KG is a German subsidiary of the ShinEtsu Group, headquartered in Japan.
SE Tylose GmbH & Co. KG, based in Wiesbaden, Germany, develops, manufactures and markets various water-soluble cellulose ethers under the Tylose® brand name.
They are most often used in the production of paints and building materials, as well as in polymerization. In addition, Tylose is used for the refinement of various products in a wide variety of areas, such as in the pharmaceutical industry, ceramics, oil production, as well as in cosmetics.

 The assortment includes:
• methyl cellulose (MHEC, MHPC)
• hydroxyethyl cellulose (HEC)
• other additives

 Methylcellulose (MHEC, MHPC)
Methyl cellulose (MC) can be considered as a general term for mixed esterified cellulose ethers. Methoxylation has similar properties with these cellulose ethers. Additionally, there is an exchange with ethylene or propylene oxide. This produces the following end products:
• Methyl Hydroxyethyl Cellulose (MHEC) under the trademark Tylose® MH
• Methyl Hydroxypropyl Cellulose (MHPC) under the trademark Tylose® MO
Tylose MH and Tylose MO are water-soluble nonionic cellulose ethers that impart, for example, the following properties:
• significant water retention capacity
• astringency
• thickening
• protective colloidal effect
• film formation
Tylose MC products contribute to the exceptional performance of a variety of products in a wide range of applications. Examples include building materials, paints, ceramics, and detergents.

 Tylose® properties
Tylose is a free-flowing powder or granules, the color of which ranges from white to slightly yellowish. It is odorless, tasteless and contains residual moisture due to production conditions, as well as a small amount of residual salts. Tylose can also contain other additives, which, for example, control the solubility and dispersibility, or target the development of the viscosity. Depending on the area of ​​application, Tylose is offered in unmodified and modified form.
We will dwell on the most important properties of Tylose below:
• solubility
• thickening effect
• surface activity

 Water holding capacity

Water retention in building materials is the most important property of Tylose® MC-types. Keeping a sufficient amount of water in the mortar for quite a long time is necessary for easy handling. Water acts as a lubricant between inorganic elements. In this way, the thin-layer mortar can be whipped and the plaster spread with a trowel. Pre-wetting the absorbent wall or ceramic tiles can be dispensed with. Thus, the application of Tilosa MC enables fast, efficient construction. Cement and gypsum binders require water for hardening (hydration), with the help of a certain amount of Tylose MC-types, the water is kept in solution for as long as necessary for a uniform hardening process.

Consistency and resistance to slipping
For everyone who processes mortar, consistency and creep resistance are very important properties. The mortar must be easy to process, but at the same time exhibit high resistance to slipping. Plaster, even in thick layers, should not settle; ceramic tile adhesives should hold heavy tiles on vertical surfaces.

 Adhesion
The adhesion of mortars to the base is achieved primarily through the binding properties of cement, gypsum, calcium hydroxide and dispersed powder. Tylose® MC-types can function as an astringent. For example, in wallpaper adhesives, Tylose MC is used as the sole binding agent. The wet and dry adhesion of mortars is improved by using Tylose® MC. The property of MC to retain water in solution enables the necessary hydration of cement and gypsum binders.

 Other additives

For applications in the field of building materials, SE Tylose GmbH & Co. KG offers, in addition to cellulose ethers, the following powder products:
- starch ether under the trademark Tylovis® SE 7
- surfactants under the trademarks Tylovis® LO 19, Tylovis® EP 28
