Chemical Name: Hydroxypropyl Methyl Cellulose
a non-ionic cellulose ether. It is an odorless, tasteless and non-toxic white powder,
which can be dissolved in hot or cold water to form a transparent viscous solution.
Full name - Hydroxypropylmethylcellulose
Methyl cellulose is not a toxic white powder with a yellowish tinge without taste and odor.
It absorbs water well, te is hydrophilic. As a result, the aqueous solution has an increased viscosity. It is added to the lime mortar, gypsum mixes, as well as to other building and varnish-and-paint materials. Used for the production of cement mixture and other types of solutions. Increases the bond strength of the dry mix for concrete preparation, increases the shear strength.
Due to the content of the necessary amount of hydrophobic methoxy groups, Methyl Cellulose is able to dissolve in certain organic substances, such as: Water and an organically mixed solvent.
Methyl cellulose has excellent oil-resistant properties.
Application
In building materials as a cementitious water-retaining solution, retarder for setting the inclusions of the building mix for transfusion.
In gypsum plaster, powder putty and other adhesives to improve spreadability and increase the working time with them.
As a tile adhesive, for marbles, decorative plastics, reinforcing inserts, it also reduces the use of cement.
HPMC: Due to the water retaining property, the paint can not dry out too quickly, eliminates cracks and increases strength after hardening.
It is used in the petrochemical industry, paints, building materials, solvents, agricultural chemistry, inks, textile printing and dyeing, ceramics, paper, cosmetics and other products as a thickener, stabilizer, emulsifier, filler, water-retaining and film-forming agent.
It works as a stabilizer for the suspension polymerization of a dispersant in PVC (PVC) It is the main additive in the preparation of suspension polymerization of PVC
