CMC Carboxymethylcellulose Additives , Hydroxyethyl Cellulose HEC, Methyl Hydroxyethylcellulose MHEC, methyl Hydroxypropyl Cellulose MHPC, Hydroxy HPC methylcellulose propyl And ethyl hydroxy ethyl cellulose EHEC Mostly known as tylos. Considering the importance of Environmental issues today are witnessing the growing trend of water-based paint consumption in Iran and the world Are. One of the most important components in the production of this type of paint is concentrators. Cellulose concentrators have grades from 4000 to 200000, which are in the adhesive industry Painting is used, the higher the grade, the greater the ability to dissolve It increases in water, but its water holding capacity decreases for a long time. One of the concentrators High-consumption in the industry are cellulose-based concentrators, commonly called ethers TYLOSE brands are well known in the paint industry. Methyl hydroxy ethyl cellulose or hydroxy ethyl cellulose of grade There are several types of tylos. In a variety of building and powder paints as Concentrators are used. High precision, pigment compatibility and environmental compatibility It is one of its features. Taylor in a variety of industries Pharmaceutical, construction, adhesive, paint paper, etc. are used.
