Methyl Hydroxy Ethyl Cellulose
CheSiloTM Methyl Hydroxy Ethyl Cellulose
CheSilo Methyl Hydroxy Ethyl Cellulose（abbr. CheSilo MEC） is a non-ionic, odorless water-soluble cellulose ether. It is widely used as water retainer, thickener, bonding and adhesion agents, protective colloid, stabilizer, and suspending aids in industrial and construction applications etc..CheSilo MEC has better performance on high temperature situation than CheSilo MPC so it is more popular with exterior wall finish plaster and gypsum.

Note:
1.CheSilo MEC consists of pure grades and modified grades providing special properties for detailed application.
2.The viscosity is based on Brookfield RV,20rpm at 20℃ in 2% aqueous solution.
3. MEC 300(S) means two grades:MEC 300 or MEC 300S(same viscosity with delayed solubility)
Typical application of CheSilo MEC:
Tile adhesive
Tile grout,Joints and Crack Fillers
Gypsum Manual Plaster
Exterior Insulation and Finish System(EIFS)
Self-leveling Compound
Water-borne paint
Package and storage
The products are supplied in multiply paper bags with polyethylene inner liner, with the net weight of 25KG.
The product should be stored under dry and clean conditions in its original packing and away from heat. The product is hygroscopic. The packaging is selected in a way to avoid ingress of moisture, but the water content of the packed product will/may increase if not stored dry.
