Starch Ether
Michem starch ether is a kind of chemical modified starch without plasticizer and organic solvent. Its appearance is white powder. Compared with other materials, it has good compatibility.
Product Description
Michem starch ether is compatible with other buildings admixtures, especially suitable for construction dry mix such as mortar, adhesive, and plaster. Combined together with methyl cellulose in the building dry mix, they can realize higher thickening, stronger structure, sag resistance and workability. The viscosity of mortars, binders, and plasters containing higher methyl cellulose ethers can be reduced by the addition of starch ethers.
