Description

Modified 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.

Modified 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.

Characteristic:

1. Very good fast thickening ability, medium viscosity, certain water retention;

2. Small dosage, the extremely low addition amount can achieve high effect;

3. Improve the material’s own ability to resist sag;

4. It has good lubricating property, can improve the workability of the material and make the operation smoother.

Fields of Application:

Widely used in all kinds of (cement-based, gypsum-based, and grey calcium base) interior and exterior wall putty; all kinds of finish mortar and plaster mortar. Such as gypsum plaster, tile adhesive and masonry mortars.
