Starch Ethers

STARCH ETHERS

Starch ethers strengthen the consistency of materials which are based on hydraulic binders. Starch ethers influence the rheology behaviour of the binder matrix in water, changing the yield point, flow parameters and water retention for cement-based tile adhesives, renders, gypsum-based plasters and other mixes.

The dosage of starch ethers can be adjusted to reach the desired structural viscosity of the formulation and enable excellent workability. The starch ethers are compatible with other additives, they are chemically inert and do not change the properties of the main binder (cement, gypsum, lime). The starch ethers allow to optimize the economics of the dry mix, facilitating the formulation success at the market.
