Berolan ST 902 is a special starch ether for construction products. It effects a pseudoplasticity
and increases the consistency of the building material. A low adhesiveness to the tools allows a
easy handling of the product. Water retention is controlled by combination with cellulose ether.
Berolan ST 902 is dosed depending on the application in the range from 0,005 to 0,3%.
