VARNISHES AND MOLDING MATERIALS WITH A CONTINUOUS CONTENT AND INCREASING SLIDINESS OF SILOXANES AND THE USE OF SUCH SILOXANES AS ADDITIVES FOR LACQUERING AND MOLDING MATERIALS

摘要

Coating compositions and molding materials containing a polyester group containing siloxane to enhance spreading and increase lubricity, having the formula IMAGE I wherein R1 represents alkyl groups with 1 to 30 carbon atoms which may be replaced partially by other groups, A and B each represent -CH3 or R2-Z-, R2 represents an aliphatic and/or cycloaliphatic and/or aromatic polyester group free of Zerewittinoff H atoms, having an average molecular weight of 200 to 3000, and containing at least three IMAGE groups, Z represents a divalent group connecting the silicon atom with the R2 group, x is 3 to 250, y is 0 to 50, and in which the average molecule contains at least one R2-Z- group and the ratio of the number of R2-Z- groups to x is 1:2 to 1:40.
