Abstract

Abstract A POLISHING COMPOSITION COMPRISES (A) NATURAL AND/OR SYNTHETIC WAX WITH AN ACID NUMBER OF ABOUT 5 TO 200 OR MIXTURES THEREOF, HAVING A SOLIDIFICATION POINT OF BETWEEN 60 AND 100*C. AND A MIXTURE CONSISTING ESSENTIALLY OF (B) 30 TO 60% BY WEIGHT OF METHYLSILOXANOLS OF A VISCOSITY OF 25 TO 100 CP., AND HAVING AN OH-CONTENT OF NOT MORE THAN 8.8% BY WEIGHT, 10 TO 30% BY WEIGHT OF METHYLSILOXANES CONTAINING SIOMNZ2-GROUPS, WHERE IN, M IS BIVALENT HYDROCARBON WHICH BRIDGES O AND N THROUGH AT LEAST TWO CARBON ATOMS AND WHEREIN Z IS ALKYL, ARYL, THE GROUP -(CH2-CH2-NH)(0-4)-CH2-CH2-NH2 OR -CH2-CH(-Y)-OH OR, PREFERABLY HYDROGEN, 5 TO 15% BY WEIGHT OF AN ORGANIC TIN CATALYST INDUCING HARDENING OF SILICONES AS WELL AS 15 TO 40% BY WEIGHT OF ESTERS OF ALIPHATIC ALCOHOLS OF SILICIC ACID, TITANIC ACID OR ZIRCONIC ACID AND/ OR THEIR PARTIAL HYDROLYSATES AND/OR THEIR CONDENSATION PRODUCTS OR FATTY ACID ACYLATES OF TI OR ZR, IN WHICH THE FATTY ACID HAS A CARBON NUMBER OF AT LEAST 8. THE RATIO OF (A):(B) IS BETWEEN ABOUT 1:4 TO 4:1. THE COMPONENTS (A) AND (B) MAY BE USED IN THE COMPOSITION IN CUSTOMARY CONCENTRATIONS AND MAY BE DISSOLVED IN ORGANIC SOLVENTS OR BE EMULSIFIED IN WATER.
