• R1—Si(CH3)2—Z
• wherein:
• R1 is a branched monovalent hydrocarbon group of from 5 to 8 carbon atoms containing at least two methyl groups;
• Z is R2 or R3;
• R2 is CH2CH2CH2—O—(—C2H4—O)a(C3H6O)b(C4H8O)c—R4 in which R4 is hydrogen, a linear or branched monovalent hydrocarbon group of from 1 to about 4 carbon atoms or an acyl group, subscript a is from 1 to about 20, subscript b is from 0 to about 19, subscript c is from 0 to about 19 and the sum of subscripts a, b and c is from 1 to about 20;
