Abstract
Described herein is a pigmented composition which is suitable for coating components in an in-mold coating process, a process for coating components, and a method of using the composition for improving the flow behavior of compositions used for producing components. The composition includes at least one solvent L, at least one alkoxylated fatty acid and/or fatty alcohol, at least one alkoxylated polysiloxane, and at least one color base BF.
Claims20
A pigmented composition, comprising
- (a) at least one solvent L,
- (b) at least one compound of the general formula (I)
- R1—(C═O)r—O-(AO)s—R2 (I)
- in which R1 is a saturated or unsaturated, aliphatic hydrocarbon radical having 6 to 30 carbon atoms,
- R2 is H, a PO(OH)2 radical, or the optionally partially phosphated radical of a monosaccharide or disaccharide, or the optionally partially phosphated radical of an alditol,
- AO stands for one or more alkylene oxide radicals selected from the group consisting of ethylene oxide, propylene oxide and butylene oxide,
- r is 0 or 1, and s is 0 to 30;
- (c) optionally at least one polyether-modified alkylpolysiloxane,
- (d) at least one polysiloxane of the general formula (II)
- R3—Si(R4)2[O—Si(R4)(R5)]a—[O—Si(R4)2]b—O—Si(R4)2—R3 (II),
- in which
- R3 and R4, in each case independently of one another, are a methyl group or a (HO—CH2)2—C(CH2—CH3)—CH2—O—(CH2)3—* radical,
- R5 is a methyl group,
- a is 0 or 1 to 10, and
- b is 3 to 30;
- (e) at least one color base BF, and
- (f) optionally at least one binder B.
