Claim 0:
1. A manual process for injection molding of coated components, the process comprising the following steps in the order indicated:
(A) applying a release agent composition to at least one inside of at least one molding part of a closable molding tool,
(B) flashing the release agent composition applied in step (A),
(C) optionally inserting at least one material M1 and heating of the molding tool,
(D) applying a composition Z1 into the opened molding tool,
(E) manually closing the molding tool,
(F) crosslinking the release agent composition and also the composition Z1 applied in process step (D),
(G) optionally applying at least one further composition Z2 and crosslinking the composition(s),
(H) manually opening the molding tool,
(I) manually removing the molded coated component, and
(J) optionally aftertreating the molded coated component, wherein the release agent composition comprises:
(a) at least one solvent L,
(b) at least one compound of the general formula (I)

R1—(C═O)t—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; and
(e) optionally at least one binder B.
