Description
Fettsäuren, die nach der Bildung des Makromoleküls mit ungesättigten Fettsäuren der Kettenlänge von Q0 bis C18 umgesetzt wurden. Der Aufbau der genannten elektroneutralen Salze (B) wird in den deutschen Patentschriften 1157 326 und 1 157 327 beschrieben. Die Gesamtmenge des Additivs (A) und (B) hängt selbstverständlich von Fall zu Fall von der Pigmentart und der Zusammensetzung des Bindemittels ab. Auch das Dispergierverfahren und die hierfür verwendeten Maschinen sind für die genaue Festlegung innerhalb der genannten Grenzen bestimmend und können vom Fachmann leicht ermittelt werden.Fatty acids which, after the formation of the macromolecule, have been reacted with unsaturated fatty acids with a chain length from Q 0 to C 18. The structure of the aforementioned electrically neutral salts (B) is described in German patents 1157,326 and 1,157,327. The total amount of the additives (A) and (B) depends of course on the case-by-case on the type of pigment and the composition of the binder. The dispersing process and the machines used for this are also decisive for the precise definition within the stated limits and can easily be determined by the person skilled in the art.

It has been found that low-viscosity dispersibility properties are found in many technically important applications of transparent iron oxide pigments in fertilizers. Since the 40 alkyd resin solutions available on the market are obtained when the pigments of this type are usually very finely divided, they are a combination of anions in agglomerates, which are very difficult to find in binding-active wetting agents (A), consisting of salts can be distributed by media systems. Since the primary, secondary, tertiary amines, alkylol divisibility in order to achieve the best possible op- amines or ammonia with alkyl, cycloalkyl or timal grain distribution with conventional dispersible 45 aralkyl sulfonic acids with at least 5 carbon yeast methods, z.

Such iron oxide concentrates are composed of one another in a weight ratio of 1: 0.5 to bind the processor himself to deal with the problem 1:10 and to carry out their total amount, based on the mechanical fine division. Rather, the pigment used can be between 5 and 15%. The HLB value used for the above-mentioned concentrates without an additional range of anion-active wetting agents in terms of dispersing work in the system to be colored is approximately 9 to 14.
