Working in close contact with the consumers of our monometallic driers, we soon realized that it was not always convenient for the end consumer to deal with them, i.e. prepare a mixture of driers yourself. Therefore, along with single-metal ones, we have developed a number of formulations of polymetallic (mixed) desiccants, which are based on 2-ethylhexanoates of driers agent metals (cobalt, manganese) and various promoters. It should be emphasized that they all do not contain lead compounds.

Typically, the amount of desiccant introduced into the paintwork is calculated based on the ratio of active metal to film former, as it is known that the effect of the desiccant in the film-forming system depends to a large extent on its quantity.
It has been experimentally established that for drying the alkyd varnish PF-060 it is necessary to use 60-70% (counting on metal) less mixed octoate desiccants than desiccant 64P (DLCK), and the hardness of the cured coating in the first case is 10-15% higher.
The hardness of the coating based on varnish PF-060 with the addition of various desiccants is shown in the table below. The drying time to degree 3 at a temperature of 20±2 °C in all cases was 24 hours.

The results obtained indicate that the mixed desiccants of ARSENAL GROUP LLC, containing the optimal mixture of metals, successfully replace highly toxic lead-containing desiccants in polycondensation coatings. All mixed desiccants are less toxic and significantly lighter (color on the iodometric scale when diluted with white spirit 1:20 no more than 20 mg J 2 / 100 cm 3 ) than traditional ones. Their introduction into light-colored enamels does not lead to a change in hue.

When studying the properties of synthesized driers agent, the effectiveness of calcium, zinc, and barium octoates as dispersants was tested. For this purpose, 0.5 parts (by weight) of ArdoS -04, ArdoS -03 and ArdoS -05 mark A and after the same dispersion time in a bead mill, the degree of dispersion was determined. The test results of the dispersing properties of Ca, Zn, Ba octoates are given in the table.

From the test table data on the dispersing properties of calcium octoate, zinc, barium, it follows that all tested desiccants have a positive effect on the dispersion speed, but calcium 2-ethylhexanoate has the best dispersing properties (ArdoS-04).
Considering that, according to the literature, Ca 2+ ions reduce the cobalt activation energy, the use of calcium octoate is highly desirable. To confirm this, we determined the hardness of coatings based on PF-115 white enamel with the addition of various desiccants. The drying time to degree 3 at a temperature of 20(±2)°C in all cases was 24 hours. The results of comparative tests are given in the table of comparative tests of driers in enamel PF-115 white (see below).

We also studied the dispersion efficiency of calcium octoate compared to soya lecithin in the manufacture of white and green PF-115 enamels (see figure). The figure shows that the dispersion of pigments in the initial period (15-20 minutes) proceeds almost the same for all systems. With further dispersion, pigment pastes containing calcium octoate reach a milling degree of 25 μm after 30 minutes, and those containing lecithin only after 45-50 minutes. Without the use of a dispersant, a dispersion time of up to 25 microns is 65-70 minutes. Thus, the use of calcium octoate in an amount of 0.5-0.6 parts (by weight) per 100 parts of pigment paste reduces the dispersion time by 40-50%.

Thus, the studies showed that the use of 2-ethylhexanecarboxylic acid to obtain desiccants allows:
– eliminate lead from desiccant formulations;
– reduce the amount of active metals introduced into film-forming systems;
– improve the quality of coatings based on coatings with these driers agent;
– to intensify the process of dispersing pigments e).
