Monometallic driers for paintwork materials.
One of the principal paintwork materials components, which are hardened according to oxidative polymerization mechanism, are
driers that affect nearly all basic properties of coatings. Drying rate, film hardness and elasticity, impact resistance
and, to considerable extent, protective properties, depend on correct selection and amount of drier.
Driers on the mechanism of action are divided into two classes: primary (true) and auxiliary driers (promoters), which have activating effect on the primary driers. Promoters promote even drying of the coating thickness and increase stability of real driers. Real driers are salts of carboxylic acids, transition metals such as cobalt, manganese, lead, existing in two valent states; promoters include calcium, barium, zinc and zirconium. Mechanism of action of promoters is that being strong bases, they are more actively interact with carboxyl groups of alkyd oligoethers, except for the interaction with salts of metals belonging to the driers. At the same time it is believed that the ions Ca2 reduce activation energy of decomposition of hydroperoxides, i.e. both types of salts have important influence on the final properties of mixed driers.
Driers assortment is rather diverse these days, however as far as consumption is concerned, the leading position is currently being taken by the products based on 2-ethylhexanecarboxylic acid (2-EHC), which possess a number of advantages comparing to traditionally used for synthesis of driers synthetic fatty acids, petroleum acids, fatty acids of tall oil, and other carbon acids. The first of such advantages is stability of composition (commercial acid contains at least 99,5% of base matter) and color grade by Hasen 15 units at most, which permits to obtain concentrated driers of permanent composition with low color grade. This fact is of high importance for light shades paintwork materials, since even small amounts of 64P type melted driers considerably reduce film whiteness.
LLC Arsenal Grupp arranged production of light driers based on 2-ethylhexanoates in Ukraine. We produce 2-ethylhexanoates of monometals - Ņî, Ėn, Zn, Ņā, Âā, Li, Zr, Cu - in the form of solutions in organic solvents (TU U 24.3-32926424-008:2010 and TU U 24.3-32926424-007:2005). Table shows the list of produced monometallic driers and their description in brief.
