Monometallic driers for paintwork materials. Production and sale in Ukraine.
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 paint-and-varnish coatings. Drying rate, film hardness and elasticity, impact resistance and, to considerable extent, protective properties, depend on correct selection and amount of a drier.
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 possesses a number of advantages comparing to traditionally used for synthesis of driers synthetic fatty acids, petroleum acids, fatty acids of tall oil, and other carboxylic 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 molten drier considerably reduce film whiteness.
The company produces 2-ethylhexanoates of monometals - Ņî, Ėn, Zn, Ņā, Âā, Đb, Zr, Ņu, Li - in the form of solutions in organic solvents (TU U 24.3-32926424-003:2005 and TU U 24.3-32926424-007:2005). Table 1 shows the list of produced monometallic driers and their description in brief.
