Activity of mono- and dizirconyl carboxylates in the presence of cobalt and manganese dryers in the curing of alkyd binders
Abstract
The activity of zirconyl and dizirconyl carboxylates as dryers in combination with cobalt and manganese in the most common types of alkyd binders – fatty alkyd varnish, alkyd-urethane and alkydstyrene lacquers, was studied.
In this purpose, 2-ethylhexanoates of zirconyl and dizirconyl were put in various ratios with primary dryers (2-ethylhexanoates of cobalt and manganese) into varnishes and applied to a glass substrate. Then the drying time and the rate of hardness gain of the obtained films were measured.
It was found out that for all types of binders, the activity of zirconium dryer depends only on the amount of metal introduced into the varnish and, in the case of using 2-ethylhexanoates of zirconyl and dizirconyl, does not depend on the type of zirconium compound used. The optimal molar ratios of cobalt with zirconium (1:2) and manganese with zirconium (1:1) have also been identified, which allow to obtain the maximum drying rate and a set of hardness of alkyd binders.
