Zirconium naphthenate

Some polysiloxanes are curable with lead monoxide, with a consequent reduction in both curing time and temperature. High-frequency electrical energy vulcanizes in one case at least. Zirconium naphthenate imparts improved resistance to high temperatures. Barium salts are said to prevent blooming. Sulfur dichloride is also used. Some resins are solidified by pressure vulcanization, using di-f-butyl peroxide. Improvements are to be found in lower condensation temperatures and shorter times of treatment...

Zirconium naphthenate does not impart instability to the emulsion as cobalt naphthenate does. Considering reduction of autoxidation time and emulsion stability, zirconium naphthenate was selected to study catalyst concentration with autoxidation reaction time. Figure 4 represents the effect on reaction time with increasing zirconium naphthenate concentration. After 0.05 grams/1000 grams alkyd III, instability within the emulsion occurs. Therefore, concentrations below 0.05 grams zirconium naphthenate/lOOO grams alkyd should be employed to catalyze the reaction.

Naphthenates of cobalt, manganese, calcium, copper, iron, zinc, and zirconium are used as driers in printing inks. Their use in coatings is declining as a result of the use of higher metal content synthetic driers and the overall trend to latex paint in architectural coatings. 

The rates at which nonconjugated drying oils dry are slow. Metal salts (driers) arc known to catalyze the drying rate. The most widely used are the oil-soluble cobalt, manganese, lead, zirconium, and calcium salts of 2-ethylhexanoic acid or naphthenic acids. See also Paints and Coatings. 

Other catalysts effective in the conversion of isocyanates into carbodiimides include the naphthenates of Mn, Fe, Co, Cu and Pb, derivatives of metallic acetylacetonates, the alkoxides of titanium, zirconium and niobium and vanadium oxides or chlorides. Sterically hindered isocyanates are readily converted into carbodiimides upon heating in the presence of a catalytic amount of a strong base. For example, heating of... 

The zirconium salts of organic acids are widely applied in industry. Carboxylatozirconylic acids are used in treating dermatitis and in making textiles water repellent, while zirconium acetate, Zr(OAc)4, and the trilactozirconate Na2H[Zr(0H)(MeC(0H)C02)3] are components of body deodorants, and the 2-ethylhexanoate and naphthenate are used as siccatives.

The autoxidation reactions are promoted by catalysts which are organic salts of polyvalent heavy metals. By far the most powerful of these are cobalt salts, e.g. cobalt octanoate (2-ethylhexanoate, C4H9CH(C2H5)C00H) or cobalt naphthenate, and these are usually accompanied by other organic salts, e.g. of lead, zirconium or calcium. 

Zirconium driers n. Zirconium salts of various organic acids such as naphthenic or 2-ethyl hexoic. Used as a replacement for lead in fiime-proof paints or other lead-free paints, where equivalent through drying can be obtained. It is also used as an auxiliary drier where color and color retention are important. 

It would be obvious to increase the catalyst concentration in order to further reduce autoxidation time required to densely crosslink the alkyd polymer particles. However, formidable effects arise from increasing the concentration of zirconium maphthenate to 0.05% and cobalt naphthenate to 0.05%. When the emulsion was subjected to 80.0 psi, the autoxidation reaction was uncontrollable. Therefore, the concentration of catalysts is critical.

Lead salts of organic acids, the original driers, function as polymerization catalysts throughout the entire paint film depth in contrast, cobalt salts function as surface driers. Hence, until recently, combinations of lead and cobalt driers have been used to achieve a uniform drying rate. Manganese and zirconium salts may be used in place of lead. Many organic acids have been used to form these heavy metal salts, but the most widely used salts are naphthenates, which are based on naphthionic acid, a residue of petroleum resinous. Other acids used to produce driers are octoic, tallic, rosin, and linolenic acids.
