Cobalt Octoate

Cobalt is an extremely active & most widely used drier in coatings & capable of being used even as a single Drier.
It is primarily an oxidation catalyst & acts as a " Surface Drier ". It may have a tendency to cause surface wrinkling,
hence to provide uniform drying. Cobalt is generally used in combination with other metals, such as Manganese,
Zirconium, Calcium & Combinations of these metals.
As quantity of Cobalt Drier used is very small, it minimizes discoloration in paints & enamels as compared with other
Driers. Cobalt does not discolor white paints as the deep blue color of the cobalt counteracts the yellow of the oils &
resins & thereby enhances the whiteness of the paint. The unique feature of cobalt is that it is least affected by atmospheric humidity. Cobalt is an effective accelerator for polyester.

Manganese Octoate

Manganese driers are intermediate in activity & they have both oxidizing & polymerizing properties. When manganese
used alone it may produce too hard & too brittle films. When used in combination with Lead, hard tough & durable
films are produced.

One disadvantage in use of manganese driers is their relative dark color, which has a tendency to discolor white
or light finishes.

Lead Octoate

Lead is a through drier & is always used with cobalt &/or manganese. Lead drier improves the drying time of
double boiled linseed oil & yields very pale & clear boiled oil.
Lead in combination with cobalt & calcium are suggested, particularly for long oil alkyds lead is the most
important drier. However some of the problems connected with lead driers such as sulpher staining &
reaction with polybasic acids are overcome by inclusion of calcium drier. As lead is toxic in nature its
usage in toys & edible film packaging is to be avoided.

Calcium Octoate

Calcium being an auxiliary drier, has little drying action in itself but is very useful in combination with active driers.
In vehicles that show poor tolerance for lead, calcium can replace part of the lead with a larger amount of calcium
to prevent the precipitation of the lead & maintain drying effeciency. Calcium is also useful as pigment wetting &
dispersing agents & help to improve hardness & gloss & reduce "Silkins". When ground with drier adsorbing pigments, Calcium minimizes loss of dry by being preferentially absorbed.

Zinc Octoate

Zinc being an auxiliary drier, used in conjunction with redox metals. The primary function of zinc is to keep the
film "Open" by retarding Surface dry, thus permitting hardening through out & preventing surface wrinkling, particularly in Cobalt containing films & enamels. Zinc is a powerful wetting & dispersing agent, & when incorporated early in formulation, it greatly reduces the time of mixing & grinding. Because of the extremely light colour, Zinc can be added without discoloring the film.

Zirconium Octoate

Zirconium is a most useful & efficient auxiliary drier. Zirconium like lead serves as a through drier & is generally used in combination with Cobalt, Manganese & Calcium. Unlike Lead, Zirconium is a poor pigment wetting & dispersing agnet.
Zirconium is an active cross-linking agent & as such improves hardness of stoved films as well as their adhesions.

Zirconium is not as effective in phenolic resin based media it is recommended as a catalyst for epscy esters. Use
of Lead driers in combination with Zirconium is to be avoided totally.

Copper Octoate

Copper is an anti fouling agent. It is used in ship bottoms paints. Copper Octoate Hydrolyses gradually in to Copper Hydroxide & Octoic Acid in the presence of seawater, Copper Hydroxide is an active toxicant.

It is used as a rot proofing agent in textiles, cordage etc. & to prevent dry rot & mildew growth in timber, its insecticidal property is taken advantage of import a long lasting protection against termites, beetle & ambrosia
& many other insects attacking timber/lumber, Copper may be applied on textile fabrics by dipping,
spraying or impregnation. The recommended dosage is 2% to 2.5% as metal.

Iron Octoate

Iron is used backing finishes since it promotes rapid drying by polymersisatoin. It is an excellent wetting agent
for Carbon black & iron oxide. It prevents adsorption of driers on the surface of the pigment & increases gloss.
In air dry finishes it is useful in eliminating film tackiness of paints containing a high percentage of non drying oil component such as fish oil.
