Octoate Driers

This is a clear, nearly colourless high purity liquid drier with an excellent activity and compatibility Calcium Octoate is an important auxiliary drier. It is used in combination with Lead and Cobalt octoate, mainly in alkyd finishes.

Cobalt octoate being the most effective drier promotes polymerization of media, hardens the paint film, improves gloss and water resistance and reduces brittleness of film. The careful use of Cobalt octoate gives the paint film a good gloss, free from frosting tendency. This drier is a universal drier, which is essential in all the media and is capable of performing individually giving reasonable properties to the paint film.

Lead is one of the auxiliary driers also called as through drier. Lead octoate is used as active or top drier. It promotes hard, through drying throughout the entire film and also promotes flexibility.

Manganese Octoate is mainly used in exterior paints, floor finishes, backing enamels and in the paints where colour is not a constraint. The dosage of Cobalt octoate can be minimized by using Manganese Octoate as it is capable of replacing Cobalt because of its high activity.

The absorption of driers in pigments can be reduced by grinding the pigments with Zinc Octoate to retain the drying capacity of the paint media. In the preparation of paints based on high viscosity media which may have only limited solubility in the solvent employed.

Zirconium Octoate is the best replacement of Lead octoate when used in combination with Calcium or Cerium octoate in the lead-free paint systems. Zirconium Octoate shows goods gloss retention and colour retention compared to Lead, but does not perform as well under adverse drying conditions of low temperature and high humidity. Zirconium Octoate is the most useful drier for water resistant finishes due to its stabilizing effect on the ester linkages in the media.
