Copper Octoate

Copper Octoate is an anti-fouling agent. it is use in ship bottom paints. Copper Octoate hydrolysis gradually in to copper hydroxide & octoic acid in the presence of seawater, copper hydroxide is an active toxicant. It is use as a rot proofing agent in textile, cordage etc.& to prevent dry rot & mildew grow in timber. Copper may be applied on textile fabrics by dipping, spraying or impregnation. The recommended dosage is 2 % to 2.5 % as metal.

Zinc Octoate

Zinc Octoate reduces rapid film formation and therefore improves through drying. It prevents wrinkling and is used in combination with primary and auxiliary driers. Zinc can be applied as a fungicide and in the formulation of PVC stabilizers.

Manganese Octoate

Manganese Octoate is the second most important primary drier. It can be used as a Cobalt replacement in darker coloured paints where discoloration due to the dark brown Manganese colour is not important. High humidity may however lower the effectivity of Manganese as well. Manganese is also used in combination with Cobalt in the offset printing ink applications.

Lead Octoate

Lead Octoate is used mainly in industrial paint applications. Its use has been limited because of environmental effects. Lead promotes an even through drying and in combination with Calcium and Barium it prevents precipitation of difficult to dissolve Lead compounds. In conjunction with Butyltitanate Lead is used as an accelerator for the hardening of silicon resins.

Cobalt Octoate

Cobalt Octoate is the most active primary drier and is used in conjunction with auxiliary and through drier to promote an even surface through drying. Care needs to be exercised when dosing Cobalt to prevent a too fast drying which would result in surface wrinkling.
