Zinc Octoate

Listing ID #3597842

Zinc Octoate is an auxiliary drier used as a pigments dispersing agent. The pigment such as titanium dioxide and carbon black has the tendency to absorb driers which reduces loss or effect of drying rate.
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. The preparation of paints based on high viscosity media which may have only limited solubility in the solvent employed, Zinc Octoate should be used before the addition of pigment as well as other drier combinations. Zinc Octoate prevents the paint film from webbing and frosting effects. The uses of Zinc Octoate is not suggested with dehydrated castor oil media and tong oil media because these driers may produce bloom and reduce gloss of the film.
