Usage

Fire Hazard

Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.

Air & Water Reactions

Highly flammable.

Chemical Properties

Black liquid

Reactivity Profile

COBALT NAPHTHENATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

General Description

Cobalt naphthenate is a brown powder or a bluish-red solid. Cobalt naphthenate is easily ignited and once ignited can burn profusely. Cobalt naphthenate is used to make paints and varnish.

Health Hazard

Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Contact allergens

Cobalt naphthenate is made by treating cobalt hydroxide or acetate with naphthenic acid. It is an accelerant in rubber, unsaturated polyester, and vinyl ester resins.
