Chemical properties

Cobalt naphthenate is a flammable brown powder or bluish-red solid; freezing/melting point = 140°C; flash point = 49°C; autoignition temperature = 276°C. Hazard identification (based on NFPA-704 M Rating System): Health 1, flammability 2, reactivity 0. Insoluble in water.

The Uses of Cobalt naphthenate

Cobalt naphthenate is widely used in polyester resins and paint driers. It is used as a curing accelerator, cross linker catalyst for unsaturated polyester resins. It is also used in the production of adhesives, varnishes and waterproofing agents for textiles. Further, it is used as corrosion inhibitors, lubricants, and fuel additives. It plays an important role as oil drying agents.

The Uses of Cobalt naphthenate

Cobalt naphthenate may be used as a catalyst that facilitates the free radical polymerization of (3-methacryloxypropyl)trimethoxysilane (MPS), which can be used to functionalize alumina nanoparticles. It can be used as a promoter for the development of unsaturated flame retardant polyesters.

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.

Air & Water Reactions

Highly flammable.

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.

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.

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.

Flammability and Explosibility

Not classified

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.

Safety Profile

Moderately toxic by ingestion. Flammable when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Cobalt naphthenate is used as a drying agent in paints, varnishes; inks, and for curing plastics.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Medical observation is recommended for 24-48 hours afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray

storage

Color Code—Red: Flammability Hazard: Store ina flammable materials storage area. Prior to working withthis chemical you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area away from strong oxidizers (such aschlorine, bromine, and fluorine). Sources of ignition, suchas smoking and open flames, are prohibited where cobaltnaphthenate is used, handled, or stored in a manner thatcould create a potential fire or explosion hazard
