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.
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.
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.
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.
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.
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.
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
Notclassified
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.
Moderately toxic by
ingestion. Flammable when exposed to heat
or flame. When heated to decomposition it
emits acrid smoke and irritating fumes.
Cobalt naphthenate is used as a drying agent in paints, varnishes; inks, and for curing plastics.
UN2001 Cobalt naphthenate powder, Hazard Class: 4.1; Labels: 4.1-Flammable solid. UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required
Highly flammable; powder or dust can form an explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
