COBALT SALTS

Make easy and increase the metallic reticulated structures-rubber bodying.

 

CHARACTERISTICS COBALT NAPHTENATE, COBALT NEODECANOATE and COBALT RESIN BOUNDED are usually used in the tyre and in the belts production to make easy and to increase the metallic reticulated structures rubber bodying. CHEMICAL - PHYSICAL PROPERTIES COBALT NAPHTENATE Chemical character: 10%cobalt naphtenate. Appearance: blue solid. Cobalt content: 10,5±0,5% Softening point: 80-95°C Naphtenic acid: ³80% Acid value: 210-450 Insolubility in heptane: trace Loss at 120°C: £1,5% COBALT NEODECANOATE Chemical character: 20% cobalt neodecanoate Appearance: blue solid. Cobalt content: 20,5±0,5% Softening point: 85-100°C Water content: <4% Molar ratio Acids/Co: 1,62-1,76 Acetic acid: 5,5-7,5% Pentanoic acid: 13-16% Decanoic acid: 56-60% COBALT RESIN BOUNDED Chemical character: 4% cobalt naphtenate. Appearance: blue solid. Cobalt content: 4,5±0,5% Iodine value: max. 100 Softening point: 80-95°C Solubility in heptane: very good Loss at 80°C: max. 2% Insolubility in toluene: max 2% APPLICATION COBALT SALTES are usually added to the mix in rate of 0,5 parts phr expressed as Cobalt metal. The choice between the two salts is in function of the softening point. The COBALT SALTS make easy the bodying not only on the steel but also on the most difficult surfaces as Zinc and Brass. The COBALT SALTS are effective on the natural and on all synthetic rubbers, except for copolymers and ethylen-propylenic terpolymers.
