LEAD OCTOATE

Lead octoate is the important auxiliary drier especially in applications where drying is required at low temperatures (less than 10 degree C). Metallic carboxylates, metal salts of carboxylic acids, have industrial applications in: drier or additive for paints, coatings and inks. Driers are substances put into paint to make dry quickly. They are metallic salts of low molecular weight fatty acids or naphthenic acids.

Detailed Description for LEAD OCTOATE

Metallic carboxylates, metal salts of carboxylic acids, have industrial applications in;

Drier/Additive for paints, coatings and inks; Driers are substances put into paint to make dry quickly. They are metallic salts of low-molecular-weight (chiefly C8) fatty acids or naphthenic acids. Naphthenic acid is a complex of carboxylic acids( various low-molecular-weight fatty acids believed to have cyclopentane ring mainly). Hydrocarbon parts take oxygen in air and metals act as catalyst to speed up the oxidative coating. Cobalt is the most useful. It is a powerful oxidation catalyst and can keep whiteness. Auxiliary metals should be added to prevent surface wrinkling after drying. Primary metals which can replace for cobalt are zirconium, lead, cerium and iron and auxiliary metals are like calcium, manganese, barium, zinc, lithium.

 

Catalyst for chemical reactions (polymerization, esterification, oxidation, condensation, hydrogenation and other reactions) and catalystic special applications in lubricant and grease additives, fuel combustion additives to enhance and stabilize the performance of fuels.

 

Rubber Adhesion Promoters ; Metallic naphthenates, neodecanoates, resinates, boroneodecanoates, and stearates are widely used in rubber industry especially in the radial tire industry to promote adhesion between the rubber wire coat compound and the brass-coated steel belt. Cobalt carboxylates are most widely used.

 

Polyurethane catalysts: Tin, bismuth, mercury, zinc carboxylates and their blends with amines are used as catalysts in the production of rigid, flexible polyurethanes  and elastomers.

 

Unsaturated Polyester Promoters: Cobalt, Potassium, Copper, and Zinc carboxylates (mainly octoates and naphthenates) are used as initiators/promoters for curing of polyester resins.
