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 naphthenicacids. 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 andmetals act as catalyst to speed up the
oxidative coating. Cobalt is the most useful. It is apowerful
oxidation catalyst and can keep whiteness. Auxiliary metals should
be added to
prevent surface wrinkling after drying. Primary metals which can
replace for cobalt arezirconium, 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 offuels.Rubber Adhesion Promoters ;
Metallic naphthenates, neodecanoates, resinates,boroneodecanoates,
and stearates are widely used in rubber industry especially in the
radialtire 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 aminesare used as catalysts in the production
of rigid, flexible polyurethanes and elastomers.
Unsaturated Polyester Promoters: Cobalt, Potassium, Copper, and
Zinc carboxylates (mainlyoctoates and naphthenates) are used as
initiators/promoters for curing of polyester resins. SALES
