Key Properties
Cobalt Naphthenate is a cobalt-based metal salt commonly used as an accelerator or drying agent in resin and coating systems. It is typically supplied as a purple to dark violet liquid solution in organic solvents. It provides strong catalytic activity in unsaturated polyester resin curing and oxidative drying systems.
Key Features
Cobalt Naphthenate offers fast curing promotion, good compatibility with polyester resins, and stable catalytic performance. It is especially effective when used together with MEKP initiators in unsaturated polyester resin systems. In coatings, it helps accelerate surface drying and improve production efficiency.
Main Applications
Cobalt Naphthenate is widely used as an accelerator for unsaturated polyester resins, fiberglass-reinforced plastics, gel coats, casting resins, and composite materials. It is also used as a drier in alkyd paints, varnishes, industrial coatings, and printing inks.
Production Process
Cobalt Naphthenate is typically produced by reacting cobalt salts with naphthenic acid, followed by dissolution in suitable organic solvents to achieve the required cobalt content and application performance.
