Unsaturated Polyester Resins

Unsaturated polyester resins are essential to water-resistant finishes used on marine surfaces and other high shine and easy-to-clean fiberglass applications. Cobalt 21 enables cross-linking of polyester resins and has a lower viscosity for optimal performance. Unlike other Cobalt promoters, ours doesn’t require additional agitation prior to use, saving a step and increasing production efficiency.
