Nagase America, LLC introduced Denacol EX-622, a crosslinker that provides value-added solutions to many coatings formulation challenges.
Formulators pressed to deliver high-performance coatings can use Denacol EX-622 to fulfill customer needs while imparting additional processing and end-use benefits.
Denacol EX-622 is a sorbitol polyglycidyl ether – its aliphatic epoxy backbone enables formulators to create coatings that are non-yellowing, weather-resistant and low in color. Due to its tetrafunctionality, Denacol EX-622 increases reactivity and crosslink density, resulting in faster cure speeds and better resistance to water staining, chemicals and mechanical wear.
This versatile crosslinker can be used both in traditional epoxy systems and non-isocyanate (NISO) systems. Standard epoxy curatives such as amines can be used with Denacol EX-622 for traditional epoxy systems. For NISO systems, Denacol EX-622 can react with carboxyl functional acrylic resins or specialty curing agents – available from Nagase – to produce high-solids, ambient-cure coatings.
“Denacol EX-622’s unique properties are ideal for indoor or outdoor topcoat applications such as industrial, commercial and architectural flooring, light industrial corrosion protection and agricultural and construction equipment,” says JP Masson, director of sales and marketing. “It also works well in other high-performance applications – such as adhesives – where fast cure speed and high crosslink density are necessary.”
Depending on the application method and requirements, Denacol EX-622 can be formulated with other epoxy materials from the Denacol series to adjust the final properties.
Nagase manufactures the Denacol series of aliphatic epoxies in Japan under strict quality control standards. Denacol EX-622 and related grades are stocked in North America for quick supply.
Nagase will be showcasing Denacol EX-622 and other product offerings at booth 1655 at the American Coatings Show, March 31 to April 2, 2020, in Indianapolis.
