The Lubrizol Corporation’s Performance Coatings unit announced the commercial availability of a novel flame retardant product, Hycar(R) NH3069, designed to deliver excellent flame retardant performance without the use of additives or halogenated materials. Based on new, self-crosslinking, non-halogen polymer technology, Hycar NH3069 imparts flame retardancy to cellulosics, making it a powerful protective technology for paper, cotton, rayon, glass and mixed fiber media applications.

In addition to flame retardant benefits, Hycar NH3069 offers excellent mechanical performance and improved clarity compared to particulate-filled coatings, the company said. Its inherent thermal stability during processing provides improved color over halogenated polymers. With less additives required, reduced mixing, less chemical inventories and faster clean-up are possible, resulting in higher manufacturing productivity. For filtration applications, Hycar NH3069 provides a lower pressure drop compared to particulate additives.

“This new and unique, halogen-free polymer technology from Lubrizol avoids the need for heavy metals, like antimony trioxide” sayd Gary Anderle, marketing manager. “It’s a game changer for many applications, and we look forward to exploring its full potential by collaborating with formulators to achieve specific flame retardance needs.”

Hycar NH3069 is part of an exciting new platform that will evolve into future flame-retardant products. It can be applied using a broad range of techniques, including knife coatings (J-box), dip and squeeze (padding), foam, gravure, screen printing and rod coating.

Lubrizol’s Performance Coatings unit is a market-driven innovator of specialty chemicals that solve today’s challenges in the paints and coatings, printing and packaging, paper and textiles, plastics and composites, and digital print markets.
