THYON™ acrylic resins: A safer, sustainable path beyond nitrocellulose

THYON™ developed by Diransa offers a next-generation solution that preserves the speed and brilliance of solvent-based inks while eliminating the drawbacks of nitrocellulose.

Introducing the THYON™ Series

It’s important to identify specific products which can be implemented in today’s ink formulations. THYON™ represents a family of solid acrylic resins engineered specifically to replace nitrocellulose in solvent-based flexographic and gravure inks. They dissolve completely in alcohol or alcohol/ester blends, providing equivalent or superior press behavior to NC without explosive hazard or high-VOC burden.

The SR grades provide the backbone for pigment dispersions and surface or lamination inks, while OX787 acts as a co-resin to enhance adhesion and gloss. Together, they form a unified platform capable of replacing NC in virtually every solvent-based packaging ink.

Printability and gloss: Performance beyond nitrocellulose

Laboratory tests comparing THYON™ acrylic resins with standard 27 %-solids NC inks show a nearly identical viscosity profile but superior optical performance.

In lab testing, THYON™ based inks exhibited 30–60 % higher gloss than their NC counterparts while maintaining full adhesion and scratch resistance. They also allow greater pigment loading with white inks containing up to 45 % TiO₂ retain both flexibility and brightness. This efficiency let converters achieve equal opacity with thinner films, cutting overall ink consumption.
