NITROCELLULOSE
01
Nitrocellulose, Grade C
Industrial-grade cellulose nitrate for coatings and inks.
Applications
Wood lacquers · Printing inks · Leather finishes · Industrial coatings · Adhesive binders
Commercial focus
Low-viscosity nitrocellulose used as a key film-forming and binding component in high-quality flexographic and gravure printing inks.
Main functions in ink formulation
Film-formerStrong, smooth and elastic film after solvent evaporation
BinderHolds pigments and supports color intensity and stability
Rheology modifierAdjusts viscosity and improves ink transfer stability
Print performanceFast drying, adhesion, gloss and printed-layer durability
Application technology
DissolutionSoluble in alcohol and alcohol-ether systems to form the varnish base
Base varnishCombined with plasticizers, resins and stabilizers
PigmentsEnsures excellent pigment wetting and stable dispersion
AdjustmentSupports high-speed printing and uniform ink-layer formation
Advantages
Fast dryingHigher printing speed and reduced energy consumption
Glossy filmBright, sharp and durable print
High adhesionExcellent bonding with BOPP, PET, PE and other films
CompatibilityFlexibility, no cracking and improved durability
