Coatings & Inks
DuPont Global Specialty Solutions (GSS) is a business of DuPont Nutrition & Biosciences, fully dedicated to serving industrial markets.
GSS offers METHOCEL™, WALOCEL™ CRT and ETHOCEL™ cellulose ethers, Lattice® NTC microcrystalline cellulose, POLYOX™ water-soluble resins and Scogin® alginates. Those products provide unique properties in coatings, paints and printing inks.
GSS supports its customers around the world to develop, optimize, and manufacture a diverse range of coatings, paints and inks products.
Coatings & Paints Applications
In water-based paints, a typical functionality of our METHOCEL™ cellulose ethers and POLYOX™ water-soluble resins is to control viscosity and rheology. In addition, METHOCEL™ and POLYOX™ ensure a uniform application, film coalescence and adhesion to the substrate.
ETHOCEL™ ethylcellulose provides similar benefits in solvent-based paints:
- Rheology modification
- Suspension
- Uniform application, smooth finish
- Durability
In water-based paints and coatings, Lattice® NTC colloidal microcrystalline cellulose improves the stability and homogeneity of paints. It improves leveling and sagging at the same time. Lattice® NTC is natural and is a green chemistry alternative to non-renewable chemicals.

Printing Inks
Our most-widely used polymer for printing ink applications is WALSRODER™ Nitrocellulose. For more information on our Nitrocellulose offering, please consult our WALSRODER™ webpage.
DuPont Global Specialty Solutions also offers ETHOCEL™ ethylcellulose, used as a high-quality rheology modifier, film former and binder for solvent-based printing inks. ETHOCEL™ is currently used in various printing processes, such as gravure, flexography and screen printing.
Additionally, ETHOCEL™ ethylcellulose polymers act as wetting agents during the pigment grinding process to ensure that pigments and dyes stay dispersed.
POLYOX™ WSR and METHOCEL™ are also used as rheology modifiers, stabilizers and film formers which contribute to improved gloss and adhesion, in water-based systems.
DuPont’s product range helps our printing inks customers and their products with:
- Film formation
- Rheology modification
- Tunable viscosity
- Pigment and dye dispersion
- Improved adhesion and gloss
- Robust formulations with proven performance
- Versatility: can be used in most printing processes
