LignoSphere’s patented process transforms lignin into stable, water-dispersible colloidal particles with highly functional surface properties. These spherical particles enable high-performance coatings and adhesives while maintaining scalability and cost competitiveness, replacing fossil carbon in the formulation.
LignoSpheres are colloidal lignin particles suitable for coatings, adhesives, and advanced material systems. Unlike raw lignin, these engineered particles offer a high surface-area-to-volume ratio, controlled morphology, process compatibility, and consistent performance batch to batch — enabling industrial applications for one of the world’s most underutilized natural polymers.
WORKING WITH OUR COLLOIDAL LIGNIN PARTICLES
PARTICLE DATA
Mean particle diameter: 450 nm
Surface charge: Anionic
Stability range: pH 3-8
Form: Dry powder
Compatible system: Water-based, epoxy
Redispersion: Shear, dissolver blade or homogeniser
LignoSpheres are spherical particles of unmodified kraft lignin, supplied as a dry powder. Mean particle diameter is 450 nm, with an anionic surface charge that keeps the particles dispersed in water at pH 4–5.
They are stable across pH 3–8 and compatible with water-based and epoxy systems. Redispersing the powder requires shear, a dissolver blade or homogeniser. In epoxy systems the particles disperse in the resin itself, so full redispersion is not always necessary.
The main formulation consideration is pH: matching the dispersion to the system it enters avoids most compatibility issues. Cationic compounds and high organic solvent content both reduce stability.
