Wetting & Dispersing Additives

BYK's wetting and dispersing additives ensure fine, homogeneous distribution of solid particles in liquids and long‑term system stability. They stabilize pigments (inorganic, organic, effect) and fillers in water or any organic solvent — regardless of polarity.

Wetting agents are surface‑active and improve solid wetting. Dispersing agents prevent flocculation through electrostatic or steric effects. Wetting and dispersing additives combine both mechanisms in one product: they wet and stabilize.

Main Functions

Promotes particle wetting and disperses agglomerates into primary particles

Stabilizes primary particles against re-agglomeration

Optimizes the dispersion process and improves efficiency

Reduces slurry viscosity, increases solid content and stability
