Wetting and Dispersing Additives
Wetting and Dispersing Additives are surfactants used to facilitate the dispersion of pigments. They serve several functions, including reducing dispersion time and energy, stabilizing pigment dispersions, modifying pigment surface properties, and adjusting their mobility. Dispersants offer numerous benefits such as improving gloss, preventing color separation, enhancing color intensity, reducing viscosity, and increasing pigment concentration. They also help minimize clumping, improve storage stability, and enhance color spread, saturation, transparency (for organic pigments), or coverage (for inorganic pigments).
Dispersants work by absorbing onto solid particle surfaces, promoting wetting, forming a polymer adsorption layer to increase surface charge and create barriers between particles, and establishing a bimolecular layer structure that encourages electrostatic repulsion and uniform dispersion. By using dispersants, solid particles can be stably dispersed in liquid mediums, maintaining consistent physical and chemical properties throughout the system. Camen Chemicals offers effective dispersants that ensure reliable and stable dispersion, benefiting paint formulations and achieving desired coating properties.
