3. Proper dispersion prevents clumping and streaking in the final product.
4. Dispersing agents, or surfactants, help stabilize pigment particles.
5. High-speed mixers and mills are often used to achieve fine dispersion.
6. The quality of dispersion affects the color strength and brightness.
7. Pigment dispersion is crucial in industries like paint, ink, and cosmetics.
8. Water-based and solvent-based dispersions are two main types.
9. Each type of pigment requires specific dispersion techniques.
10. Poor dispersion can lead to issues like sedimentation and flocculation.
