-
Resistant to chemical degradation: Ensures stability in aggressive reaction environments.
Light scattering & opacity control
- Smaller GCC particles (1 μm, 2 μm) have a higher surface area, which enhances light scattering and increases opacity.
- This ensures better hiding power, reducing uneven color variations caused by underlying surfaces.
Even pigment dispersion
- Fine GCC particles (1 μm, 2 μm) act as a spacer between pigment particles, preventing agglomeration (clumping).
- This ensures uniform pigment distribution, leading to consistent color tone throughout the coating.
Viscosity & application control
- Medium-sized particles (5 μm) optimize the rheology (flow behavior), preventing color streaks or patchy appearance during application.
- Better viscosity control ensures the paint spreads evenly, reducing fluctuations in color intensity.
Matte vs. gloss effects
- Smaller particles (1 μm, 2 μm) contribute to a smoother surface, leading to higher gloss finishes.
- Larger particles (5 μm) increase diffuse reflection, which can create a matte effect when required.
The right combination of 1 μm, 2 μm, and 5 μm GCC grades ensures that coatings have uniform opacity, smooth application, and consistent color across surfaces, minimizing defects like streaks, patchiness, or gloss inconsistencies.
