Calcium Carbonate (CaCO₃) is a naturally occurring mineral derived from high-purity limestone deposits, refined and micronised to engineered particle size ranges for use as a structural pigment extender. In pigment applications, micronised CaCO₃ acts as the...

Common questions about Calcium Carbonate in pigments applications
CaCO₃ acts as a structural pigment extender through particle spacing and packing control (reducing pigment–pigment contact and improving distribution), surface smoothing and optical balancing (promoting uniform particle arrangement), and suspension and rheology support (maintaining paste viscosity and preventing settling) — all without chemically interacting with pigment chemistry.
Its controlled particle size and moderate hardness enable CaCO₃ particles to support pigment suspension in pastes, reduce rapid settling, and help maintain controlled viscosity — essential for handling, storage, and processing stability of pigment pastes and concentrates.
No, CaCO₃'s neutral chemistry ensures full compatibility with both organic and inorganic pigments without altering shade or reactivity. Its high brightness and neutral tone provide a clean extension platform that supports rather than distorts colour development.
Micron Carb 1 Micron is ultrafine for precision pigment spacing in premium concentrates. Micron Carb 9766 offers a balanced PSD optimised for cost-efficient general pigment pastes, delivering predictable dispersion and consistent optical performance across a broader range of pigment systems.
Milcglan brings brightness-driven performance — its engineered particle morphology and superior optical neutrality support clean colour development, making it particularly valuable for premium pigment systems where colour purity, brightness, and consistent shade performance are critical requirements.
