GCC Filler Loading Calculator
Enter your batch weight and target filler percentage to get the exact quantity of calcium carbonate required, plus bag counts for ordering.
How filler loading is calculated
Filler loading is expressed as a percentage of the total formulation weight. For example, a 1,000 kg batch of interior emulsion paint at 25% filler loading requires 250 kg of GCC. The calculator handles the arithmetic and converts the result into 50 kg and 25 kg bag counts for procurement.
Typical filler loading by industry
Paint and coatings typically use 15 to 35% GCC by weight depending on the grade and PVC (Pigment Volume Concentration) target. Rubber compounds commonly use 30 to 50 phr (parts per hundred rubber). PVC pipes and profiles typically use 20 to 40 phr. The calculator includes industry defaults for each application.
