Calcium Carbonate for Waterborne Interior Paints
If you make waterborne interior paint, buy calcium carbonate for the paint balance you need: opacity, viscosity, application and film properties.
Relia's carbonate candidates can be compared using real particle and absorption data.
- Formulation
- Pigment volume concentration
- Powder
- Distribution and treatment
- Film
- Opacity and required durability tests
Manufacturing Support for This Purchase
Relia manufactures ground, precipitated and selected surface-coated calcium carbonate grades in China through its own factories.
Our calcium carbonate manufacturing focus provides the starting range for this paint enquiry. Send us the binder system, current filler and the optical or application limits that matter. We can discuss the proposed grade and its reporting basis while your paint panels establish the formulation-specific result.

The Paint You Want to Make
An interior-paint enquiry can begin with an 800 mesh entry, a 1250 mesh entry and a finer XM-300 proposal. The labels organise the catalogue, but the trial should compare dispersed particles and the actual paint. We keep coverage, application and the accepted finish together when narrowing the grade.

Carbonate Grades for an Interior-Paint Brief
| Review area | Listed data and acceptance basis | Use in your selection |
|---|---|---|
| 800 mesh · 6537 | The listing states 96% purity for paint and coating filler assessment. Confirm the actual distribution and coarse residue. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| 1250 mesh · 6535 | A 96% purity GCC entry for paper and coating enquiries. Mesh is not a D50 measurement. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| XM-300 · 6003 | The listing gives 1.5 micron average size and D97 3.8 micron, with whiteness 97%. Retain the measurement basis. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| Paint comparison | Set the binder, film thickness, opacity, application and relevant scrub or finish criteria before interpreting filler cost. | Match the stated measurement method and compare the appearance in your finished material. |

A Fair Paint Comparison
Compare the candidates at the intended paint formulation and application conditions. Evaluate dispersed fineness, viscosity, opacity and the required film properties together. A finer catalogue designation can change the mixing and binder-demand discussion; it does not establish a finished-paint improvement on its own.
Mesh shortcuts
Do not establish paint suitability.
Different films
Distort an opacity comparison.
Raw whiteness
Does not replace finished-paint results.
Particle Preparation and Surface Condition
Grinding and classification change the particle population that occupies space in the coating. Finer particles also change the surface that must be wetted, so fineness alone is not a complete buying rule. Connect distribution and absorption data to dispersion, pigment volume and film conditions before drawing conclusions about opacity or usable formulation cost.
GCC: dry and wet routes
Relia uses both dry- and wet-grinding routes for GCC. Grinding and classification are connected to the selected powder's particle specification.
PCC: crystal formation
Relia produces PCC through calcination, slaking and carbonation. The precipitation route forms new particles rather than only grinding the starting mineral.
Selected surface-coated grades
Relia applies surface coating to selected carbonate grades. The actual treatment and intended application remain part of the grade discussion.
Defined carbonate checks
Routine batch checks cover whiteness, moisture and purity. Particle size and oil absorption are checked according to the grade or order requirements.
- Distribution
- Retain average size, D50 and D97 as their actual reported measurements.
- Surface
- Connect a treatment declaration with the application and absorption or wetting evidence.
- Identity
- Keep the selected grade and relevant method with the sample comparison.
A Grade for Repeat Paint Batches
The accepted paint trial becomes the reference for the filler specification. We keep the grade identity and batch information with that proposal. Formulation or processing changes can then be reviewed against a known result.
Connect the Next Purchasing Step
If you formulate wall putty, select calcium carbonate for application feel, water demand, finish and sanding rather than mesh alone.
If you want to use TiO2 more efficiently in white paint, an extender is a trial variable rather than a direct replacement for hiding pigment.
If a high-solids coating becomes too viscous as filler loading rises, compare wetting and particle behaviour in the complete binder system.
