Adhesives & Sealants
Ground calcium carbonate is far more than an economic filler in adhesive and sealant formulations — it is a functional performance booster that enhances mechanical properties, controls rheology, and improves sagging resistance across a wide range of bonding and sealing applications.
Ground calcium carbonate is not only an economic filler but is considered a booster for critical characteristics such as mechanical properties and sagging resistance in adhesive and sealant profiles. The selection of the appropriate grade depends on the desired viscosity, filler loading level, and end-use performance requirements.
Recommended Grades:
| Application Type | Recommended Grades |
|---|---|
| General Purpose Adhesives | M8, M10, M12, M15 |
| Construction Adhesives | M15, M20, M25 |
| Sealants (Silicone, PU, Acrylic) | M8, M10, M12, M15, M20, M25 |
| Tile Adhesives & Grouts | M15, M20, M25 |
| Wood Adhesives | M8, M10, M12 |
Why Calcium Carbonate in Adhesives & Sealants?
- Mechanical Property Enhancement — Increases tensile strength and cohesive strength
- Sagging Resistance — Improves thixotropy for vertical and overhead applications
- Rheology Control — Adjusts viscosity and flow behavior for optimal application
- Volume Extension — Reduces formulation costs by extending expensive polymers and resins
- Dimensional Stability — Reduces shrinkage during curing
- Moisture Resistance — Low moisture absorption maintains bond integrity
- Easy Dispersion — Incorporates smoothly into both water-based and solvent-based systems
