1003 CALCIUM CARBONATE 3 MICRON
High-purity ultrafine calcium carbonate for superior performance
Cemix 1003 Calcium Carbonate 3 Micron – Uncoated delivers exceptional performance, versatility, and cost savings.
Benefits & Features
Non-reactive surface for neutral compatibility: Ideal for water-based systems and formulations where surface coatings are unnecessary or undesirable.
Superior dispersibility in aqueous systems: Ensures smooth blending and easy integration in paints, sealants, and adhesives without affecting rheology profiles.
Eco-friendly and additive-free: Free of surface treatments or coatings, making it suitable for eco-sensitive applications or further downstream modification.
Lower material cost for non-reactive applications: Offers cost-effective functionality in formulations not requiring surface-treated fillers.
Area Of Use
- Water-based paints & coatings – offers excellent dispersibility and opacity without surfactant interference, making it ideal for eco-friendly and sensitive formulations.
- Construction adhesives & sealants – provides bulk, mechanical reinforcement, and smooth consistency, ensuring better application and long-term performance.
- Plasticized PVC – reduces costs, improves mechanical properties, enhances surface smoothness, and increases opacity in flexible PVC products.
- Rigid PVC profiles & extrusions – maintains dimensional control and stiffness in non-coated systems; improves extrusion speed, thermal conductivity, and melt flow.
- PVC coatings – contributes to abrasion resistance and tensile strength, improves gloss, opacity, and application smoothness.
- Polyurethane systems – replaces part of the expensive PU raw materials; enhances tensile strength, hardness, abrasion resistance, and dimensional stability.
- Calendered sheets, molding & cables – improves rigidity, compression strength, and hardness; increases thermal conductivity, tear resistance, and durability.
- Polyolefin compounds – enhances modulus of elasticity, improves extrusion and injection molding performance, and boosts whiteness, opacity, and gloss.
- Uncoated paper & board production – contributes to brightness and bulk in paperboard fillers, enabling cost-effective opacity enhancement.
- Plaster & putty compounds – provides whiteness, bulk, and workability without added hydrophobicity, ensuring smooth application and drying behavior.
- Rubber applications – enhances tensile strength, modulus, tear resistance, and abrasion resistance; adds stiffness and dimensional stability.
- Advanced paint manufacturing – functions as a high-performance extender pigment and rheology modifier, contributing to flow and consistency control.
