Kulucote 2
Kulucote 2 is a premium, ultra-fine, surface-treated calcium carbonate powder used primarily as a performance-enhancing agent in the paints and plastics industries.
Industrial Applications
According to Idwala Carbonates, the Kulucote range consists of “floated” calcium carbonates coated with stearic acid to ensure excellent dispersion.
Paint and Coatings: It acts as a premium extender to improve opacity, whiteness, and durability. Experts at Hippo Industrial Minerals highlight its use in high-end decorative paints and specialty wall coatings like Gamazine.
Plastics and Polymers: It is used in high-end plastics to enhance mechanical properties such as rigidity (stiffness), impact resistance, and surface finish.
Ink Manufacturing: The fine particle size (approximately 2.3 µm) and coating make it suitable for use in the ink industry to maintain consistent dispersion and quality.
Film Production: Producers like Omya Idwala SA indicate it is used in blown film and breathable film applications (such as baby diaper back-sheets) to improve thermal conductivity and control moisture breathability.
Key Performance Benefits
As detailed by industrial mineral suppliers:
Cost Efficiency: It serves as an inexpensive filler that can partially replace more expensive pigments like titanium dioxide while increasing the bulk of the product.
Improved Processing: Its hydrophobic (water-repellent) stearic acid coating allows for better mixing into polymer matrices, which can increase production output by improving thermal efficiency during cooling.
Durability: By reinforcing the structure of the final material, it helps products withstand environmental wear, especially in exterior paint and construction materials.
