China Suppliers Ground Calcium Carbonate (GCC) Factory for Printing Ink - Cost-Effective Filler Solutions
Product Description
Ink-grade ground calcium carbonate, modified with resin acid, enhances ink transparency, gloss, fluidity, and drying properties.
The surface of ink-grade ground calcium carbonate is modified with resin acid, resulting in good compatibility with ink resin. This process can impart extremely high transparency, high gloss, high fluidity, and good drying properties to the ink, and can also improve the gloss and brightness of the ink.
The viscosity of the ink made with this product as filler is moderate, with good printing performance, good stability, smooth prints, and complete dots. The fluidity, transparency and other indicators can be adjusted according to customer needs.
Ultra-fine, ultra-pure ground calcium carbonate enhances ink products with excellent transparency and dispersibility.
Using ground calcium carbonate, which is ultra-fine and ultra-pure. The crystal form and particle size are effectively controlled during the production process. Furthermore, the product surface is modified with resin acid and a special dispersant, resulting in good compatibility with ink resins. Therefore, in ink products, it offers advantages such as small particle size, narrow particle size distribution, good transparency, high gloss, and moderate flowability. It also possesses a three-dimensional structure and excellent dispersibility.
