China Suppliers of Ground Calcium Carbonate (GCC) for Printing Ink | Factory Direct Pricing
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.

Frequently Asked Questions
Q
What is ink-grade ground calcium carbonate and how does it benefit printing inks?
Ink-grade ground calcium carbonate is a specially processed mineral filler whose surface is modified with resin acid to ensure excellent compatibility with ink resins. It enhances ink transparency, gloss, fluidity, and drying performance, while also improving the overall brightness and print quality of the final product.
Q
What makes this ground calcium carbonate "ultra-fine" and "ultra-pure"?
The product is produced under tightly controlled conditions that regulate crystal form and particle size throughout the manufacturing process. Combined with surface modification using resin acid and a special dispersant, the result is a product with a very small particle size, narrow particle size distribution, and minimal impurities — meeting the strict purity demands of high-performance ink formulations.
Q
Can the product parameters be customized to meet specific customer requirements?
Yes. Fluidity, transparency, and other key indicators can be adjusted according to customer needs. The professional R&D team is capable of conducting targeted optimization and flexible adjustments of various product parameters, and OEM services are also available to customize specifications and packaging.
Q
What are the key quality specifications of this printing ink-grade calcium carbonate?
