Shanghai Nanzhuo Brand Nano Active Calcium Carbonate GT-301 - High Performance for Paint and Coating Formulations
GT-301 is an advanced transparent nano-active calcium carbonate engineered with a precisely controlled narrow particle size distribution. Through specialized surface treatment using resin acid and surfactants, this product delivers superior performance in offset printing inks, pigment formulations, and related applications. As a highly efficient processing additive, GT-301 significantly enhances ink weather resistance, gloss, and overall print quality, making it an indispensable component for high-end ink manufacturing.
Designed for precision and consistency, GT-301 plays a crucial role in optimizing ink properties, including color adjustment, viscosity control, and concentration refinement. Its exceptional compatibility with various ink systems ensures smooth printability, making it ideal for demanding printing processes where uniformity and durability are critical.
Key Features & Benefits
1. Outstanding Transparency for Superior Ink Clarity
GT-301’s ultra-fine nano-particle structure ensures excellent transparency, making it particularly suitable for light-color inks and high-grade printing applications. Unlike conventional calcium carbonates that may cause opacity or dullness, GT-301 maintains ink clarity while enhancing pigment dispersion. This feature is especially valuable in premium packaging, labels, and artistic prints where color purity is essential.
2. Enhanced Lightfastness & Weather Resistance
One of the standout advantages of GT-301 is its ability to significantly improve ink lightfastness. The advanced surface treatment ensures strong bonding with resin systems, preventing chalking (powdering) and pigment separation. This results in long-lasting print durability, even under prolonged exposure to UV light and harsh environmental conditions. Additionally, its excellent compatibility with base materials minimizes phase separation, ensuring stable ink performance over time.
3. Optimized Dispersion, Permeability & Drying Performance
GT-301 is engineered to provide exceptional dispersibility, ensuring uniform pigment distribution and reducing agglomeration. This leads to smoother ink flow, improved print sharpness, and reduced clogging in fine printing nozzles. Furthermore, its optimized permeability promotes faster drying times, enhancing production efficiency without compromising ink adhesion or finish quality.
4. Stability & Consistency for Reliable Printing Performance
By fine-tuning ink rheology, GT-301 helps maintain optimal viscosity and workability across different printing conditions. Whether used in high-speed offset, gravure, or flexographic printing, this additive ensures consistent ink transfer, minimizing defects such as mottling or uneven laydown. Its ability to regulate ink consistency also reduces waste and improves cost-efficiency in large-scale production.
Applications
GT-301 is widely used in:
Offset & Lithographic Inks – Enhances gloss, reduces dot gain, and improves print fidelity.
Pigment Concentrates – Improves dispersion and color strength in masterbatches.
High-Grade Packaging Inks – Ideal for food, pharmaceutical, and luxury packaging due to its non-yellowing properties.
Publication & Commercial Printing – Ensures vibrant, long-lasting prints for magazines, catalogs, and promotional materials.
Why Choose GT-301?
Precision Engineering – Uniform nano-sized particles for consistent performance.
Surface-Modified Chemistry – Treated for maximum compatibility with resin and solvent systems.
Multifunctional Benefits – Improves gloss, durability, and processing efficiency in a single additive.
Industry-Proven Reliability – Trusted by leading ink manufacturers for high-demand applications.
