QUANXU-DESCRIPTION-1QUANXU SILICA DIOXIDE POWDER (SS-180) M1

SKYSIL SS-180 SILICON DIOXIDE POWDER FOR INK

SS-180 is a high-precision silica matting agent designed for gravure, lithographic, screen printing and special printing inks. With a narrow
particle size distribution (D50) of 4.0-4.5μm and precise oil absorption value control technology, it can achieve excellent matte effect while
significantly optimizing the rheological properties and printability of inks. This product has become an ideal solution for high-resolution printing
scenarios through innovative surface modification processes.
- Precise adaptation of oil absorption value
The oil absorption value (DOP method) of SS-180 is strictly controlled in the range of 260-320g/100g, and the ink performance is enabled
through the following mechanisms:
• Dynamic balance of viscosity: selective adsorption of resin and solvent to avoid sudden changes in system viscosity caused by excessive
oil absorption, ensuring high-speed transferability of gravure inks and leveling of lithographic inks;
• Process compatibility: Adaptable to high-solid solvent-based, water-based and UV inks, excellent compatibility with epoxy and polyurethane
resins, avoiding stratification or granulation.
- Small particle size and high precision advantages
• 4.0-4.5μm fine particle size: Form a uniformly dispersed network in the ink layer to avoid the risk of screen printing blocking, while giving the
coating a delicate touch and high clarity;
• Anti-sedimentation enhancement: Surface hydrophobic modification technology inhibits particle agglomeration, ink storage period > 180 days
without hard precipitation, fluidity retention rate > 97%;
• Drying synergy: Open pores accelerate solvent release, and hot air drying can shorten the drying time by 20%-30%.
- Special printing enhancement
For metal printing, anti-counterfeiting ink and other scenarios, its small particle size characteristics can form micron-level surface textures, improve
wear resistance by 25% (500g/500 tests), and ensure the sharpness of complex pattern edges.
- Application areas
• Gravure/lithographic printing: food-grade matte packaging, book and magazine color pages, scratch resistance increased by 30%;
• Screen printing: electronic product panels, ceramic glaze printing, to achieve high-precision matte effect;
• Special inks: anti-counterfeiting logo, metal substrate printing, to meet stringent requirements such as low migration and weather resistance.
