INK COATING-2

Under the high-tech printing progress, the balance between matte effect and high transparency is the biggest challenge. SKYSIL SS-230

silica matting agent can solve this problems with its high purity SiO2 content and good performed particle size dispersion.

SS-230 not only can provide even and low matte effect but also keep the clarity of the printing ink. This makes it an ideal choice for applications

with stringent visual requirements, such as matte PET labels and high-end gift boxes.

What are the main chemical datas of SS-230?

SKYSIL SS-230 is a high-purity synthetic silica matting agent specifically designed for high-performance printing inks. The following key parameters

ensure its process stability and excellent optical properties:

- Purity and Optical Properties: SiO₂ content ≥99%, whiteness ≥93.0 (ensuring no yellowing on white substrates).

- Matting Efficiency: Oil absorption 180-220 ml/100g, porosity ≥1.3 ml/g, particle size (D50) 3.5-4.0 μm.

- System Compatibility: pH 6.0-7.0 (compatible with acidic/basic resins), loss on drying ≤5.0%, loss on ignition ≤6.0% (reducing defects).

How can SS-230 enhance a more stable printing ink's formulation?

Introducing new matting agents can impact production. SKYSIL SS-230 is designed for seamless integration, minimizing formulation adjustments.

Its neutral pH (6-7) ensures broad compatibility with a variety of resins, while its controlled oil absorption (180-220 ml/100g) facilitates precise viscosity

management. More importantly, its low loss on ignition (≤6.0%) means less volatile matter, reducing the risk of bubble defects and ensuring consistent

film quality during high-speed printing.
