Silica Matting Agents | SIOResin®
Two Premium Solutions from SIOResin to Precisely Solve Surface Matting Challenges
How to Choose the Right Silica Matting Agents? In high-end applications such as furniture coatings, printing inks, and food packaging films, a refined matte finish has become a decisive factor in elevating product value and brand perception. Yet many manufacturers share the same frustration: conventional matting agents often deliver uneven matting, leave a gritty surface feel, or even cause whitening and loss of transparency—ultimately undermining product quality and market acceptance.
Thanks to their amorphous, porous microstructure, silica-based matting agents have emerged as the preferred solution for premium matte requirements. As a company dedicated to advanced material innovation, SIOResin in China introduces two self-developed, high-performance silica matting agents H-2625 and H-2593 (HS Code: 2811229000). Both deliver uniform matte effects while preserving surface smoothness and optical clarity. In this article, we break down their core value propositions and selection logic to help you make the right choice.
Why High-End Matting Demands Silica-Based Solutions
When selecting a matting agent, material fundamentals directly define the final appearance and performance. SIOResin’s silica matting agents (powders) are based on an amorphous, highly porous structure, completely free of crystalline phases. This microstructure translates into clear, tangible advantages: high matting efficiency for precise matte or semi-matte control, a smooth and refined surface feel with no sandiness, and exceptional compatibility across coatings, inks, plastics, and films.
Compared with traditional matting agents, silica offers superior purity and structural stability. It preserves the original processing behavior and mechanical integrity of the system while effectively preventing whitening, haze, or optical distortion. For premium products, silica matting agents are not merely an option—they are a necessity. They enhance visual sophistication, tactile refinement, and ultimately, competitive differentiation.
Two Silica Matting Agents from SIOResin, Tailored for Distinct Applications
At SIOResin, we believe that truly good products are designed around real-world applications. Recognizing the differences between thick and thin coating systems, we developed H-2625 and H-2593, each optimized for specific use scenarios while maintaining consistently high performance.
1. H-2625: High Purity, Strong Oil Absorption
Price: USD $5.00/KG Download TDS
H-2625 is engineered specifically for thick-coating applications, with its core strengths lying in exceptional purity and high oil absorption capacity. Featuring a dry-basis silica content exceeding 99%, it contains minimal impurities, significantly improving coating transparency and effectively eliminating whitening issues. With an oil absorption range of 220–280 g/100 g, it delivers strong and durable matting efficiency.
The recommended coating weight is ≥8–10 g/m², making H-2625 particularly suitable for high-end furniture coatings, industrial heavy-duty coatings, and engineering plastics. Feedback from a premium furniture brand confirmed that after switching to H-2625, the matte topcoat achieved uniform appearance and a refined tactile feel, completely resolving previous haze problems. As a result, the product’s premium positioning improved noticeably, with pricing potential increasing by approximately 15%.
In addition, H-2625 demonstrates outstanding thermal stability, with a loss on ignition of ≤5.0%, well above industry averages. Its narrow and uniform particle distribution ensures smooth surfaces without grit, even in thick layers, while leaving mechanical properties uncompromised.
2. H-2593: Ultra-Fine Particle Size, Superior Smoothness — Ideal for Thin Coatings and Films

For thin coatings or film applications, H-2593 is the preferred choice. With an average particle size of ≤3.5 μm, it belongs to the ultra-fine category, allowing excellent dispersion and an exceptionally smooth surface feel in thin layers.
Its optimal coating weight ranges from ≥5–8 g/m², making it particularly well suited for food packaging films, printing inks, and thin industrial coatings. A food packaging manufacturer reported that matte films formulated with H-2593 not only met appearance requirements but also complied fully with food-contact safety standards, thanks to its dry-basis silica content of ≥98.0%.
With an oil absorption of 160–250 g/100 g, H-2593 delivers rapid matting performance even at low addition levels. Its broad compatibility ensures seamless integration with various resin systems without affecting flow behavior or processing efficiency, resulting in smoother production and consistent quality.
A Practical Selection Guide: Match the Product to Your Needs
| Selection Criteria | H-2625 Silica Matting Agent | H-2593 Silica Matting Agent |
|---|---|---|
| Key Strengths | Ultra-high purity, strong oil absorption, optimized for thick coatings | Ultra-fine particle size, superior smoothness, optimized for thin layers |
| Average Particle Size | ≤5.5 μm | ≤3.5 μm |
| Silica Content (Dry Basis) | ≥99.0% | ≥98.0% |
| Oil Absorption | 220–280 g/100 g | 160–250 g/100 g |
| Recommended Coating Weight | ≥8–10 g/m² (thick coatings) | ≥5–8 g/m² (thin coatings / films) |
| Typical Applications | Premium furniture coatings, engineering plastics, industrial thick coatings | Food packaging films, printing inks, thin coatings |
| Selection Rationale | Maximum transparency and strong matting in thick layers | Ultimate smoothness without compromising optical performance |
There is no need to hesitate—simply match the product to your application scenario.
For thick coatings such as premium furniture finishes, engineering plastics, or heavy-duty industrial coatings where high transparency and strong matting are essential, H-2625 is the optimal choice. For thin coatings or films where surface smoothness and light transmittance are critical, H-2593 delivers superior results.
In short: thick coatings—choose H-2625; thin coatings—choose H-2593. Both are designed to eliminate common matting challenges while enhancing overall product quality.
Practical Tips on Use and Storage
To fully unlock the performance of both silica matting agents, attention to detail is essential. The recommended addition level typically ranges from 8–18%, adjustable depending on the desired gloss level. High-speed pre-dispersion is critical to prevent white agglomerates and ensure uniform matting.
For first-time users, laboratory-scale trials are strongly advised before scaling up to production, minimizing operational risks. Always inspect packaging prior to opening to prevent contamination. If the product has been stored for an extended period, confirm that no hard lumps or contamination are present before use.
During handling, appropriate protective equipment—dust masks, gloves, and safety goggles—is recommended. Store products in a dry, well-ventilated environment, and reseal partially used packaging to prevent moisture absorption. Stacking should not exceed ten layers to avoid packaging damage. Long-term exposure to synthetic silica does not cause silicosis; however, prolonged direct skin contact should be avoided.
