Bio-based Silica Matting Powder

Core Features

1. Excellent Matting Performance

   With a unique porous structure and reasonable particle size distribution, the powder can effectively scatter incident light to achieve high matting efficiency. It can adjust the product gloss to different levels such as full matte and semi-matte according to requirements. The matting effect is uniform and stable, without affecting the transparency and mechanical properties of the substrate.
2. Environmental Sustainability

   Derived from renewable biomass such as plant straw, bagasse and rice husk, it features low carbon emissions during production. The product is biodegradable or recyclable in nature, complying with international environmental standards such as EU REACH and US FDA, and meeting the downstream industry's demand for green and eco-friendly materials.
3. Good Compatibility and Dispersibility

   The surface can be modified organically, enabling good compatibility with water-based, oil-based and solvent-free systems. It can be dispersed without special equipment, is not easy to agglomerate, and can significantly improve the application performance and storage stability of coatings and inks.
4. Additional Functional Advantages

   In addition to matting, it can enhance the wear resistance, scratch resistance and weather resistance of the substrate. It also has certain oil absorption and anti-blocking properties, improving the overall quality of the final product.

Technical Parameters (Typical Values)

Application Fields

1. Coatings Industry: Used in water-based wood coatings, UV-curable coatings, industrial anti-corrosion coatings, architectural coatings, etc., to endow coatings with matte texture and improve decorativeness and stain resistance.
2. Inks Industry: Suitable for offset inks, flexographic inks, screen printing inks, improving the printability and drying speed of inks, and making printed patterns clear with long-lasting matte effects.
3. Plastics and Rubber: Added to PP, PE, PVC, silica gel and other materials to prepare matte plastic parts and rubber products, such as home appliance shells, automotive interiors, seals, etc.
4. Leather and Textiles: Used in leather finishing agents and textile coating finishing agents to achieve matte treatment of leather and fabrics, enhancing touch and visual grade.

Usage Recommendations

1. Addition Level: According to the system type and target gloss, the recommended addition amount is 1%-10% (mass fraction), which can be adjusted through experiments.
2. Dispersion Method: It can be directly added to the system and stirred at high speed (1000-2000 r/min) for 10-20 minutes; or first prepared into a masterbatch and then mixed with the main material for better dispersion effect.
3. Storage Conditions: Seal and store in a cool, dry and ventilated place, avoid moisture and heavy pressure. The shelf life is 12 months.
