Matting powder (also known as matting agent, flatting powder, matte powder, or dull powder) features characteristics such as high pore volume, a molecular structure of polyhedral prisms, narrow particle size distribution, ideal specific surface area, and high oil absorption value. In practical applications, it fully demonstrates high adsorption, matting properties, multiple thixotropy, and anti-stickiness. It can be widely used for matting and thickening in coatings, anti-stickiness in resins, adsorption in printing media, and surface treatment of leather, among others. This product can significantly improve the physical and mechanical properties of resin in a wet state, offering good acceleration of dispersion and anti-settling effects. It can notably enhance the gloss of the coating film, achieving an excellent matting effect.

Technical Indicators:

Product Applications:
1、Coating:In coatingsAddVK-SP15 has excellent matting properties, and when added 0.5-10After adding % of nano-silica (which needs to be fully dispersed), its suspension stability, thixotropy, and the coating and substrate...The bonding strength and other properties were significantly improved, the drying time was shortened, the duration of artificially accelerated UV aging tests was multiplied, the scrub resistance was increased from thousands to tens of thousands of times, and the stain resistance of the coating was also notably enhanced.

2、Plastic: NanometerTwoSilicon oxideVK-SP15Fully dispersed in plastic raw materials such as polypropylene (PP) and polyvinyl chloride (PVC), it can significantly enhance the strength, toughness, wear resistance, and anti-aging properties of plastic products.The excellent light transmittance and small particle size of nano-silica can make plastics denser. Particularly for translucent plastic films, the addition of nano-silica not only enhances the film's transparency, strength, and toughness, but more importantly, significantly improves its waterproof performance. Experiments have shown that the water permeability of conventional PVC (polyvinyl chloride) film is 1.5 times higher than that of PVC film with added nano-silica.

3. Adhesives: Nano-silica used in adhesives can significantly enhance bonding strength. The tensile strength and elongation rate increase by 21% and 23%, respectively, compared to adhesives without nano-silica fillers.

4. Inkjet Printing and Photo Paper: The coating uses nano-scale silicon dioxide material to form extremely fine inorganic-organic composite particles. Once ink is printed, it is immediately absorbed by honeycomb-like micropores. The coating has strong ink absorption, allowing it to present excellent layering even in deep-toned areas. It dries quickly, so it can be touched directly as soon as it comes out of the printer. The coating material is very fine and also has good waterproof performance, maintaining its original state even after being soaked in water for several hours. Its advantages are summarized as "three highs and one fast": high gloss, high
