Surface‑Modified Silica Flour 15μm is silane‑surface‑treated crystalline silica flour serving as direct replacement for MIN‑U‑SIL 15. Silane coupling improves interfacial compatibility between mineral particles and resin matrix. When incorporated into coating and polymer formulations, this filler enhances scratch and abrasion resistance, increases mechanical strength, and develops stable matte texture on finished surfaces of molded parts and coated films.

Product Detail

Product Overview Surface‑Modified Silica Flour 15μm (CAS 14808‑60‑7, MIN‑U‑SIL 15 Equivalent) is finely ground crystalline silica flour processed via silane surface modification. Median particle size is controlled at 15 μm. The silane treatment optimizes wetting and bonding between silica particles and organic polymer matrix. After uniform dispersion within coating slurry or molten polymer, rigid silica particles reinforce the composite system. It improves scratch‑proof and abrasion‑resistant performance of cured articles and creates even matte surface texture. This mineral filler is suitable for heavy‑duty industrial coatings, modified engineering plastics and hard thermoset composite components.

Key Features ‑ Silane surface modification strengthens interfacial adhesion between silica and polymer resin ‑ Controlled 15 μm particle size generates uniform matte texture on finished surfaces ‑ Enhances scratch resistance and abrasion performance of coatings and molded polymer parts ‑ Exhibits excellent thermal stability under high‑temperature extrusion and molding conditions ‑ Direct functional equivalent grade for MIN‑U‑SIL 15 surface‑modified silica flour

Typical Technical Properties ‑ Chemical Type: Silane‑modified crystalline silica flour ‑ Appearance: Off‑white free‑flowing fine powder ‑ Median Particle Size: 15 μm ‑ Bulk Density: Refer to TDS ‑ Silane Treatment Level: Refer to TDS

Applications ‑ Industrial heavy‑duty coating: Matte‑textured reinforcing mineral filler for anti‑corrosion topcoats ‑ Engineering plastic modification: Abrasion‑resistant filler for thermoplastic compound granules ‑ Thermoset composite: Functional mineral filler for rigid moulded thermoset components ‑ Polymer compounding plant: Raw modified silica flour for custom matte‑finish polymer formulations

Processing Recommendation Feed surface‑modified silica flour during high‑speed mixing or kneading process. Adjust filler loading according to target abrasion‑resistance and matte‑texture requirements. Guarantee sufficient homogenization. Conduct lab compounding trials prior to large‑scale production.

Storage & Handling Store in cool, dry warehouse, keep away from moisture and external contamination. Reseal packaging immediately after opening. Wear dust‑proof mask and protective gloves when handling fine mineral powder.
