Surface‑Modified Silica Flour 15μm is silane surface‑treated crystalline silica flour as direct replacement for MIN‑U‑SIL 15. Silane coupling improves compatibility between mineral particles and polymer resins. When incorporated into coatings and polymer compounds, this filler enhances surface abrasion resistance, boosts mechanical strength, and delivers stable matte texture on finished molded or coated surfaces.

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 with silane surface modification. The median particle size is controlled at 15 μm. Silane treatment optimizes wetting and interfacial bonding with organic resin matrix. After uniform dispersion inside coating slurry or polymer melt, the rigid mineral particles improve scratch and abrasion‑resistant performance of cured articles. Meanwhile, the particle contributes to uniform matte surface texture without heavy matting agent dosage. This silica flour is applicable for industrial coatings, thermoset composites and modified engineering plastic formulations.

Key Features ‑ Silane surface modification enhances interfacial adhesion between silica and polymer resin ‑ Controlled 15 μm particle size creates consistent matte texture on finished surfaces ‑ Improves abrasion‑resistance and scratch‑resistance of coating film and molded polymer parts ‑ Good thermal stability during high‑temperature extrusion and moulding processing ‑ 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 coating: Matte‑texture reinforcing mineral filler for heavy‑duty anti‑corrosion topcoat ‑ Engineering plastic modification: Abrasion‑resistant filler for thermoplastic composite granules ‑ Thermoset composite: Functional mineral filler for hard moulded thermoset components ‑ Polymer compounding plant: Raw modified silica flour for custom matte‑finish polymer formulations

Processing Recommendation Add surface‑modified silica flour during high‑speed mixing or kneading stage. Adjust filler loading to balance abrasion‑resistance and matte texture requirement. Ensure sufficient homogenizing mixing. Complete lab compounding trials prior to mass production.

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