White fused alumina grades commonly used for fluorocarbon weather-resistant topcoat Fluorocarbon coatings are cured at high baking temperature (230–260°C). Na₂O is the primary control index. Excessive sodium may cause blistering, loss of gloss, poor weather resistance and degraded salt spray performance. High iron content leads to yellowing and color shift, which is particularly critical for

White Fused Alumina WA (Abrasive Sand / Fused Alumina Powder) for Polishing Stainless Steel Sealing Parts Stainless steel sealing components, such as mechanical seal rings, valve seats and flange sealing faces, demand superior surface finish, flatness and consistent sealing performance. White fused alumina (WA, also called fused alumina or white emery) is widely adopted for

For light-colored epoxy coatings (white, off-white, light grey, food-grade & potable water epoxy), we recommend acid-washed low-iron high-whiteness white fused alumina, with Al₂O₃ ≥99% and Fe₂O₃ ≤0.05%. Silane-modified grades are preferred for waterborne epoxy, because they deliver better dispersion and less settlement. Coarse grades such as F240 and F320 are not recommended, as they will

White fused alumina have three major applications: sintering setter sand, grinding and polishing media, and epoxy encapsulation filler. ✅ Core Functions MLCC laminated sintering setter sand (the most mainstream application) Spread between setter plates and MLCC green chips: it separates and prevents sticking, provides point support, allows free shrinkage to avoid warpage, and facilitates gas

Core Advantages of White Fused Alumina for Matte Blasting of Precision Ceramics White fused alumina (high‑purity α‑Al₂O₃, Mohs hardness 9) features angular cutting edges, high purity, controllable self‑sharpening property and chemical inertness. It is ideal for uniform matte / velvet satin blasting of precision structural and functional ceramics such as alumina ceramic, zirconia ceramic, aluminum

White fused alumina micropowder is a functional wear-resistant skeleton filler rather than a reinforcing filler. The main reinforcing fillers remain silica and carbon black. α-Al₂O₃ Mohs hardness ：9.0, It features good acid & alkali resistance and excellent thermal conductivity. It is mainly used in light-colored rubber systems to solve common problems of ordinary fillers, such
