November 12, 2025 – LSAK Feldspar （Henan Ankai New Materials Co., Ltd.） today announced that its high-purity soda feldspar (albite) has been successfully integrated into premium clear coating formulations, enabling coatings manufacturers to achieve breakthrough performance: 20% higher gloss, 15% enhanced durability, and 15–20% lower production energy consumption. The product is rapidly becoming the “transparent gloss engine” for high-end applications in furniture finishes, automotive refinishes, artistic coatings, and industrial protective systems.
Soda Feldspar: The “All-in-One Performance Booster” for Clear Coatings
As a natural mineral flux, Ankai’s soda feldspar—characterized by ultra-low iron content (Fe₂O₃ ≤ 0.15%) and a highly transparent sodium-aluminum-silicate matrix—delivers four core advantages in clear coating formulations:
Mirror-Level Gloss: With SiO₂ at 66% ±2, it ensures crystal-clear transparency rivaling high-end synthetic resins.
Exceptional Film Durability: Al₂O₃ at 19.5% ±0.5 and Na₂O at 10.5% ±0.5 significantly enhance hardness and scratch resistance.
Flawless Flow & Leveling: Precisely modulates solvent evaporation to eliminate pinholes, orange peel, and surface defects.
Green & Low-Carbon Production: Its low melting point reduces curing temperatures, supporting the industry’s shift toward zero-carbon coatings by 2025.
“Soda feldspar isn’t just a filler—it’s a performance catalyst in clear coating formulations,” said the Technical Director of Ankai New Materials. “With our ultrafine powder design (D50 = 10μm), we’ve helped multiple clients achieve coating yield rates exceeding 98%.”
Waterborne & UV-Curable Systems: Non-yellowing and highly transparent—ideal for replacing conventional chemical additives.
Low-VOC & Bio-Based Clear Coats: Naturally sourced mineral enables truly “green” formulation transitions.
Functional Topcoats: Provides a robust film foundation for advanced features like antimicrobial or self-healing properties.
Ankai soda feldspar is already supplied to luxury Italian furniture brands and integrated into China’s new-energy vehicle refinish paint systems, serving over 50 premium coatings companies worldwide.
