Professional Specification & Application of Automotive Glass Rare Earth Polishing Powder
Product Definition
This professional automotive glass polishing powder is formulated with high-purity cerium oxide (CeO₂) and lanthanum oxide (La₂O₃). Adopting advanced Chemical Mechanical Polishing (CMP) technology, it efficiently restores transparency to scratched, foggy and stained automotive glass without damaging the glass substrate. Integrating chemical activation and physical micro-abrasion, it outperforms traditional abrasives and serves as a premium solution for professional auto maintenance and detailing industries.
Product Application
Rare earth polishing materials are widely recognized as optimal abrasives for glass finishing, featuring high polishing efficiency, superior surface finishing and low environmental pollution, earning the title "King of Polishing Powders". Composite abrasive grains modified by polymer and inorganic coating further enhance polishing stability. Specially optimized cerium-based formulas effectively improve the flatness, smoothness and surface cleanliness of automotive glass, meeting industrial precision finishing standards.
Core Application Scope
Applicable to all automotive glass types, including laminated windshields, tempered side windows, rear glass and rearview mirrors. It professionally repairs common glass defects: light-to-medium wiper scratches and particle abrasion marks (≤0.3mm depth), stubborn oil films, water spots, UV aging fogging, surface whitening and residual adhesive stains.
Safety Note: It is not applicable to deep cracks, structural damage and severe scratches in the driver's main viewing area, which require professional inspection or glass replacement.
Composition, Particle Parameters & Working Principle
The product contains ≥63.00% cerium oxide and ≥24.00% lanthanum oxide. With a D50 particle size of 1.0–1.5μm, it is customized for fine polishing and surface brightening.
With stable chemical properties and 6–7 Mohs hardness, the powder achieves balanced grinding performance without over-cutting the glass. It produces effective chemical reactions with silicate glass to form stable polishing slurry and realize efficient scratch removal. The neutral pH value (approx. 7) guarantees stable polishing performance under variable temperature and water quality conditions.
ODM Customization Service
We support customized production with a weekly output of 10,000 KG. Standard formula delivery takes 7–15 days, and customized formulas take 15–30 days. Supported by a professional R&D team focusing on rare-earth materials and automotive glass technology, we provide targeted formula optimization. Flexible logistics solutions including sea, road and railway transportation are available via Shanghai, Shenzhen and Guangzhou ports to ensure stable global supply.
Professional & DIY Operation Guidelines
Professional Polishing Process
Clean and dry the glass thoroughly; mix polishing powder and water at 1:5 to form uniform slurry. Polish the glass with wool or sponge pads at 1500–2000 RPM with circular motions, replenish slurry timely during operation. After polishing, clean residual slurry with fine pads and microfiber cloths, and apply hydrophobic coating for long-term protection.
DIY Operation Guide
Suitable only for shallow scratches (＜0.1mm) in non-key viewing areas. Clean and dry the glass first, mix a small amount of powder with water, wipe the defective area gently in circular motions until defects disappear, then rinse and dry the surface.
Quality Assurance
The unopened product has a 120-month shelf life under dry storage conditions. Professional technical teams provide one-stop services including application guidance, fault troubleshooting and formula upgrading.
