OEM Reactive Silica Glass Coating – Superior Hardness Formula for Headlight
1. Product Concept
This product is a hand-applied, reactive silica-based glass coating specifically developed for polycarbonate headlamp covers.
It forms a dense silica framework upon curing, providing long-lasting protection against haze and yellowing.
Maintains optical clarity and transparency while offering superior hydrophobic and anti-stain performance.
2. Composition & Key Features
・ Type: Hand-applied, reactive-curing, wipe-off type
・ Applicable Substrate: Polycarbonate headlamp covers
・ Recommended Usage: Approx. 4 ml per vehicle (both sides)
・ Form: Liquid (curing type)
・ Finish: Clear, high-gloss, high-hardness (9H equivalent)
Key Features
・ Forms a dense silica framework through reactive curing
・ Prevents yellowing and haze for extended clarity
・ Provides hydrophobic and anti-stain performance
・ Maintains light transmission and surface smoothness
3. Performance & Characteristics
Protection & Weathering: Shields polycarbonate surfaces from UV, acid rain, and road contaminants.
Optical Clarity: Smooth silica coating minimizes light diffusion and maintains visibility.
Hydrophobic & Anti-Stain: Repels water and dirt, reducing maintenance needs.
High Hardness: Up to 9H pencil hardness protects from micro-scratches.
4. Recommended Application Areas
・ Polycarbonate headlamp covers
・ Transparent polycarbonate fog lamp covers
5. Application Method
- 1. Rinse off dust and mud, then wash with a neutral shampoo.
- 2. Dry thoroughly to remove all moisture.
- 3. Apply a small amount to an applicator and spread very thinly and evenly.
- 4. Within 2–3 minutes (before curing), wipe off completely with a clean microfiber towel.
- 5. Inspect for streaks or residues.
[Preparation] If haze or yellowing exists, polish with a plastic compound, then degrease and dry before coating.
6. Precautions During Application
・ Avoid direct sunlight or hot surfaces.
・ Do not apply thickly to prevent haze or streaks.
・ Ensure complete wipe-off within 2–3 minutes before curing begins.
