OEM Reactive Siloxane Glass Coating – Premium Hardness Formula for Unpainted Plastic Molding
1. Product Concept
This product is a reactive siloxane-based high-hardness glass coating formulated specifically for unpainted plastic moldings.
It restores the original color and gloss of faded plastic trim while providing hydrophobic, anti-soiling, and weather-resistant protection lasting approximately 6–12 months.
It shields vulnerable plastic components from UV exposure, acid rain, and contamination to maintain a refined exterior appearance.
2. Composition & Key Features
・ Type: Reactive siloxane-based high-hardness glass coating (for unpainted plastic moldings)
・ Form: Liquid
・ Recommended Usage: Approx. 8 ml per vehicle
・ Applicable Surfaces: Unpainted plastic moldings, bumpers, mirror covers, door handles, and textured resin components
・ Finish: Restored dark tone and gloss with hydrophobic and weather-resistant performance
Key Features
・ Revives faded and chalked unpainted plastics
・ Forms a durable hard glass coating with long-lasting protection
・ Protects against UV rays, acid rain, and environmental degradation
・ Easy application with thin coating and immediate wipe-off
3. Performance & Characteristics
Reactive siloxane components bond tightly to unpainted plastic surfaces and form a hard glass-like coating.
This coating suppresses fading and chalking while adding hydrophobic and anti-soiling performance, making routine maintenance easier.
Unlike petroleum-based dressings that oxidize and degrade quickly, this coating maintains gloss, water repellency, and durability over a long period.
4. Recommended Application Areas
・ Unpainted bumpers
・ Unpainted side or fender moldings
・ Unpainted mirror covers and door handles
・ Unpainted plastic trim on motorcycles and scooters
5. Application Method
- 1. Rinse off dust, sand, and mud thoroughly, then wash with an appropriate cleaner.
- 2. Dry completely to ensure no moisture remains on the surface.
- 3. Apply a small amount to a coating sponge and spread an extremely thin, even layer.
- 4. Before curing begins, wipe off completely with a clean microfiber cloth and check for residue.
6. Precautions During Application
・ For unpainted textured plastic only. Do not use on transparent parts or soft materials.
・ Thick application may cause cracking or streaking; always apply thinly.
・ Do not apply over remaining stains or water spots as they may become permanently sealed.
・ Avoid high temperatures, direct sunlight, and exposure to water for 6 hours after application.
