OEM Reactive Siloxane Glass Coating – Extreme Hardness Formula for Glass
―――
1. Product Concept
This product is a reactive siloxane-based cured water-repellent coating designed for automotive glass surfaces.
Its reactive components chemically bond with hydroxyl groups on the glass surface, forming a dense and durable hydrophobic layer.
After curing, the surface exhibits strong water-sliding properties—water beads and quickly runs off under airflow while driving.
In addition to excellent water repellency, the coating provides superior anti-stain, abrasion, and weather resistance, maintaining clear visibility for up to 12 months.

2. Composition & Key Features
・ Type: Reactive siloxane-based glass water-repellent coating
・ Form: Liquid (cured type)
・ Recommended Usage: Approx. 10 ml per vehicle (for front and side windows)
・ Applicable Surfaces: Automotive glass (tempered or laminated)
・ Durability: Approx. 12 months
Key Features
・ Chemically bonds with the glass surface through a siloxane reaction, forming a durable film.
・ High water contact angle and low surface friction ensure excellent visibility in wet conditions.
・ Excellent abrasion resistance, maintaining performance under wiper operation.
・ Reduces adhesion of oil film, water spots, and dirt for easier cleaning.
・ Fluorine-free, environmentally friendly formulation.

3. Performance & Characteristics
Water Repellency
The siloxane-cured film strongly adheres to the glass surface, creating a dense hydrophobic layer.
Water beads instantly and runs off even at low speeds, providing smooth water-sliding performance.
Durability
The chemically hardened inorganic coating resists abrasion, UV exposure, and temperature fluctuations,
retaining strong water-repellent properties for approximately 12 months under normal conditions.
Anti-Stain Properties
Prevents the adhesion of oil, dust, and water stains, maintaining long-lasting transparency and gloss.

5. Application Method
1. Thoroughly clean and degrease the glass surface before application.
2. Apply evenly to the dry glass surface using a sponge or applicator.
3. Rub evenly in both vertical and horizontal directions until application traces become less visible.
4. Without waiting for drying, immediately wipe the surface with a clean, dry cloth to finish.
5. Avoid exposure to water or wiper operation for 24 hours after application.
(If oil film or old water-repellent coatings remain, be sure to perform pretreatment using a glass cleaner or degreaser before application.)

6. Precautions During Application
・ Avoid application under direct sunlight or on hot glass surfaces.
・ Do not apply in rainy or high-humidity environments.
・ Keep the surface dry and free from friction for 24 hours after application.
・ Operate wipers only after the coating has fully cured.
