GRASi Integrated Protection Solutions for Automotive Hydrophobicity and Easy Cleanability

Values: Timeless Beauty, Lasting Protection

Protection Scope: Vehicle Paintwork, Car Windows, Interior Surfaces

In the rhythm of urban life, automobiles have transcended mere transportation to become an extension of our lifestyle and personal taste. Every smooth contour, every delicate detail, speaks to the designer’s craftsmanship and the owner’s aesthetic. Yet, in this unpredictable world, a car’s beauty faces relentless challenges—rain and wind, scorching sun, dust intrusion, and the passage of time.

Vehicle Paintwork

This outer layer that endow automobiles with soul and personality，undergoes silent battles daily. Morning dew evaporates in the sun, leaving imperceptible watermarks; afternoon showers mix with urban dust, staining the paint with mottled marks (surface contaminant adhesion reaches 150g/㎡); evening acid rain quietly erodes the paint’s luster (annual gloss loss ΔGU15), dimming once-vibrant colors. In rainy southern China, paintwork stays in high humidity (annual average humidity 80%), prone to water stains and oxidation (oxidation rate increased by 300%); in northern regions, frequent temperature fluctuations (45 annual freeze-thaw cycles) and sandstorms (PM10 concentration 150μg/m³) accelerate aging (micro-scratch density: 25 lines/cm²) and micro-scratch formation. Industrial dust, splashed mud, sticky tree sap, and corrosive bird droppings in urban environments gradually erode the paint’s beauty. We often accept our cars losing luster as an inevitable "gift of time."

Car Windows

These transparent portals connecting the interior and exterior are always the first troubled by the environment. During rainy drives, water films on glass severely reduce visibility (light transmittance loss reaches 35%), increasing driving risks; after rain, water stains and dirt leave unsightly marks (cleaning frequency: 3 times/week), compromising both aesthetics and safety. We watch the blurred view, seemingly only able to maintain it through frequent cleaning.

Interior Surfaces

This private space we interact with daily faces the test of daily use. Accidental spills of drinks on seats quietly alter the interior’s texture and appearance (annual color difference ΔE5). These seemingly minor changes directly affect our driving experience and mood.

The GRASi Transformation

These seemingly inevitable nuisances are not insurmountable. In the ongoing exploration of automotive surface protection, GRASi technology brings delightful changes. It’s like cloaking the vehicle in an invisible armor, restoring lasting luster to the paint, keeping windows clear, and rejuvenating interior surfaces.

When rain falls, it’s no longer a nuisance but a natural cleaner, forming water droplets that roll off to carry away dust and stains (self-cleaning efficiency: 92%).

• When sunlight shines, it no longer accelerates aging but becomes a stage to showcase the paint’s brilliance (60° gloss maintained at 98).
• When touched, it no longer leaves hard-to-remove marks (surface energy reduced to 18mN/m) but retains original texture and beauty.
• This transformation is not temporary but enduring—like time passing, yet the vehicle’s appearance remains eternally elegant.

Case Study: High-End Vehicle Maintenance at an International Auto Exhibition Center

We witnessed the outstanding performance of GRASi nano-protection technology in a maintenance project for luxury display vehicles. These valuable cars needed long-term exhibition under intense lighting (illuminance 80,000lux, daily UV radiation 12kWh/㎡) and close viewing/touching by thousands of visitors daily (contact frequency 300 times/㎡), demanding extreme surface protection. After treating the paint (pencil hardness increased to 9H), glass (light transmittance retention 99.8%), and interiors (stain resistance level 5) with GRASi nano-protectants:

• Fingerprint and oil adhesion reduced by 90%
• Lighting-induced damage minimized (gloss retention ΔGU<2)
• Perfect display condition maintained throughout the exhibition

Post-exhibition evaluation showed treated surfaces retained excellent gloss (60° gloss: 98) and hydrophobicity (water contact angle 105°), with daily maintenance workload reduced by 70% (cleaning frequency: 0.3 times/week), while perfectly showcasing these top models’ design aesthetics. This success proves advanced GRASi protection not only offers practical daily care but also matches the premium status of luxury vehicles with distinguished protection.

This is more than surface protection; it’s a respect for the owner’s taste. Every meticulously cared-for car tells the owner’s attitude toward life and pursuit of quality. In automotive surface protection, we see not just technological progress but a philosophy of living—making every drive a pleasure and every appearance a scenic highlight.
