Advantages of KMEW Facade Panels

KMEW’s facade panels feature ceramic and photocatalytic coatings that suppress discolouration and fading, maintaining their original appearance for decades. Even after 30 years, they retain the beauty of a newly built home.

How KMEW Facade Panels Maintain Their Beauty

Structure of KMEW facade panel

Photocatalytic coating（ Dirt decomposition / Super hydrophilia / Antiviral, antibacterial properties / Air purification ） / Ceramic coating ( Prevents colour fading from UV rays ) / Colour layer / Substrate
KMEW’s facade panels turn sunlight and rainwater—typical causes of material deterioration—into allies, breaking down and washing away stains to preserve their beauty.

Ceramic Coating Technologies

Prevent colour fading from UV rays

KMEW’s exclusive ceramic coating technology—the only one of its kind applied to facade panels—offers outstanding resistance to fading and discolouration caused by UV rays. Unlike organic coatings, which are prone to deterioration over time, this advanced inorganic finish helps preserve the panel’s appearance and colour for years to come.

  • Organic coating
    Photocatalytic reaction occurs on the surface / Organic enamel layer is destroyed. Paint film peels and cracks
  • Ceramic coating
    (Inorganic clear coating)
    Photocatalytic reaction is controlled at the surface / Inorganic UV absorbers are strong and resistant to degradation / Inorganic resins are little or no degradation over time

Photocatalytic Coating Technology

Decomposition of surface contaminants

Using UV rays, the photocatalytic coating decomposes organic dirt and surface contaminants, enabling rainwater to rinse them away.

    Surface contamination
    1. Contaminated surface
  • 2
    Decomposition initiated
    by sunlight (UV)
    2. Sunlight decomposes dirt on exterior walls, weakening its adhesion for easier removal

Hydrophilicity

Because the photocatalytic coating is highly hydrophilic, rainwater spreads evenly across the surface, lifting and washing away the decomposed stains.

Air purification

The photocatalytic coating decomposes harmful substances in the air, such as from exhaust gases, and renders them harmless.
