The matte coating brings out a unique texture due to the rough and uneven surface. On the other hand, these uneven surfaces are easily filled with inorganic minerals contained in tap water or muddy water, making it easy for water stains to adhere to the surface. In addition, conventional inorganic body glass coatings often cause severe water spots because the same inorganic minerals tend to adhere. Matte Texture KeePer is a patented coating technology that covers the surface with a glass film and an organic resin film, which fundamentally prevents water stains from setting in, making it suitable for matte paints.
