Resistance to UV Rays
Specialized sheet prevents chalking degeneration, discoloration, and loss of gloss under strong sunlight.
Resistance to Humid Heat
Accelerated penetration protection prevents the degeneration of the painting film in hot and humid environments.
Resistance to Low Temperature
Maintains stable performance in alpine regions (-20°C to -40°C) where normal paint would become brittle or crack.
