Equatorial climates combine high heat, persistent humidity above 85%, and daily UV index ratings above 11. These severe conditions accelerate hydrophobic topcoat degradation and yellowing in lower-grade TPU films.
Morthink technical specialists monitored a white Porsche Taycan wrapped in MoShiEx LHOTE Series PPF over 36 continuous months of outdoor street parking in Singapore, taking bi-monthly gloss, color shift (Delta E), and contact angle measurements.
After 3 years, laboratory spectroscopy confirmed Delta E color shift remained below 0.8 (imperceptible to human eyes), hydrophobic water contact angle stayed above 102°, and ambient heat self-healing performed flawlessly.
