How Long Does It Take for Underbody Coating to Dry?

[DelJessica]

Underbody coating takes about a week to dry in winter and three days in summer. Below are the functional features of underbody coating: Stone Impact Protection: While driving, small stones can be kicked up, and the force of their impact on the underbody is proportional to your speed. For example, a 10-gram stone traveling at 80 km/h can generate an impact force 30,000 times its own weight—equivalent to hitting an egg with a stone! This is enough to break through paint layers thinner than 30 microns. Once the paint is damaged, rust starts at the defect and slowly spreads from within the metal sheet. After underbody treatment, even a 300 kg impact from gravel cannot penetrate the coating. Heat Insulation and Fuel Efficiency: During summer, the cold air from the car's air conditioning sinks downward, while the hot air from the ground rises. Most of this heat exchange occurs at the vehicle's floor. The effectiveness of underbody protection directly determines how efficiently the vehicle's cooling energy is utilized. After underbody treatment, the honeycomb-structured sound-absorbing factors in the coating film completely isolate the hot and cold air.
