Taking sedans as an example, the thickness of the chassis coating is usually 400-1000 μ m, and the corresponding weight reaches 8.5-9.5kg. Adding microspheres to the primer can significantly reduce weight without affecting the wear resistance and corrosion resistance of the coating. Specifically, it can bring the following advantages:

Reduce weight by 50% while maintaining the same thickness

Environmentally friendly and non-toxic

The dense and uniform structure of microspheres allows for perfect fusion with highly resistant matrices;

Soundproofing and insulation properties
