Application of High Strength/Low Specific Gravity Under Body Coat for Automobile 920739
The PVC(poly-vinyl chloride) underbody coating was specifically designed for the automotive underfloor area in order to prevent chipping damage as well as the onset of rust propagation from a scratched point.
This superior anti-chipping performance can also be achieved without increasing film thickness of the PVC by balancing film strength and adhesion strength.
Also, by incorporating plastic balloons in the PVC formulation, a dried film specific gravity of less than 1.0 is achieved, and consequently a 2 kg weight reduction becomes possible when compared to conventional materials used for underbody coating.
