Underbody Coating

Undercoating

Undercoating is the sprayed application of a wax or rubber-based composite onto the entire underside of the vehicle. It's designed to create a rust-proof layer between the underside of the vehicle and the water, ice, and salt of the road.

Undercoating provides a more comprehensive protective layer for our vehicle. This includes the floorboards, wheel wells, and frame. Even if our car's underside isn't actually visible, it is still exposed to potential damage when we go out driving. Things like dirt, debris, mud, and salt are kicked up from the road and get into the nooks and crannies of our vehicle's undercarriage. So in addition to protecting against rust and corrosion, it also provides additional protection from the nastiness the road coughs up.

Device are used to check the thickness of material applied on to surface to check the quality of undercoating using elecometer (coating thickness gague).

A coating thickness gauge (also referred to as a paint meter) is used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality and cost. Dry film thickness measurements can be used to evaluate a coating’s expected life, the product’s appearance and performance, and ensure compliance with a host of International Standards.

How to measure Dry Film Thickness?

Dry film thickness (DFT) can be measured using two methods: destructive thickness measurement, where the coating is cut to the substrate using a cutter; and non-destructive coating thickness measurement, using techniques which do not damage the coating or the substrate such as magnetic, magnetic induction and eddy current thickness measurement methods.
