Lightweight underbody coatings and sealants with Expancel

The volume contribution of the microspheres is key in getting the best out of an expandable sealant. This can be used to fill cavities, and for sound and vibration dampening. The microspheres are also able to pass the spray nozzle unbroken while maintaining their volume.

With Expancel, even in waterborne systems, you will develop underbody coatings and sealants with a lower density, better protection and improved insulation. Even at low additions. All of which are invaluable benefits in a very competitive industry.
