Automotive coatings and body fillers
Reduce weight and dampen sound and vibration
Lightweight underbody coatings and sealants with Expancel® Microspheres
Our Expancel® microspheres are used as a blowing agent in plastisols, for underbody coatings and sealants. They possess low density plus high elasticity and a uniform cell structure. These characters enable you to reduce weight and improve the stone chip resistance of the underbody coating. By being able to produce automotive parts that are lighter in weight, our microspheres assist in better fuel efficiency overall.
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® microspheres, you will develop underbody coatings and sealants with a lower density, better protection, and improved insulation at low additions, even in waterborne systems. All of which are invaluable benefits in a very competitive industry.
Expancel® Microspheres for lightweight body fillers with improved sandability
As 1% of our Expancel® microspheres reduces densities by up to 46%, our expandable microspheres let you up the volume without adding weight of your body filler.
The small sizes of the uniform, closed cell spheres let you achieve amazing surface appearances and no pinholes on your body filler. Plus, they provide excellent sanding properties – reducing the sanding time of the body filler. Exchanging glass bubbles for Expancel® microspheres inadvertently minimizes wear on sanding tools.
Our microspheres are super easy to apply as their adhesion to resin is excellent. They possess a closed cell structure, which means that water will find it hard to penetrate a surface coated with a body filler containing Expancel® microspheres. They'll also reduce cracking and shrinkage of the dried body filler and have a low impact on the curing parameters.
With Expancel® microspheres, you can rely on a lightweight, highly protective, and cost-reducing ingredient that adds enormous value to automotive production processes.
