Sealants and Underbody Coatings

Lightweight PVC Plastisols have become the material of choice for automotive underbody coatings to protect the undercarriage from corrosion and chipping.  hollow spheres can reduce the compound density of PVC Plastisol spray and seam sealers at a fraction of the cost. hollow spheres replaces costly engineered resins and improves rheological characteristics of viscous compounds while reducing overall weight of vehicles.

 As tiny particles of encapsulated air, hollow spheres efficiently displace some polymer in plastics formulations, since a very small weight produces a large volume displacement.
