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. Q-CEL® hollow spheres can reduce the compound density of PVC Plastisols and seam sealers. As tiny particles of encapsulated air, Q-CEL® hollow spheres efficiently displace some polymer in plastics formulations, since a very small weight produces a large volume displacement.
