Abstract
Particles that have an exterior surface coated with a thin polymer coating, such as a coating that includes a sulfur-containing polymer can be used as lightweight fillers in compositions, such as fuel resistant sealant and coating compositions. The compositions can be used to seal apertures on aerospace vehicles.
