Abstract
A coating material for a lightning-prone object includes a base color substance and an additive admixed with the base color substance. The additive comprises rigid hollow beads filled with an inert gas. At least a portion of the hollow beads have an electrically conductive coating.
Claims15
An aircraft comprising at least one outer surface coated with a coating material for a lightning-prone object, the coating material comprising:
- a base color substance, and
- an additive admixed with the base color substance,
- wherein the additive comprises rigid hollow beads which contain a volume of an inert gas that exceeds an internal volume of the rigid hollow beads, such that particles of the inert gas apply a pressure above the ambient pressure to the rigid hollow beads, and
- wherein at least a portion of the hollow beads have an electrically conductive coating on an exterior surface of the hollow beads.

A method for coating a lightning-prone object, comprising:
- applying a coating material which includes a base color substance admixed with an additive to the lightning-prone object, wherein the applying is accomplished by spraying,
- wherein the additive comprises rigid hollow beads filled with an inert gas which is stored in the rigid hollow beads with an overpressure, and
- wherein at least a portion of the hollow beads have an electrically conductive coating on an exterior surface of the hollow beads.
An aircraft comprising at least one outer surface coated with a dual coating for a lightning-prone object, the dual coating comprising:
- a coating material including:
- a base color substance, and
- an additive admixed with the base color substance, and
- a clearcoat which covers the coating material,
- wherein the additive comprises rigid hollow beads which contain a volume of an inert gas that exceeds an internal volume of the rigid hollow beads, such that particles of the inert gas apply a pressure above the ambient pressure to the rigid hollow beads, and
- wherein at least a portion of the hollow beads have an electrically conductive coating on an exterior surface of the hollow beads.
