Flexible, insulative fire protective coatings and coated materials

摘要

Aqueous coating compositions containing a film-forming polymer, at least one flame retardant or smoke suppressant, glass or ceramic microballoons, and expandable flake graphite may be applied to building components pre- or post-installation, and provide a flexible and adherent coating. When exposed to heat, the coating expands to form an insulative yet cohesive layer which protects the component from fire-induced damage.
