Latest Patents

John F. Hadley's latest patents focus on enhancing fire safety in building construction. One of his notable inventions is the **Fire Resistant Foam Insulated Building Panels**. This patent describes a building panel made up of two skins that encompass a cellular plastic core, with a fire-resistant coating on at least one inner surface. This unique coating is composed of a film-forming organic polymer mixed with solid, reactive ingredients that react to heat by releasing nonflammable gases. This reaction causes the film to expand, forming an insulating barrier significantly thicker than the original coating, providing enhanced protection against fire hazards.

Another significant invention is the **Sodium Silicate Extended Polyurethane Foam**. This technology results in polyurethane foam products featuring low combustibility, low flame spread ratings, and minimal smoke generation in fire conditions. By integrating aqueous sodium silicate into the foam formulation, which also includes a viscous, hydroxyl-terminated polyester and a polyisocyanate prepolymer, Hadley's invention achieves a foam density of 1.5 to 4.5 pounds per cubic foot. The innovative properties of this foam make it a valuable thermal insulating material, especially suitable for use in building panels.
