An object of the present invention is to provide an aluminum phospite having spherical shape. An aluminum phosphite of the present invention has the following formula.
Al.sub.x(OH).sub.y(HPO.sub.3).sub.3.Math.zH.sub.2O wherein: x represents 2.01 or more and 2.50 or less, y represents 0.03 or more and 1.50 or less, and z represents an integer of 0 to 4, respectively.

The present disclosure provides a fire retardant composition that includes a non-intumescent composition and an intumescent composition, fire retardant coatings including the same, and methods of preparation and use thereof.

A vent with louvres or punched holes for allowing airflow between an exterior of a vehicle and an engine bay of the vehicle, wherein the vent has an exterior side and an interior side and is formed from a panel, in which the louvres or the punched holes are located, wherein the interior side of the vent is provided with an intumescent coating. The intumescent coating will inhibit the spread of flame from the engine bay to the exterior of the vehicle thus containing the fire for a much longer period.

An intumescent nanostructured material for thermal protection comprising a member including a plurality of nanostructured materials, and an intumescent material associated with the member and configured to react in the presence of a heat source to form a foam for thermally insulating the member from the heat source. The member may be a non-woven sheet, a woven sheet, a yarn, or a network, and may be configured to conduct thermal energy away from a heat source. A solution comprising a plurality of nanostructured materials, an intumescent material, and a solvent, wherein the solution has a viscosity suitable for coating or spraying onto a surface of a substrate. The solution may have a viscosity of about 3000 centipoise to about 6000 centipoise, and possibly less than about 1000 centipoise. The solution, when dried on the substrate, may form a thermally-protective coating on the substrate.

A composition that forms an insulating layer contains an epoxy-thiol-based binder. Because the expansion rate of the composition is relatively high, coatings having the layer thickness required for the relevant fire resistance duration can be applied in a simple and rapid manner, and it is possible to reduce the layer thickness to a minimum while still achieving a good insulating effect. The composition is particularly suitable for fire-protection, in particular as a coating for metal and non-metal substrates, e.g., steel components such as supports, beams, and truss members, to increase the fire resistance duration thereof.

An intumescent coating system contains: a polyol component; an isocyanate component; a latent crosslinker having two or more —NACH.sub.2OR groups, where A is selected from a group consisting of H and —CH.sub.2OR, and in each case R is independently selected from a group consisting of hydrocarbons having from one to four carbons, the latent crosslinker being present at a concentration of 30 weight-percent or more based on polyol weight; a boron component one weight-percent or more and 10 weight-percent or less based on total weight of the formulation; and expandable graphite at a concentration of 10 weight-percent or more and 50 weight-percent or less based on the total intumescent system weight; where the polyol and isocyanate are selected so that the reaction product at room temperature of the intumescent coating system components produces a coating having a tensile elongation of 40-percent or more as determined according to ISO 37.

Aqueous intumescent coating compositions which include a non-ionic surfactant having a hydrophilic-lipophilic balance (HLB) of 9 to 20, and substrates coated with the coating composition are disclosed. Inclusion of the non-ionic surfactant in the coating compositions is found to reduce char cracking and improve the mechanical strength, cell size, and cell density for intumescent chars formed when coatings deposited from the coating compositions are exposed to open flame and/or elevated temperatures, as compared to the same coatings lacking the non-ionic surfactants.
