A process is provided for treating wood products including lumber, plywood and other engineered wood products comprising the steps of applying an aqueous fire-retardant impregnate and applying a coating to the surface of the wood product. In one embodiment, said process confers fire-retardant properties to the wood products sufficient to pass the extended burn test of ASTM E-84. The present invention also provides fire retardant wood products.

A fire retardant, vapor impermeable coating composition is disclosed which is useful for protecting gypsum, wood, polyurethane, polystyrene, and other construction materials and surfaces, such as components for buildings. The composition does not require halogenated compounds and is considered environmentally friendly. The composition is provided in the form of a liquid-applicable aqueous latex comprising at least one latex polymer and an expandable graphite, optionally a hydrophobic thickener, and optionally other fire retardants such as metal hydroxides, wherein the polymer is selected such that the composition, when coated onto a substrate and allowed to dry, has a vapor permeability not exceeding one perm (5.7010.sup.8 g/Pa.Math.s.Math.m.sup.2 when tested according to ASTM E96B-10 at an average dry film thickness of 40 mils). The invention provides fire retardant air barrier layers for construction materials, such as polyurethane or polystyrene insulation beads or panels, as well as vapor impermeable laminates for construction applications.

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.
