摘要

methods for spraying a coating composition, with or without a flame retardant, onto a wood product and wood products produced by the method are disclosed. the method comprises a two-component system comprising (i) one or more aliphatic isocyanates and (ii) one or more aliphatic amines, and, optionally, one or more flame retardants, which are stored separately and combined in a spray gun to form a mixture which is then sprayed onto the wood product to form an outer coating on one or more surfaces of the wood product. wood coated with the compositions disclosed here has greater structural stability and is resistant to separation and / or division when compared to untreated wood.
