Methods for spraying a coating composition, with or without a fire retardant, onto a wood product, and wood products produced by the methods are disclosed. The method comprises a two-component system comprising (i) one or more aliphatic isocyanate compounds; and (ii) one or more aliphatic amine compounds, and, optionally, one or more fire 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 external coating on one or more surfaces of the wood product. Wood coated with the compositions disclosed herein have increased dimensional stability and are resistant to checking and/or splitting compared to untreated wood.
本发明公开了将含或不含阻燃剂的涂料组合物喷涂到木制品上的方法,以及用该方法生产的木制品。该方法包括一个双组分系统,该系统由 (i) 一种或多种脂肪族异氰酸酯化合物;和 (ii) 一种或多种脂肪族胺化合物,以及可选的一种或多种阻燃剂组成,它们分别储存并在喷枪中混合形成混合物,然后喷涂到木制品上,在木制品的一个或多个表面形成外涂层。与未经处理的木材相比,涂有本文所揭示的组合物的木材具有更高的尺寸稳定性和抗开裂和/或劈裂的能力。
