    • Low formaldehyde emission wood based panels are described. These wood based panels have an outer surface layer comprised of a resin composition comprising a naturally occurring component or derivative thereof which is chemically bound to an aromatic hydroxyl compound-aldehyde resin (ncPF). The advantages of having an outer surface layer of the resin composition comprising ncPF, is that the outer surface layer can act as a surface sealer to reduce migration of components from the core of the wood based panel to the surface. The outer surface layer is pleasing to the consumer because it forms light colored faces on the wood based panel. It is also a superior surface for after treatment, such as for example, painting, when compared to amino or phenol resins. In addition, the outer surface layer comprising the inventive resin composition comprising ncPF can lend added fire-retardancy to the wood based panel.
    • 描述了低甲醛释放木质面板。 这些木质基板具有由表面层组成的树脂组合物,该树脂组合物包含与芳族羟基化合物 - 醛树脂(ncPF)化学结合的天然存在的组分或其衍生物。 具有包含ncPF的树脂组合物的外表面层的优点是,外表面层可以用作表面密封剂,以减少组分从木基板的芯到表面的迁移。 外表层对消费者来说是令人愉快的,因为它在木质面板上形成浅色面。 当与氨基或酚醛树脂相比时,它也是后处理的优异表面,例如涂漆。 此外,包含本发明的包含ncPF的树脂组合物的外表面层可以向木基面板增加阻燃性。

    • Resin compositions (A) and (B) are described: wherein resin composition (A) comprises a naturally occurring component or derivative thereof comprising protein, an aromatic hydroxyl compound-aldehyde resin and an amino resin, wherein the naturally occurring component or derivative thereof is chemically bound to the aromatic hydroxyl compound-aldehyde resin to form an ncPF resin and the naturally occurring component or derivative thereof is optionally chemically bound to the amino resin; wherein resin composition (B) comprises a condensation product of a naturally occurring component or derivative thereof, an aromatic hydroxyl compound-aldehyde resin and at least 20 wt% of urea based on the total mass of the resin composition, wherein at least 50wt% of the naturally occurring component or derivative thereof is chemically bound directly or indirectly to the aromatic hydroxyl compound-aldehyde resin (ncPF), and wherein the naturally occurring component or derivative thereof comprises protein. The resin compositions can be used as a binder for lignocellulosic or cellulosic materials which have an excellent combination of low formaldehyde emissions and high strength. Also described are low formaldehyde emissions wood products comprising unique binder combinations.
    • 描述了树脂组合物(A)和(B):其中树脂组合物(A)包含天然存在的组分或其包含蛋白质的衍生物,芳族羟基化合物 - 醛树脂和氨基树脂,其中天然存在的组分或其衍生物是 化学键合到芳族羟基化合物 - 醛树脂上以形成ncPF树脂,并且天然存在的组分或其衍生物任选地与氨基树脂化学键合; 其中树脂组合物(B)包含基于树脂组合物总质量的天然存在组分或其衍生物,芳族羟基化合物 - 醛树脂和至少20wt%脲的缩合产物,其中至少50wt%的 天然存在的组分或其衍生物直接或间接化学键合到芳族羟基化合物 - 醛树脂(ncPF)上,并且其中天然存在的组分或其衍生物包含蛋白质。 该树脂组合物可以用作木质纤维素或纤维素材料的粘合剂,其具有低甲醛排放和高强度的优良组合。 还描述了包含独特粘合剂组合的低甲醛排放木制品。
