    • 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.

    • An improved oxazolidine-based hardener to be used with a resorcinol resin or a tannin resin as the adhesive for the bonding of wood articles. Preferably, an oxazolidine is combined with particulate silica, and the resin is combined with a base such as NaOH. The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength requirements after the glue is cured at room temperature for under 24 hours. The improved hardener composition is storage stable; it can be prepared anytime before its use and, thus, eliminate the need to prepare a hardener immediately prior to the glue use. Since it is formaldehyde-free, it eliminates the safety issues associated with handling formaldehyde or paraformaldehyde. Also, the hardener provides flexible gel time or working time. Since the resins can be cured at room temperature, heating in an oven is not needed but could be used to reduce curing time. If radio frequencies are used to cure the resins, the exposure time can be reduced.
    • 与间苯二酚树脂或单宁树脂一起使用的改进的恶唑烷类固化剂作为粘合木制品的粘合剂。 优选将恶唑烷与颗粒二氧化硅组合,并将树脂与碱如NaOH混合。 基于改进的固化剂的粘合剂可以用于在木材在室温下固化24小时以后将木材颗粒粘合以通过湿强度要求。 改进的固化剂组合物储存稳定; 它可以在其使用之前随时准备,并因此消除在胶水使用之前立即制备固化剂的需要。 由于它是无甲醛,它消除了与处理甲醛或多聚甲醛有关的安全问题。 此外,固化剂提供灵活的凝胶时间或工作时间。 由于树脂可以在室温下固化,所以不需要在烘箱中进行加热,而可以用来减少固化时间。 如果使用无线电频率来固化树脂,则可以减少曝光时间。
