There is a shortage of valuable wood species in the world. One of the easiest and affordable ways to replace is to create glued products from scarce wood species by gluing oversized blanks. Products made of glued blanks are not inferior to the products made of solid wood in quality and properties. These products have the properties of rare wood species. However, growing demand on the quality of glued products constantly challenge technologists to increase the strength of adhesive joints. This problem can be solved in several ways: development of new bonding technologies, creation of special adhesives for a specific task and modification of known adhesives. The aim of the research is to increase the adhesive strength of wood due to decrease of adhesive viscosity and decrease in wetting angle. It is achieved due to directional effects of combined physical field to resin. Urea-formaldehyde resin and oak wood specimens have been considered as the object of the research. As a result of the resin modification, strength of the adhesive joint along the fibers increased by 2 times (196%), while the values of the viscosity and wetting edge angle were reduced by 62% and 82%, respectively.

世界上珍贵的木材品种短缺。最简单且经济实惠的替代方法之一是通过胶合超大尺寸的坯料，从稀有的木材物种中制造胶合产品。用胶合板制成的产品在质量和性能上并不逊色于实木制成的产品。这些产品具有稀有木材的特性。然而，对胶合产品质量不断增长的需求不断挑战技术人员来提高胶接接头的强度。这个问题可以通过多种方式解决：开发新的粘合技术、为特定任务创建特殊粘合剂以及改进已知粘合剂。该研究的目的是通过降低粘合剂粘度和减小润湿角来提高木材的粘合强度。它是由于组合物理场对树脂的定向效应而实现的。脲醛树脂和橡木标本被认为是研究的对象。由于树脂改性，沿纤维的粘合接头强度增加了 2 倍（196%），而粘度和润湿边缘角的值分别降低了 62% 和 82%。
