Aspiring for an integral use of wood raw material, many a research focuses on producing liquefied wood, and its use in different applications. Since gluing is one of the more important phases in wood working, we tried to make a new liquefied wood-based adhesive according to current ecological trends. We tested different combinations of liquefied wood-based adhesive mixtures with the addition of tannin and formalin. Adhesive quality was tested through establishing the shear strength of the adhesive bond. Pure liquefied wood reaches 64.5 % of required strength in durability class C1. We established that adding tannin only lowers strength and increases susceptibility to delamination in contact with water. Obviously tannin acts as filler since there was no straight improvement of adhesive bond. With the intention to achieve higher shear bond strength, we limited further tests to adhesive mixtures of liquefied wood and formalin. We raised the concentration up to 50 % formalin share and achieved 77 % of required strength according to durability class C1. We have established that formalin lowers adhesive bond susceptibility to water and reduces open times of adhesive mixture
