Wood Adhesives and Bonding Theory

Abstract

In this last century, world had grown faster than before; now people need more furniture than in the past century. More furniture means, more particleboards and more adhesives. Wood adhesives are used in every step of furniture manufacturing. Wood adhesives aim to bond wooden materials with each other or with different materials. Today, production with a faster pace is more important. Furniture production lines could be more productive with fast curing glues. Wood adhesives are used in more than 70% of wood products today in the world. The main reason is their use in gluing furniture joints and wood composite materials. In this chapter, readers can find four different topics: (1) technical properties of wood adhesives, (2) environment friendly adhesives, (3) semisynthetic adhesives, and (4) synthetic adhesives.

Determining the effect of the composition of an aluminosilicate binder on the rheotechnological properties of adhesives for wood

“…We determined a surface tension coefficient for the aluminosilicate adhesives by a drop separation method [5,33]:…”

“…Another advantage of glued structures is the utilization of substandard wood [3]. Wood gluing mainly involve organic adhesives based on polyvinyl acetate emulsions that has water resistance indicators of D2...D4 [4], as well as phenol-formaldehyde [5], acrylic [6], epoxy [7], polyurethane [8], and others.…”

Disposable and Flexible Electrochemical Paper‐based Analytical Devices Using Low‐cost Conductive Ink

“…Polyvinyl alcohol (PVA) and polyvinyl acetate (PVAc) are the main compounds use in home adhesives and they are suitable for attaching to porous materials such as paper or wood [27,28]. PVA resins present a long shelf life at room temperature and produce cured films that are waterproof and mechanically resistant [29].…”

Effect of Glue Spreads on the Structural Properties of Laminated Veneer Lumber from Spindleless Rotary Veneers Recovered from Short Rotation Hevea Plantation Logs

“…Rubberwood veneers peeled and recovered from short rotation Hevea plantation logs using spindleless lathe have deep lathe checks and rough surfaces, which might cause the adhesive to overpenetrate and dry out at the glueline [1]. Over-penetration of adhesive into wood results in insufficient adhesive remaining in the glueline to bridge between wood surfaces [2]. The presence of insufficient adhesive in the glueline decreased cohesion strength, resulting in a thin and starved glueline [3].…”
