CONTACT ANGLE EVALUATION OF SUSTAINABLE ADHESIVE FORMULATIONS OVER LIGNOCELLULOSIC MATERIALS

The contact angle between a surface and a liquid drop can be studied to provide a measure, which indirectly establishes the wettability and degree of adhesiveness that the liquid has with the substrate-surface. Considering that wood is a lignocellulosic and porous material, the penetration of the liquid by its pores is an important factor in the interaction wood-adhesive formulations. Adhesive wetting on a surface includes: contact angle formation, dispersion and penetration. Both the penetration and the dispersion influence the contact angle to change as a function of time. In this work the relationship between the adhesive capacity of sustainable formulations with the variation in the contact angle over lignocellulosic surfaces is presented. The obtained results promote the description of the adhesive efficiency of the evaluated sustainable formulations, considering the use of substances from industrial by-products, such as depolymerized lignins from Kraft liquor for their implementation in lignocellulosic materials.
