Influence of Different Mixing Ratios of Adhesives for Wood Bondline Quality

Authors: Jan Vanerek, Anna Benesova, Pavel Rovnanik

Abstract:

The research study was based on an evaluation of the ability of glued test samples to pass the criterion of sufficient bondline adhesion under the exposure conditions defined in EN 302- 1. Additionally, an infrared spectroscopic analysis of the evaluated adhesives (phenol-resorcinol-formaldehyde PRF and melamine-ureaformaldehyde MUF) with different mix ratios was carried out to evaluate the possible effects of a faulty technological process.

Keywords: Adhesives, bondline, durability, timber.
