The aim of the study was to determine in the methodological aspect the suitability of the selected cyanoacrylate adhesives to conduct adherence investigations of foils and laminates to the surface of particleboard and MDF. Cognitive aspect was to determine in a model system for solidified adhesive’s layers the surface free energy, taking into account the assumptions of the adsorption theory of adhesion. Furthermore evaluated the effect of selected solvent adhesion promoters (primers) on the course of a parameter of the contact angle and γs values. For the experiments board elements covered with PVC foil and laminate under industrial conditions were selected. The investigation of contact angle (θ) of the surfaces were performed according to the procedure described in PN EN 828 standard. Free surface energy with the dispersion and polar shares were calculated according to literature data. Adherence tests were performed according to EN 4624 procedure.
It was stated among others that, tested in a model system on the surface of the glass substrate, both cyanoacrylate adhesives characterized by similar adhesion properties. Adhesion promoters not resulted in significant changes on the surface free energy, affecting only the increase on their polar share. In the procedure for testing the adherence PVC foil to MDF board, for operation of measuring stamps included in the experiment both cyanoacrylate adhesives can be recommended.
