Abstract
Adhesion of foils to MDF board. The article deals with adhesion of foils to MDF board. Foiled furniture parts made from MDF board are one of the alternatives of coating. The aim of our work was to study the effect of adhesive spread on adhesion of two types of foils (PVC and PET). Two-component polyurethane adhesive was used. The adhesive spread was of the recommended amount, or the amount reduced by 50 %, or increased by 50 %. Boards with both types of foils were pressed at the same pressing mode. Adhesion was determined by the Pull- off test for adhesion. After pull of strength measurement, the metal discs were analysed and the place of failure was determined. For both types of foils, the failure was in the adhesive layer. The surfaces with PET foil showed higher adhesion. The highest adhesion was measured on the specimens with the recommended adhesive spread for both PET and PVC foils. Both reduction and increase in the adhesive spread resulted in reduced adhesion of foils to MDF board. Keywords:
