Purpose: The aim of the research was to determine the most favourable fluoropolymer coatings, deposited on the surface of aluminium moulds, which will be used to share improvements in automotive sectors. Design/methodology/approach: The paper presents the results of the coatings thickness and surface roughness measurements, AFM analysis, contact angle measurements and surface free energy calculation, wear test and adhesion force measurement of three fluoropolymer coatings. Findings: On the basis of the investigation, it can be stated that the properties of the tested coating and their adhesion to the aluminium substrate are different. Based on the obtained results it can be concluded that the coating named Coat_134 was characterized by the optimum properties - well anti-adhesion properties and good mechanical properties. Research limitations/implications: Coating must be applied on the surface of injection tools, with complex shape and wide range of dimensions. Practical implications: Injection moulds for polyurethane foam, reduction of release agent consumption. Originality/value: The paper presents comparative research of fluoropolymer coatings in order to determinate adhesion to polyurethane foam with low density.
