Coatings are often applied in the materials industry to impart hydrophobic properties to the produced materials. Commonly used coatings contain plastics as well as perfluorinated compounds. Coatings based on natural wax, such as rapeseed, soy, palm or beeswax constitute a key bioalternative. Wax is characterised by high hydrophobicity and is also considered biodegradable. Wax coating constitutes a protective layer that undergoes biodegradation after a certain amount of time. This paper presents the results of studies concerning the development of a wax coating characterised by a coarse microstructure that increases the water resistance, and an appropriate susceptibility to biodegradation. It was revealed that all the analysed coatings were susceptible to biodegradation. Palm wax has a significant effect on inhibiting the wax coating biodegradation rate given that its surface undergoes morphic changes due to the influence of biosurfactants secreted by bacteria. This increases the adhesion of organic and inorganic matter particles, and the layer thus established limits the diffusion of oxygen, enzymes and microorganisms to the wax coating.
