The objective of the research was to determine the influence of organosilicon compounds in preservative-protective systems on the selected properties of pine wood aimed for outdoor use. The investigations were made for biocide-free systems based on alkyd resin and natural oils modified with alkylalkoxy-, amino- and glycidoxysilanes. The special attention was paid on the influence of hydrophobic properties of wood surface on the resistance to abiotic and biotic factors. The scope of the research comprised of wood properties related to water soaking, durability to ageing including water and UV radiation as well as resistance to fungi and microfungi. The study has shown that wood surface treated with the preservative-protective systems containing silanes demonstrated increased hydrophobicity, hence higher resistance to abiotic and biotic factors. Favorable fungicidal properties of the systems allowed to consider them as a good alternative to the conventional preservatives containing fungicides.
