Za zunanjo uporabo se v svetu namesto naravnega lesa uvaja uporaba modificiranega lesa, ki je dimenzijsko stabilnejši. V literaturi pa je še vedno zelo malo podatkov o sistemih modificiran les - površinski premaz. Zato je bil cilj naše raziskave preučiti lastnosti premazov za zunanjo uporabo na termično modificiranem lesu rdečega bora in nekaterih drugih lesnih substratih. Izvedli smo umetno pospešeno staranje nepremazanih in premazanih vzorcev ter ugotavljali vplive tega postopka na lastnosti, kot so oprijemnost premaza, barva, sijaj, kontaktni kot za vodo ter prepustnost premaza za vodno paro in tekočo vodo. Ugotovili smo, da je sistem "termično modificiran rdeči bor - premaz" primerljiv s sistemom "nemodificiran les - premaz".

• Title: Influence of atrificial accelerated weathering on properties of surface coatings on non-modified and modified wood

Abstract

Due to its increased dimensional stability, modified wood is suited for outside applications. Because the systems "exterior surface coatings - modified wood" have not been studied thoroughly up to now, the aim of our workwas to investigate some properties of exterior finishes on thermally modified pine wood and on some other wooden substrates. We carried out artificial accelerated aging of unpainted and painted samples and considered the influence of aging procedure on some properties of the coatings like adhesion, colour, gloss, wettability and water-vapour and liquid water permeability. The results showed that the system "thermally modified pine wood- surface coating" is comparable to conventional systems "non-modified wood - surface coating".
