Abstract

U radu se prikazuje istraživanje utjecaja UV stabilizatora (dihidroksi-benzofenona i nano cinkova oksida) na razgradnju vodenoga akrilnog premaza na bukovini koja je bila izložena vremenskim utjecajima. Uzorci drva premazani su kistom, a potom su šest mjeseci prirodno izloženi vremenskim utjecajima. Dobiveni su rezultati pokazali da nano cinkov oksid smanjuje promjenu boje i pojavu plijesni na površini izloženih uzoraka. Međutim, rezultati kontaktnog kuta, adhezije, kolorimetrije i FTIR analize potvrđuju da dihidroksi-benzofenon nije učinkovit u sprečavanju razgradnje premazanog drva.
