Durability testing of waterborne wood coatings

U ovom diplomskom radu ispitivala se postojanost polutransparentnih i pokrivnih vodenih premaza različitoga cjenovnog razreda koji se primjenjuju za drvene prozore. Tri sustava polutransparentnih i tri sustava pokrivnih vodenih premaza uspoređivala su se nakon ubrzanog izlaganja u QUV uređaju. Cilj ovog diplomskog rada bio je procijeniti postojanost premaza različitih proizvođača i vidjeti da li veća cijena premaza znači i njegova bolja svojstva. U radu su korišteni sustavi premaza nižeg, srednjeg i višeg cjenovnog razreda.The durability of semi-transparent and opaque waterborne coating systems for wooden windows was examined in this graduate thesis. Three semi-transparent and three opaque waterborne coating systems were evluated after accelerated exposure in QUV accelerated weathering tester. The aim of this thesis was to assess the durability of the different coating systems and to establish if the higher price of coating system means the better performance. The coating systems used in this work were of lower, middle and higher price rang
