The following application properties of the copper - modified PBs were analysed – density, thickness swelling and water absorption after 2 h and 24 h, internal bond strength , bending strength – with the aim to determine whether or not they are affirming in a positive or negative sense with the used biocide . Through the linear correlatio ns and their coefficients of determination it was found that due to a higher amount of CuSO 4 .5H 2 O in MUF glues there significantly on 99.9% level changed only these two properties of PBs – thickness swelling after 2 hours increased ( TS 2h = 5.58 + 0.0 7 × w/w; R 2 = 0.27 ) and bending strength decreased ( BS = 11.39 – 0.10 × w/w ; R 2 = 0.49 ).
