PnB ikoreshwa cyane nkibikoresho byoza ibintu byanduye cyane. Irashobora gushonga amavuta yo guhuza hamwe namavuta neza kandi ikabigira muburyo bwurugo ninganda. Igice kimwe gishobora gushonga mumazi, PnB irashobora gushonga cyane hamwe nibisabwa kuburyo bukurikira:

① nk'isuku yo mu rugo n'inganda, kuvanaho amavuta n'irangi, umukozi uhuza hamwe no gukemura ibyuma kandi bisukura hejuru;

② nkibikorwa bifatika byo guhuza no kugabanya amazi agabanya amazi;

③ nkibikoresho bifatika byo gusiga amarangi ashingiye kumazi;

④ nkibikorwa bifatika byo gusiga irangi;

⑤ nkibikoresho bya chimique hagati ya ester, solvent na plastizer.

DPnB
Gusaba mu gutwikira:nk'imwe mu mfashanyo nziza ikora firime yamabara ashingiye kumazi, DPnB irashobora gukoreshwa nka coagulant ya acrylic resin, fenylethylene acrylic resin na polyvinyl acetate itanga imikorere myiza yo gushushanya firime.
Gusaba mu isuku: birakoreshwa mubikoresho byogusukura cyane cyane kubisaba umuvuduko muke uhindagurika, nko kuvanaho ibishashara hamwe nogusukura hasi. Nkumuti mwiza wo gusiga amavuta hamwe namavuta, DPnB irashobora gukoreshwa nkibisiga irangi no kuvanaho amavuta yinyamaswa.
Ibindi bikorwa:DPnB irashobora kandi gukoreshwa mubicuruzwa byubuhinzi, kwisiga, wino ya elegitoroniki n’imyenda.
