Pomaliza:

Guluu wa Polyvinyl Alcohol (PVA) ndi zomatira zosunthika zomwe zimagwiritsidwa ntchito mosiyanasiyana pazaluso ndi zamisiri, matabwa, kulongedza, nsalu, ndi mafakitale ena. Chikhalidwe chake chosungunuka m'madzi, chosakhala kawopsedwe, kusinthasintha, komanso kulumikizana mwamphamvu kumapangitsa kukhala chisankho chodziwika bwino chomangirira magawo osiyanasiyana m'magwiritsidwe osiyanasiyana.
