Emulsion Stabilizer & Binder
Enwere ike iji PVA mee ihe dị ka colloid nchebe ma ọ bụ thickener maka emulsion polymerization nke vinyl acetate (Vac) ma ọ bụ Vac / acrylate.nwere njirimara ndị a: ezigbo 0adhesiveness; mmụba mbụ na ihicha ọnụego mgbe ejiri ya na-eji ya eme ihe;magburu onwe iguzogide mmanụ;ihe nkiri dị egwu.
