Iipeyinti zoshishino ezisekelwe emanzini zisebenzisa amanzi kakhulu njengesinyibilikisi sazo. Ngokungafaniyo neepeyinti ezisekelwe kwioyile, iipeyinti zoshishino ezisekelwe emanzini azinasidingo sezinyibilikisi ezifana nee-curing agents kunye nezithina. Ngenxa yokuba iingubo zoshishino ezisekelwe emanzini azitshi kwaye aziqhumi, ziphilile kwaye ziluhlaza, kwaye ziphantsi kwe-VOC, zisetyenziswa kakhulu kwiindawo zoshishino, ezifana neebhulorho, izakhiwo zentsimbi, izithuthi zorhwebo, oomatshini bokwakha, amandla omoya e-petrochemical kunye nezinye iindawo.

Abavelisi bepeyinti esekwe emanzini badla ngokwahlula iipeyinti zoshishino ezisekwe emanzini zibe ziipeyinti ezisekwe emanzini ze-alkyd, iipeyinti ezisekwe emanzini ze-acrylic, iipeyinti ezisekwe emanzini ze-epoxy, iipeyinti ezisekwe emanzini ze-acrylic, iipeyinti ezisekwe emanzini ze-amino, kunye neepeyinti ezisekwe emanzini ezi-inorganic zinc. Zingahlulwa zibe ziipeyinti ezizimisayo, uhlobo lokubhaka kunye nohlobo lwe-dip coating.

Ipeyinti ye-alkyd resin esekwe emanzini ineempawu zokomisa ngokukhawuleza kunye nokusebenza kakuhle kokukhusela, kwaye ingasetyenziselwa ukuvala okuphantsi kwe-substrates zesinyithi. Ukuvala kungafakwa nge-dip coating, i-spray coating, i-spray coating kunye nezinye iindlela. Olu hlobo lusetyenziswa kakhulu kwi-dip coating yeebrakethi zefenitshala, i-automobile chassis, kunye ne-automobile leaf springs, kwaye ifanelekile ngakumbi kwi-protective coating yomphezulu wentsimbi ethunyelwa kwamanye amazwe.

Eyona nto iphambili ngepeyinti ye-acrylic esekwe emanzini kukuba inamathela kakuhle kwaye ayizukuyenza nzulu imibala, kodwa ayinakuguguleka kakuhle kwaye ayixhathisi ngamakhemikhali. Ngenxa yexabiso layo eliphantsi kunye nomxholo ophantsi wobuchwephesha, isetyenziswa kakhulu kwizakhiwo zentsimbi ezine-gloss ephantsi kunye nefuthe lokuhombisa.

Ipeyinti ye-epoxy resin esekwe emanzini ayinazo izinto ezinobungozi ezifana ne-benzene, i-formaldehyde, i-lead, i-mercury, njl. Inomxholo ophezulu oqinileyo, inamathela ngokuqinileyo, ukusebenza kakuhle kokulwa nokugqwala, kunye nokhuseleko olugqwesileyo lwemveliso kunye nokumelana nobushushu. Uphuhliso kunye nokusetyenziswa kwayo kuphuhliso lwangoku lweengubo zaselwandle.

Iipeyinti zoshishino zenziwe ikakhulu ngee-amino ezisekelwe emanzini kunye nee-alkyd compounds. Ukongeza kwiimpawu zepeyinti esekwe emanzini, le peyinti esekwe emanzini inokukhanya okugqwesileyo kunye nokugcwala, kwaye ukusebenza kwayo akwahlukanga kwi-amino yendabuko. Nangona kunjalo, kufuneka ibhakwe ngexesha lokwakhiwa, nto leyo ekwayingxaki yale mveliso.
