1, uthuli olungaphezulu nokungcola ngensipho yokuthambisa ebuthakathaka nokugeza ngamanzi afudumele.

2, uphawu lokuhweba, ifilimu ngamanzi afudumele kanye okokuhlanza okubuthakathaka ukugeza.
Ukwakheka kwe-binder kukhuhla ngotshwala noma nge-organic solvent.

3, amafutha angaphezulu, amafutha, ukungcoliswa kwamafutha okugcoba, sula ngendwangu ethambile, insimbi engagqwali enombala nge-detergent engathathi hlangothi noma isixazululo se-ammonia noma ngesihlanzi esikhethekile sokugeza.
