I-ejenti yokwelapha ubuso ibhekisela ku-reagent esetshenziselwa ukwelapha ubuso bento ukuze kufezwe injongo ethile, okuhlanganisa i-ejenti yokwelapha ubuso bensimbi, i-ejenti yokwelapha ubuso be-polytetrafluoroethylene kanye ne-ejenti yokwelapha ubuso be-silica gel.

I-ejenti yokwelapha ubuso bensimbi ibhekisela ebusweni bensimbi bokwelashwa okuhlukahlukene kwama-ejenti amakhemikhali abizwa ngegama elijwayelekile. Ukwelashwa kobuso bensimbi okuhlanganisa ukususa amafutha, ukususa ukugqwala, i-phosphate, ukuvimbela ukugqwala kanye nokunye ukwelashwa kwangaphambi kwesisekelo, kungokwezobuchwepheshe bokumboza insimbi, ubuchwepheshe bokuvikela insimbi okufanele bulungiselelwe, ikhwalithi yokwelashwa kwangaphambi kwesisekelo inethonya elikhulu ekulungiseleleni ukugqoka okulandelayo kanye nokusetshenziswa kwensimbi.

Isibonelo, i-BM-QY510 uhlobo lwe-fluid low foam, olungenayo i-phosphorus futhi olususa amafutha aqinile anobungani nemvelo. Ingasusa uwoyela onzima, i-polish kanye noketshezi olusebenzayo lwensimbi ebusweni bensimbi, insimbi kanye nensimbi engagqwali ngokusebenzisa ishawa noma i-flood stain esezingeni eliphezulu.
