Riƙewar ruwa da daidaito:
Ɗaya daga cikin manyan fa'idodin haɗawa da HPMC a cikin kayan aikin bango shine kyawawan kaddarorin riƙon ruwa. HPMC shine polymer hydrophilic, ma'ana yana da alaƙa mai ƙarfi ga ruwa. Lokacin da aka ƙara zuwa bangon bango, HPMC yana samar da fim ɗin da ke riƙe da ruwa a kusa da barbashi na siminti, yana hana ruwa daga ƙura da sauri yayin aikin warkewa.
Ƙarfin HPMC don riƙe danshi a cikin mahaɗin yana da fa'idodi da yawa don aikace-aikacen putty na bango.
