Umgubo wepolymer odispersible uphucula ubuthathaka bodaka lwesamente lwesintu olufana nokuqhawuka kunye nemodyuli enwebekayo ephezulu, kwaye inika udaka lwesamente ukuguquguquka okungcono kunye namandla okuqina okubopha ukuxhathisa kunye nokulibazisa ukubunjwa kweentanda kwisamente yodaka. Ekubeni i-polymer kunye nodaka zenza i-interpenetrating network structure, ifilimu ye-polymer eqhubekayo yenziwa kwiipores, ezomeleza ukudibanisa phakathi kwee-aggregates kunye neebhloko ezinye ze-pores kumdaka. Ngoko ke, ukusebenza kodaka oluqinisiweyo olulungisiweyo luphuculwe kakhulu kunodaka lwesamente.
Njengezinto eziyimfuneko zokuhombisa ekuhombiseni, i-putty eludongeni sisiseko somgangatho wodonga kunye nokulungiswa, kwaye isiseko esihle seminye imihlobiso. Umphezulu wodonga unokugcinwa kakuhle kwaye ufanayo ngokusebenzisa i-putty eludongeni, ukwenzela ukuba iprojekthi yokuhlobisa elandelayo iqhutywe ngcono. I-Wall putty ngokuqhelekileyo yenziwe ngezinto ezisisiseko, isihluzi, amanzi kunye nezongezo. Yeyiphi imisebenzi ephambili yomgubo wepolymer ephinda ihlakazwe njengesona songezo esiphambili kwiputty eludongeni?
