Talosaga

O diamines o se vasega taua o vailaʻau e faʻaaogaina lautele o ni mea mata, ni vailaʻau faʻalava poʻo ni oloa. Mo se faʻataʻitaʻiga, o diamines o ni vaega taua o le fausaga i le faʻaputuga o le polyamide ma isi tali o le polymerization condensation. O le N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) o se vailaʻau faʻalava taua, e faʻaaogaina mo se faʻataʻitaʻiga i le sauniuniga faʻapisinisi o lubricants. E le gata i lea, o le DMAPA e faʻaaogaina o se mea mata mo le sauniuniga o coagulants ma e tatau ona i ai ona uiga e teteʻe ai i le pala.
