Desmodur RE, e taʻua foi o le CAS 2422-91-5, o se faʻaogaina tele ma faʻaaogaina lautele.Ona o lona lelei lelei ma tulaga lelei, ua faʻaaogaina lautele i pisinisi eseese.I totonu o lenei tusiga, matou te suʻesuʻeina le faʻaogaina o Desmodur ma suʻesuʻe pe aisea e lauiloa ai i tagata gaosi oloa.
Desmodur RE o le aiga o diisocyanates aromatic, faʻaogaina lautele faʻaaogaina i le gaosiga o polyurethane coatings, faʻapipiʻi ma elastomers.E lanu samasama i le amber vai e aofia ai le faʻafefiloi o isomers faʻatasi ai ma fausaga kemikolo tutusa.O le mea autu o Desmodur RE o toluene diisocyanate (TDI), lea e faʻaaogaina lautele i le gaosiga o le polyurethane foam.
O se tasi o faʻaoga autu oDesmodur REo loʻo i totonu o le gaosiga o paʻu polyurethane.Polyurethane coatings e maua ai le puipuiga sili mai le pala, tau ma abrasion.Ua lauiloa i latou mo le maualuga o le tumau ma le lelei o le faatinoga i siosiomaga faigata.Desmodur RE o se vaega autu i nei faʻapipiʻi faʻapipiʻi, tuʻuina atu ia i latou le faʻateleina o le maaa, faʻapipiʻi ma le faʻamaʻi.
O le isi faʻaoga taua a Desmodur RE o le gaosiga o mea faʻapipiʻi polyurethane.Polyurethane adhesives o loʻo faʻaaogaina lautele i fale taʻavale, faufale ma meaafale ona o lo latou malosi sili atu ma le agavaʻa.Desmodur RE faʻaleleia le malosi o fusi o polyurethane adhesives, faʻatagaina i latou e pipii i mea eseese e pei o uʻamea, palasitika ma laupapa.O le mea lea e lelei ai mo lamination, faʻapipiʻi ma faʻamaufaʻailoga.
Desmodur RE faʻaaogaina foi i le gaosiga o polyurethane elastomers.Polyurethane elastomers o loʻo faʻaalia ai mea faʻainisinia sili ona lelei e pei o le maualuga o le elasticity, teteʻe o loimata ma le faʻafefe.E fa'aaogaina i pisinisi e pei o seevae, ta'avale ma fale gaosi oloa.Desmodur RE e taua tele i le tuʻufaʻatasia o nei elastomers, ma tuʻuina atu ia i latou le malosi sili ona malosi ma le faʻalauteleina o mea.
E lē gata i lea,Desmodur REua lauiloa ona o lona vave faamalolo.O lona uiga e mafai ona vave feso'ota'i ma polyols e fausia ai se feso'ota'iga polyurethane malosi.Fa'ato'a vave e mana'omia tele i alamanuia e mana'omia ai taimi vave fa'aliliu, pei o fale ta'avale po'o fale faufale.E le gata i lea, o Desmodur RE o loʻo i ai le fesoʻotaʻiga lelei ma le tele o polyols, e mafai ai e le au gaosi oloa ona faʻafetaui meatotino oa latou oloa i manaoga faʻapitoa.
I le faaiuga, Desmodur RE (CAS 2422-91-5) o se faʻaogaina lautele faʻaoga faʻatasi ma faʻaoga lautele i alamanuia e pei o paʻu, faʻapipiʻi ma elastomers.O ona uiga tulaga ese, e aofia ai le faʻaleleia atili o le maaa, faʻapipiʻi ma le vave faʻamalolo, avea ma filifiliga lauiloa i le au gaosi oloa.Pe o le tuʻuina atu o le puipuiga o le pala e ala i le polyurethane coatings, ausiaina o fusi malosi i mea faʻapipiʻi, poʻo le faʻaleleia o mea faʻainisinia o elastomers, Desmodur RE ua faʻamaonia e avea o se vaega taua i le gaosiga o mea e sili ona lelei.
