MCDEA 4,4′-Methylene-Bis(3-Chloro-2,6-Diethylaniline) CAS 106246-33-7

4,4'-Methylene-Bis (3-Chloro-2,6-Diethylaniline) (Curing Agent Chain Extender MCDEA) ni ikomoka kuri MDA muri Vivo, Elastomeri za PU zifite imiterere myiza zishobora gutegurwa hamwe na TDI Prepolymers. Yo hamwe na MOCA ijyanye nayo, uruvange rwa 740M rushobora kunoza imikorere ya PU Elastomeri kandi rukagira ingaruka nziza ku nyongeramusaruro. Mu buryo bwa PU Casting, Spraying, RIM n'ubundi buryo bw'ikoranabuhanga, ndetse n'ibicuruzwa bya microporous, TPU, Adhesives, Coating Agents n'ibindi bicuruzwa bikoreshwa cyane mu gutegura. Iki gicuruzwa ntabwo kirimo uburozi kandi cyemewe na EU mu bihe byo kurya no kunywa ibiyobyabwenge.

Iki gicuruzwa gihuye neza kandi gihuye neza na TDI Prepolymers. Ibicuruzwa bya PU byateguwe bifite imiterere myiza cyane. Imiterere ya fiziki n'ingufu ishobora gukoreshwa mu gusuka, gutera, RIM n'izindi koranabuhanga mu gutunganya. Ikoreshwa; mu gutegura PU Elastomers, ibikoresho bya mikorobe, kole, ibikoresho byo gusiga, nibindi. Bikoreshwa cyane2. Iki gicuruzwa gishobora kandi gukoreshwa nk'ikintu gikiza Epoxy Resin no gutegura Polyimide, nibindi.
