Tetramethylxylylene diisocyanate TMXDI (META) kounga teitei cas 2778-42-9
Ko te TMXDI (META) he monomer isocyanate aliphatic kei roto e rua ngā rōpū diisocyanate aliphatic tuatoru. He āhuatanga ahurei tēnei mahi ki te whakataurite ki ngā monomer kei roto te isocyanate tuatahi me te tuarua.
Ka whakamahia te monomer TMXDI hei hanga i ngā marara polyurethane kore-whakarewa. Ka taea te hanga i ēnei marara hei whakarato i te piri, te ngāwari, me te pakari ki ngā piripiri, ngā paninga, me ngā waituhi pumau-mārama, e mau ana i te wai.
1. Ngā marara polyurethane kore-whakarewa
2. Waterborne automotive OEM basecoat
3. Pane turanga whakahou waka wai-mai
4. Ngā paninga wai mō ngā kirihou me te rakau
5. He paninga wai mō te hiako
6. Ngā piripiri whakahohe wera
7. Ngā piripiri whakapiri
8. Waituhi wai
