Hexahydrophthalic Anhydride HHPA CAS 85-42-7
Hexahydrophthalic Anhydride (HHPA), yokhala ndi nambala ya CAS 85-42-7, ndi mankhwala ochiritsira a aliphatic epoxy resin omwe amagwiritsidwa ntchito kwambiri. Ndi opanda mtundu, savutika ndi nyengo, ali ndi kukhuthala kochepa ndipo alibe chikasu. Ma Alicyclic compounds alibe mphete za benzene, amalimbana ndi kuwala kwa ultraviolet ndipo ali ndi kukana kwabwino kwa nyengo popanda chikasu; kukhuthala kwawo kosungunuka ndi kochepa ndipo kukonzedwa kwake ndi kwabwino; amatha kusungunuka kukhala hexahydro-2-methylphenylphthalic acid akakumana ndi madzi (omwe amakhudzidwa ndi kuyamwa kwa chinyezi).
| Chinthu | Mafotokozedwe |

| Mtundu wa Hazen (Pt-Co) | ≤50 |
| Zamkati (%) | ≥99.0 |
| Malo oziziritsa (℃) | 34.0-38.0 |
| Mtengo wa ayodini (Ig/100g) | ≤1.0 |
Chothandizira kuchiritsa utomoni wa epoxy (ntchito yayikulu)
Kuphika kwa epoxy panja kosagwedezeka ndi nyengo, kuponyera kwamagetsi, kuponyera koteteza kutentha, pansi pa epoxy, zokongoletsera zowonekera bwino za epoxy; chinthu chotsukidwa chimakhala chowala kwambiri, cholimba bwino kwambiri pa nyengo komanso choletsa chikasu, choteteza bwino kwambiri chamagetsi, komanso mphamvu yayikulu yamakina.
Zophimba / Inki
Zophimba ufa zosagwedezeka ndi nyengo, ma varnish okhala ndi zosungunulira, ma resini a UV, zinthu zopangira polyester zosakhuta. Zina
Mapulasitiki, zoletsa dzimbiri, zothamangitsa tizilombo, polyester polyols, zomatira pakati.
