Daim ntawv thov
s cov organic nruab nrab, THPA feem ntau yog siv los tsim cov alkyd thiab unsaturated polyester resins, coatings thiab curing tus neeg sawv cev rau epoxy resins, thiab kuj siv nyob rau hauv cov tshuaj tua kab, sulfide regulator, plasticizers, surfactant, alkyd resin modifier, tshuaj tua kab thiab raw. cov ntaub ntawv ntawm pharmaceuticals.
Raws li raw cov ntaub ntawv rau zus tau tej cov polyester unsaturated, THPA mas txhim kho cov huab cua-drying kev ua tau zoo ntawm resins.Qhov kev ua tau zoo dua tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov high-qib resin putty thiab cua-drying txheej.
