Cov ntawv thov
yog ib qho organic intermediate, THPA feem ntau yog siv rau hauv kev tsim cov alkyd thiab unsaturated polyester resins, coatings thiab tus neeg sawv cev rau epoxy resins, thiab kuj siv rau hauv cov tshuaj tua kab, sulfide regulator, plasticizers, surfactant, alkyd resin modifier, pesticides thiab cov ntaub ntawv raw ntawm cov tshuaj.
Ua cov khoom siv raw rau kev tsim cov polyester tsis muaj roj, THPA feem ntau txhim kho qhov kev ua tau zoo ntawm cov resins thaum cua qhuav. Qhov kev ua tau zoo pom tseeb dua tshwj xeeb tshaj yog hauv kev tsim cov resin putty zoo thiab cov txheej txheem cua qhuav.
