Applications
THPA inowanzo shandiswa mukugadzira alkyd uye unsaturated polyester resin, machira uye mumiririri wekurapa epoxy resin, uye inoshandiswawo mumishonga inouraya zvipembenene, sulfide regulator, plasticizers, surfactant, alkyd resin modifier, mishonga yezvipembenene uye mbishi. zvinhu zvemishonga.
Sezvinhu zvakasvibirira zvekugadzira polyester isina unsaturated, THPA yakanyanya kuvandudza kushanda kwemhepo-kuomesa resin.Kuita kunonyanya kuoneka kunyanya mukugadzirwa kwepamusoro-grade resin putty uye air-drying coatings.
