Mapulogalamu
THPA nthawi zambiri imagwiritsidwa ntchito popanga utomoni wa alkyd ndi unsaturated polyester, zokutira ndi machiritso a epoxy resins, komanso amagwiritsidwa ntchito mu mankhwala ophera tizirombo, sulfide regulator, plasticizers, surfactant, alkyd resin modifier, mankhwala ophera tizilombo ndi yaiwisi. zipangizo za mankhwala.
Monga zipangizo zopangira polyester yosakanizidwa, THPA makamaka imapangitsa kuti ntchito yowumitsa mpweya ikhale yabwino kwambiri.
