Nā noi
He mea waena organik, hoʻohana pinepine ʻia ʻo THPA i ka hana ʻana o nā resins polyester alkyd a me unsaturated, nā uhi a me ka mea hoʻōla no nā resins epoxy, a hoʻohana ʻia hoʻi i nā insecticides, sulfide regulator, plasticizers, surfactant, alkyd resin modifier, pesticides a me nā mea maka o nā lāʻau lapaʻau.
Ma ke ʻano he mea maka no ka hana ʻana o ka polyester unsaturated, ua hoʻomaikaʻi nui ʻo THPA i ka hana hoʻomaloʻo ea o nā resins. ʻOi aku ka maopopo o ka hana ʻana ma ka hana ʻana o ka putty resin kiʻekiʻe a me nā uhi hoʻomaloʻo ea.
Hoʻopili ʻana
