Applications
s medium organicum, THPA in productione resinae alkydae et nonassatae polyesterae, fucata et agentis ad resinas epoxy curandas, atque etiam in insecticidis, sulfide moderatoris, plastici, surfactantis, resinae alkydae determinatoris, pesticidis et crudi. materias pharmaceuticas.
Ut materias rudis ad polyester insaturatum producendum, THPA maxime emendavit resinae aeris exsiccatio. Effectus manifestior est praesertim in productione summi gradus resinae puttae et aeris siccitatis coatings.
