Applications
s intermedium organicum, THPA in productione alkydarum et resinarum nonsaturatae polyestri soleat, fucis et curatione agentis ad resinas epoxy, ac etiam in insecticidis, sulfide moderatoris, plastici, surfactantis, resinae alkydae determinatoris, pesticidis et crudi. materias pharmaceuticas.
Sicut materias rudis ad polyester nonaturatum producendum, THPA maxime emendavit aerem resinae siccitatis effectum. Effectus manifestior est praesertim in productione resinae pustulae et aeris siccitatis coatings altae gradus.
