Appli­ca­tion

1. Syn­the­sis of ketone anhy­dride, poly­imides, used in foams, paints, films, fibers, com­pos­ites, BTDA con­tain­ing poly­imides have excel­lent ther­mal oxida­tive sta­bil­i­ty, strength, sol­vent resis­tance, flex­i­bil­i­ty. 2. As an excel­lent epoxy cur­ing agent, the resin has a high tem­per­a­ture sta­bil­i­ty, excel­lent elec­tri­cal prop­er­ties, chem­i­cal resis­tance, sol­vent resis­tance with BTDA. 3. In the poly­ester resin, ester for­mu­la­tions, ure­thane resin, alkyd resin, poly­ben­z­im­i­da­zole pyrroli­done and oth­er for­mu­la­tions, one BTDA anhy­dride can be added excel­lent high tem­per­a­ture and oxida­tive sta­bil­i­ty.
