BANI shows a high level of compatibility and wide range of mixing ratio with many kinds of resins* due to the lower molecular type of imide resin. BANI's character can easily achive the modification and/or denaturation of resins. *Phenol resin, epoxy resin, silicone resin, fluoric resin, thermoplastic polyamide, etc.
As shown in Table 3, BANI shows the excellent chemical resistance after curing.
