Case 1: An aerospace company used Factory Supply 4,4′ - methylenebis(n,n - diglycidylaniline) in the production of carbon fiber - reinforced epoxy composites for aircraft wing parts. By using this product as a curing agent, they were able to increase the strength - to - weight ratio of the wing parts by 20%. The cured composites also showed better resistance to fatigue under long - term flight conditions, which significantly improved the safety and performance of the aircraft.
Case 2: An electronics manufacturer applied this product in the encapsulation of printed circuit boards (PCBs). After encapsulation, the PCBs showed a significant improvement in moisture resistance. The failure rate of the PCBs due to moisture - induced short - circuits was reduced from 5% to less than 1%, which greatly improved the reliability of their electronic products.
