Technical specification

Use:
SHY—9601/9602/9603 are curing agents for epoxy resins, and mainly used in electronics, electric work and encapsulation industries. It is the major base metal for mutual inductors, insulated paint, high-voltage electrical apparatus and glass reinforced plastics.
Storage & transportation:
Closed tight, protect against moisture; shelf life at room temperature is 1 yr. If absorbed moisture, it will generate precipitation.Then heat it at around 140℃ for recovery, and its property will not be affected.
