What is Diallyl bisphenol A?
The Uses of Diallyl bisphenol A
diallyl bisphenol A is a kind of modified monomer of thermosetting resin which is mainly used in the modifying and toughening of bismaleimide resin, epoxy resin, phenolic resin etc., and it can enhance the toughness of thermosetting resin greatly. It also can be used as actively diluent of thermosetting resin. The adhesion strength between metal can be further improved when used in rubber.
General Description
2,2′-Diallylbisphenol A (DABA) is a diallyl based epoxy modification agent that blends with the resin to improve the mechanical property of the epoxy material. It is majorly used in novalac based resins, which can be further cured with bismaleimides (BMI) for aerospace, electronics and wireless communication based applications.
