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.
