Another Look at BTDA™

Due to increasing design complexity of consumer/industrial electronics and related materials, formulators are regularly challenged to meet the demands of in-service thermal and dielectric properties of epoxy systems. 3,3',4,4'-Benzophenonetetracarboxylic dianhydride (BTDA™), a workhorse dianhydride since its inception in the late 1960s, has secured its role as a thermal curative for epoxy resins. However, monoanhydrides became the preferred alternative over the years, due to liquid compositions and simpler dosing requirements. This is especially prevalent with modern epoxy formulators focused on newer technologies.

This presentation will serve to reintroduce BTDA and its everyday benefits including:

  • Multiple functionality for building traditional systems or new hybrids
  • Purity and particle size to meet specific requirements
  • Low mix viscosity for easier incorporation of fillers, fibers and additives
  • Variable pot life for optimal processing
  • Variable cure schedules to accommodate existing heating equipment
  • Enhanced thermal resistance of fabricated parts
Key Take-Aways:
  • BTDA is a workhorse dianhydride with a long track record as a thermal curative for epoxy resins
  • When correctly formulated, epoxy systems cured with BTDA obtain exceptional levels of Tg and heat stability
  • BTDA can be used in blends with monoanhyrides to tailor performance properties
