Designer Molecules BMI-689 Liquid Bismaleimide
Categories: Fluid

Material Notes: Description: BMI-689 is a unique low viscosity liquid bismaleimide based on a non-hydrogenated dimer diamine backbone. It can be homo-cured via UV or free radical initiators to form tough, hydrophobic, cross-linked polyimides. The material has excellent low pH hydrolytic resistance and thermal stability. The amorphous nature of this BMI allows it to be used in a variety of applications including mixed cure systems (e.g. epoxy and BMI), mixed BMI systems or where a low viscosity, free radical cured resin is required. It is soluble in most aromatic and aliphatic solvents such as toluene, xylene, NMP, etc.

Highlights:

  • Low viscosity liquid BMI
  • High adhesion to various substrates
  • Hydrophobic
  • Superior thermal stability
