  • Upon decomposition, QPAC®25 leaves less than 10 ppm ash residue, resulting in excellent mechanical and/or electrical properties
  • Low temperature decomposition is excellent for thermal sensitive materials and is more efficient than other binders
  • QPAC®25 has excellent green strength and results in high density final parts with better part structure
  • Decomposition can occur in a wide range of atmospheres including oxygen, hydrogen, air, nitrogen, argon and vacuum
