Benefits
- Upon decomposition, QPAC®40 leaves less than 10 ppm ash residue, resulting in very good mechanical and/or electrical properties
- QPAC®40 has superior green strength and results in high density final parts with better part structure
- Low temperature decomposition is exceptional for thermal sensitive materials and is more efficient than other binders
- Decomposition can occur in a wide range of atmospheres including air, argon, oxygen, hydrogen, nitrogen and vacuum
