Technical Details & Test Data
- Molding Suggestions
QC-7810FR can be molded over a range of temperatures and pressures. For part thickness of 0.5 inches or less, molding temperatures of 280 to 320°F are suggested as a starting point, with molding pressure of 300 to 1000 psi. Cure time will depend on molding temperature and part thickness. Parts will normally be rubbery on ejection from the mold.
Packaging & Availability

Storage & Handling
- Shelf Life
- 2 Months (75°F)
- Precautions
QC 7810FR contains glass fibers and should be handled carefully in order to minimize skin contact. Molding areas should be well ventilated to minimize exposure to fumes. Presses must be provided with local exhaust to remove vapors from work areas. If adequate ventilation is not available, a respirator approved for removing organic vapor must be used.
