Technical Details & Test Data
- Molding Suggestions
QC 2550 can be molded at temperatures in the range of 260-310°F, with 280°F suggested as a starting point. Cure times will be dependent on molding temperature and part thickness and will typically be 5-10 minutes. Detailed molding suggestions are available on request. Cool molded parts at ambient temperature. A cooling fixture may be needed depending on part thickness and geometry. A breath cycle is recommended during mold process to allow for moisture generated during cure reaction to escape.
Packaging & Availability
- Packaging Type
Storage & Handling
- Shelf Life
- 2 Months (40°F), 6 Months at 10°F
- Precautions
QC 2550 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.
