- Precaution
QC 8705 contains glass fibers and should be handled carefully in order to minimize skin contact. Molding areasshould be well ventilated to minimize exposure to fumes. Presses must be provided with local exhaust to remove vaporsfrom work areas. If adequate ventilation is not available, a respirator approved for removing organic vapor must be used.

- Molding Suggestions
QC 8705 can be molded at temperaturesin 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.
