Description
HIGH TEMPERATURE CLEAR
(Clear and Rigid)
LAMINATING SYSTEM
RDR-3250 is an unfilled clear epoxy room temperature curing laminating system used in high temperature and room temperature applications. This system is tough, strong, has good heat distortion, chemical resistance and excellent adhesive qualities. As with most high temperature systems, it will achieve a demoldable state overnight @ ambient temperature. In some instances, tools may be used without post cure. However, for most uses at elevated temperature, post cure is recommended.
Upon Completion, the tool should be allowed to cure at ambient temperature for 24 hrs. At that point, apply an oven cure, cycle should be 50°F per hour(tool temperature, not air temperature). Not more than 5° per min.
