LAMINATING SYSTEM
RDR-2250 is a high temperature laminating system that cures at room temperature with post cure. It is extremely tough, has good dimensional stability with good heat distortion for tools requiring elevated temperatures.
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°F per min.
