High Temperature Laminating (Aluminum) Slow - HTL-250

Category: Laminating
Ratio: 100pbw to 15pbw
Hardener: HT-9234
Description: HTL-250 Is a two component, high temperature lamination system that cures at room temperature with post cure. HTL-250 has excellent toughness, good dimensional stability with good heat distortion for tools requiring elevated temperatures. Post curing is recommended. Upon completion, the tool should be allowed to cure at ambient temperature. At that point apply an oven cure according to the following schedule: (This schedule is recommended for a tool which will be exposed to an operation temperature of 350°F).
