***Step Post Cure required for constant high temperature service
Service Temperature: 200 - 300F Intermittent--dependant on hardener used
**Heat resistance is determined by intermediate of constant temperature factor.
Mixing Instructions:
Pre‑mix epoxy base then mix at ratio by weight with hardener (Check mix ratio of Hardener). Mix well by hand or mechanical mixer. Be sure to scrape sides and bottom or transfer to another container for best mix. For best results, de‑air at 29 inches of mercury before pouring. Thick pours may be successful in multiple pours, the first being thin to allow air to flow out. Allow one hour between pours. Aluminum shot can be used to bulk up epoxy for higher thermal conductive properties. Pre-mix epoxy with hardener before adding aluminum shot. A surface coat should be applied previously to prevent metal particles from protruding on tool’s working surface.
Storage:
Store at room temperature or below 90F. Keep out of sunlight or away from heat. When handling, please refer to MSDS.
