Safety & Health
- Safety
LEECAST 20-73 Part B is a super cooled liquid and may crystallize. Store at 75–95oF. If crystallization occurs, heat to 120oF in a vented oven. Do not overheat. Avoid skin contact and do not inhale vapors. Always use in a well-ventilated area.
Storage & Handling
- Handling and Mixing
LEECAST 20-73 may be mixed and poured at room temperature without de-airing. Air bubbles mixed into the system will rise out of the liquid before gellation. A typical cure cycle is overnight at 25oC plus 2 hours at 80oC or 72 hours at 25oC.
- Shelf life
12 months
