Working Life:OMEGABOND 300® cures at room temperature by air drying in 18 to 24-hr, depending upon thickness and consistency; cure time can be accelerated by low temperature oven drying at 82°C (180°F); if the cement is to be exposed to elevated temperatures, cure for 18 to 24-hr at ambient temperature, then oven dry for 4-hr at 82°C (180°F) and for an additional 4-hr at 105°C (220°F), this helps to prevent spilling.
