OMEGA OB-400 エアセット高温セメント (Coating, Embedding, Insulating, 8 oz)

Color: Tan to gray

Volume: 8 oz

Features: Higher thermal conductivity and coefficient of thermal expansion; high maximum temperature rating

Applications: Coating, Embedding, Insulating

Working Life: OMEGABOND 400® 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.

Insulation Note: Volume Resistivity at 20°C: 10⁸-10⁹ ohm–cm;Volume Resistivity at 400°C: 10⁵-10⁶ ohm–cm;Volume Resistivity at 795°C: 10³-10⁴ ohm–cm
