OMEGA OB-300 에어 세트 고온 시멘트 (Bonding, Insulating, Sealing, 8 oz)

Color: Off white

Volume: 8 oz

Features: Lower thermal conductivity and coefficient of thermal expansion

Applications: Bonding, Insulating, Sealing

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.

Insulation Note: Volume Resistivity at 20°C: 10⁸-10⁹ ohm–cm;Volume Resistivity at 400°C: 10⁴-10⁵ ohm–cm;Volume Resistivity at 795°C: 10²-10³ ohm–cm
