OMEGA OB-500 LIQUID 에어 세트 고온 시멘트 (Casting, Coating, Dipping, 8 oz)

Color: Off white

Volume: 8 oz

Features: Withstands short-tem immersion in molten metal; used as a coating on expendable thermocouple tubes

Applications: Casting, Coating, Dipping

Density, Max: Wet : 112 b/ft³ Dry : 82 b/ft³

Working Life: OMEGABOND 500® has a pot life of 1-hr after the powder and binder are mixed together; OB-500 reaches an initial air set after 4-hr at room temperature; a final set is only reached after oven baking at 55°C (130°F) for 4-hr; if the cement is to be used at temperatures above 100°C (212°F), OB-500 must under go an extended cure at 105°C (220°F) or above for 12 hours
