R 745 Foam Insulation

R-745 foam insulation provides a non-wetting safety zone to stop molten aluminum should it escape the primary refractory before it reaches the steel superstructure of the metal-containing vessel.  The two-component foam expands as it sets, and flows into every available space to eliminate voids. 

• The flow characteristics of R-745 make the slurry easy to pour or pump.  Once dried, R-745 provides an extremely low density refractory barrier:  36lbs. per cubic foot. 
• Maximum use temperature is 2000°F.  R-745 applications include insulating behind brick and monolithic refractories in filter and degassing vessels as well as casting tables. 
• R-745 contains alumina, calcium aluminates cement and dispersing agents.  R-745 is supplied dry, and is mixed to form a slurry.
