NOTES

A651 Highly concentrated gel Al2O3 content 11 - 13.5%; limited flow capability; dilution to approx. 10% Al2O3 produces a flowable suspension with a minimal sedimentation tendency plus a high reaction rate with HCl.


A211 - Standard quality powder


A215 - Faster reaction rate powder


A503 - Low bulk density powder


A611 - Standard low-viscosity paste


A621 - More reactive, higher viscosity paste


A651 - Highly concentrated gel, highly viscous


A661 - Most viscous Alugel available, resistant to sedimentation


A671 - Free flowing suspension, suitable for 2x or 3x strength formulations


A681 - Most highly concentrated Aluminum Hydroxide suspension available, highly stable.


Customers who use Alugel also purchase Sucralfate, an all-purpose antacid for immediate relief and long-term healing
