General Characteristics:

Chemical Name:
Sodium Gluconate
Molecular Weight:


Gluconates are important industrial chemicals because they employ the principles of sequestration and chelation under unique circumstances. While other compounds share these properties, gluconate is a superior sequestrant and remains stable even in high alkalinity and extremes of temperature. S-45 is uniquely suited to the concrete admixture industry.

Standard Packaging & Availability:

PMP S-45 is packaged in 55 gallon, plastic drums and 2500 lb totes. This product is also available in bulk tank trucks and via rail.

Storage & Handling:

PMP S-45 does not crystallize even at temperatures below 32°F. However, it is recommended that storage temperature be kept at no lower than 15°F to avoid increase in viscosity. Gentle warming, with agitation, will restore solution. This product is a weak organic acid solution, so it is preferable to use stainless steel, or plastic and glass equipment when storing or handling. The use of aluminum, mild steel, and iron as equipment for materials of construction is not recommended.
