Renewable Chemistry
Highlights – Potassium Succinate Deicing Solutions
Improved Corrosion
Profile
Significantly better impact on materials than potassium acetate:
reduced corrosion of alloys and reduced concrete scaling
Bio-based, Zero
Carbon Footprint
Succinate deicer is made from fermentation, uses large quantities of
CO2 in production, virtually colorless solution (yellow index below 6)
Equivalent deicing
performance
Succinate formulation has been AMS 1435A certified, equal to K
acetate for BOD, ice melting, penetration and undercutting, freezing pt
Strong Patent
Protection
Several patents covering production and use of succinate salts as
deicing solutions and synergistic effect on freezing point
Competitive
Price
Potassium succinate is available at price comparable to potassium
acetate – and will be less expensive as KOH prices increase
