_________________________________________________________________________________
Urea
Nitrogen Fertilizer
Effective to +15º F
Zero Ice
3-way mixture
Effective to below 0° F
Contains Magnesium Chloride
3-way mixture
Effective to -10° F
Contains Calcium Chloride
1. Only Ammonium Sulfate & Ammonium Nitrate will attack concrete
2. All other Ice Melts effect the freezing point of water
3. Increase in freeze/thaw cycles
4. Expansion of freezing water can exceed the strength of concrete
5. Prompt removal of slush and residual deicer will minimize damage
