Potassium chloride and urea.
Urea ice melt.
As the old saying goes as an ice melt chemical it s better than nothing but not by much.
The first measure of an ice melter s effectiveness is the range of temperatures in which it can provide deicing action in a reasonable time period.
Both need to be used at a slightly higher rate of application with urea melting to 15 o f and potassium chloride melting to 12 o f.
Urea is a compound with the chemical formula nh2 2co.
Or more importantly which one do we not choose.
Urea based ice melt products are likely some of the best choices.
Urea does not contain chlorides so it is less corrosive and safer for use on concrete.
It is less harmful to concrete and vegetation.
The tablets help prevent roof damage by melting through ice dams.
There are many reagents one can use to accomplish this but which one do we choose.
It melts ice down to 15 degrees fahrenheit.
A super refined form of potassium chloride has been used as a salt substitute in food but road quality.
While rock salt and urea both have considerable ice melting power the decision to use one over the other is dependent upon your personal circumstances.
Both of these products are commonly considered safe to use around vegetation as both are often added to fertilizer blends.
Set your store to see local availability add to cart.
However over application can cause damage to vegetation.
Potassium chloride will melt ice in temperatures down to 12 f and urea to 15 f.
Our experience is that urea provides as much traction from not melting as it does provide melting of snow and ice.
For the sake of our watershed this article will focus on urea.
Urea has a eutectic temperature of 12 2f and a practical working temperature of around 25f.
The practical lowest temperature limits for these materials is defined as effective within 15 20 minutes of application and is listed next to the material.
Potassium chloride and urea are common icemelters that are often perceived as safer products to use around vegetation.
The roofmelt ice melt is designed to eliminate the roofmelt ice melt is designed to eliminate the need to climb onto roofs while melt snow.
Both have environmental drawbacks as rock salt damages both flora and fauna but urea performs poorly when temperatures dip below 21 degrees fahrenheit.
Urea is a salt but it is a salt that your dog s body already produces and there aren t many reports of it irritating paws.
