摘要 |
A storage stable particulate composition for effectivly melting ice at cold temperatures without causing corrosion damage to metals it contacts in its use area, comprising primarily a water soluble chloride salt of a metal exhibiting a positive valence of from 1 to 2, such as potassium or magnesium chloride; a minor portion of a water soluble phosphate salt such as monosodium phosphate; and a substantial amount of water soluble alkaline earth metal carboxylate, such as magnesium acetate, coatingly covering the chloride and phosphate salts. Other corrosion inhibitors and modifiers of physical properties may be combined with the chloride and phosphate salts. A method of preparing the coated deicer granules is provided.
