Abstract
An icephobic coating composition forms a coating layer that melts ice and snow upon contract and remains durable after several exposures to winter storms. The icephobic coating composition includes about 2.5% to about 12.5% by weight of latex polymer solids; about 30% to about 70% by weight of an inorganic halide salt; about 15% to about 50% by weight water; and about 1% to about 15% by weight of an organic co-solvent selected from glycerin, glycols, and glycol ethers. An alternative icephobic coating composition includes about 1% to about 20% by weight of a solution polymer instead of a latex polymer, and about 10% to about 40% by weight of a VOC-exempt organic solvent instead of the foregoing water and co-solvent.

An icephobic coating composition, comprising:
- about 5% to about 25% by weight of latex polymer dispersion;
- about 40% to about 60% by weight of an inorganic halide salt, the inorganic halide salt being at least partially dissolved in the icephobic coating composition;
- about 20% to about 40% by weight water inclusive of water of the latex polymer dispersion;
- and
- about 2% to about 10% by weight of an organic co-solvent selected from the group consisting of glycerin, glycols, glycol ethers and combinations thereof.
An icephobic coating composition, comprising:
