Abstract
A surface which is to be contacted with another surface, e.g., a particulate material, in the presence of moisture (water) which is subject to freezing, is coated with a composition containing water and substantially water soluble components comprising (1) a polyhydroxy compound or monoalkyl ether thereof, (2) an organic nonvolatile compound having at least one hydrophilic group, (2) being different than (1), optionally a salt which functions to lower the freezing point of water, and a sufficient quantity of an organic polymer which functions to increase the viscosity and tackiness of the composition sufficient to retain the composition on non-horizontal surfaces to freeze proof the same.
