ABSTRACT:
This invention relates to antifreeze multi-component compositions which are combined substantially simultaneous with their application to target surfaces. More specifically, component part A is a mixture which includes some percentage of polysaccharides which contain acid functional groups and a gelatinous material while part B contains at least one polyvalent cation and a solvent. Part A components and part B components are kept separate until ready for application at which time part A and part B components are sprayed onto the intended surface and mixed together in the presence of pressurized air to produce a gel which will adhere to the surface being coated and react to form a resilient coating. Uses for the compositions of this invention include coating aircraft parts such as wings to prevent or remove icing while the plane awaits takeoff. At takeoff, the composition which may contain a release agent, will quickly sluff off the treated parts of the aircraft. Other uses for the tailored compositions of this invention include coating the inside of railroad cars and trucks used for carrying such materials as coal and mineral ores.
