WC-1 Ice Release Properties - Zero Degree Cone

Test

There exists a need for materials and surface coatings that can protect exposed structures and systems against unwanted ice accumulation caused by freezing precipitation and in-cloud icing. Surface coatings that reduce the level of energy required for ice removal, often referred to as "Icephobics", can be used for a variety of applications. For any particular application, the relative performance of the coating needs to be quantified.

The Zero Degree Cone Test (ZDCT) is used for comparing the effectiveness and durability of icephobics. The test allows measurement of the force necessary to push a coated pile out of the ice in which it was frozen. The test method also ensures that certain variables that can significantly affect results (ie. strain rate, temperature, ice structure, and surface cleanliness) are carefully controlled and repeatable. The change in adhesion strength over repeated testing on a sample provides a measure of a coatings durability. The test provide quantitative ice adhesion values for coating developers, commercial vendors, structural designers and engineers.
