A Silicone-Based Ice-Phobic Coating for Aircraft

Publisher: NuSil Technology LLC
Overview:
In view of the significant problem faced by the aircraft industry in the event of ice build-up in an engine or on the leading edge of a plane, this paper presents an evaluation of the adhesion strength of ice to several different commercially available ice-phobic coatings. Issues related to the problem of ice build-up and ice control with reference to aircraft industry are detailed and an overview of the various ice-phobic materials is provided. Besides an explanation of unique properties of silicones and the process of developing ice-phobic coatings based on silicone polymers, the paper also reviews the polyorganosiloxane structure and the addition cure mechanism. A list of ice-phobic coatings that are tested for ice adhesion strength is given in the form of a table and the test results are evaluated. Graphical representations of the ice adhesion strength test results are also contained in this paper.
