Coating preventing ice accumulation on surfaces

Abstract

Disclosed herein is a two-pack coating composition including A) a component A including Aa) one or more polysiloxanes with 4 or more isocyanate reactive groups; and Ab) one or more organic polymers, which differ from Aa) and which include a plurality of polysiloxane chains and isocyanate reactive functional groups; and B) a component B including Ba) a chemical species, which includes on average one or more free isocyanates groups and on average one or more hydrolysable silane groups and/or Bb) a chemical species including on average two or more free isocyanates groups and no hydrolysable silane groups. Also disclosed herein are a method of forming a cured coating layer on a substrate making use of the two-pack coating compositions and a method of using the two-pack coating composition for providing an icephobic coating to substrates.
