摘要： Silicone urethane (meth)acrylates can have at least three (meth)acrylate groups and not more urethane groups than (meth)acrylate groups. A method for preparing the silicone urethane (meth)acrylates involves reacting at least one hydroxy functional silicone (meth)acrylate with at least one isocyanate functional urethane (meth)acrylate. Compositions can contain the silicone urethane (meth)acrylates, and are useful for the production of release coatings, protective films, and protective coatings; and for the manufacturing of 3D printed objects by stereolithography.

摘要： Some variations provide a method of forming a transparent icephobic coating, comprising: obtaining a hardenable precursor comprising a first component and a plurality of inclusions containing a second component, wherein one of the first component or the second component is a low-surface-energy polymer, and the other is a hygroscopic material; applying mechanical shear and/or sonication to the hardenable precursor; disposing the hardenable precursor onto a substrate; and curing the hardenable precursor to form a transparent icephobic coating. The coating contains a hardened continuous matrix containing regions of the first component separated from regions of the second component on an average length scale of phase inhomogeneity from 10 nanometers to 10 microns, such as less than 1 micron, or less than 100 nanometers. The transparent icephobic coating may be characterized by a light transmittance of at least 50% at wavelengths from 400 nm to 800 nm, through a 100-micron coating.
