Abstract
Anti-fog and scratch resistant polyurethane compositions are disclosed which include an isocyanate prepolymer, a hydrophilic polyol and an isocyanate-reactive surfactant. The reaction product of the component produces enhanced properties having permanent anti-fog and scratch-resistant characteristics. These compositions may be used as coatings, films and self-supporting articles. Plastic substrates coated with these compositions may be subsequently subjected to thermoforming, such as molding and shaping, without loss of their properties.
