Abstract: Ceramic black materials for use as, or in, colorants, inks, pigments, dyes, additives and formulations utilizing these black materials. Black ceramics having silicon, oxygen and carbon, and methods of making these ceramics; formulations utilizing these black ceramics; and devices, structures and apparatus that have or utilize these formulations. Plastics, paints, inks, coatings, formulations, liquids and adhesives containing ceramic black materials, preferably polymer derived black ceramic materials, and in particular polysilocarb polymer derived ceramic materials.

Abstract: Polyurethane compositions including the reaction product of a polyurethane prepolymer component including (a) at least one isocyanate-terminated polyalkadiene prepared by capping hydroxy-terminated polyalkadiene having a molecular weight from about 1500 to about 5000 grams per mol (g/mol) with isocyanate; and (b) at least one additional isocyanate-terminated polyalkadiene prepared by capping hydroxy-terminated polyalkadiene having a molecular weight from about 500 to about 1500 g/mol with isocyanate with a curative component. The compositions exhibit numerous useful properties, such as low glass transition temperature (Tg) high temperature stability, low viscosity at room and elevated temperatures, flexibility and flat dynamic mechanical properties versus temperature.
