Binder composition and use thereof

Abstract

The present invention relates to a composition comprising a binder comprising one or more siloxane polymers, silicone resins, silicone based elastomers, and mixtures thereof, wherein said binder optionally comprises one or more cross-linker components comprising a silane and/or a siloxane containing silicon-bonded hydrolysable groups; and a hydrophilic powder and/or gel selected from one or more amorphous, porous hydrophilic silica(s),one or more hydrophilic silica aerogel (s) and mixtures thereof, said amorphous, porous hydrophilic silica and/or said hydrophilic silica aerogel having a BET surface area from 100 m2/g to 1500 m2/g or greater and a thermal conductivity from 0.004 to 0.05 W/m·K at 20° C. and atmospheric pressure. The invention also relates to the use of said composition as or in thermally or acoustically insulating materials and to coatings, products and articles made therefrom.
