摘要： Radar attenuating compositions comprising a low viscosity siloxane polymer, a resinous crosslinker therefor and carbonyl iron powder have improved thermal stability when exposed to temperatures as high as 450.degree. F. The particular crosslinker that is used in the compositions of this invention provides improved stability for the compositions at room temperature storage conditions and also in the cured form. The compositions can be sprayed and/or molded and cured at room temperature and/or elevated temperatures, as desired.
