ABSTRACT:
An elastomeric composition having high resistance to laser radiation and to thermal radiation, which consists essentially of a phenylpolysiloxane and an additive selected from the group consisting of titanium dioxide, boron nitride, and mixtures thereof, particularly titanium dioxide, in a proportion of about 10 to about 30 pats of the additive per 100 parts of the polysiloxane. When such elastomer composition is coated on an aerospace vehicle such as a missle, the composition then cured and subjected to high intensity laser radiation or thermal radiation, the composition forms a substantially white char which is effectively reflective to such radiation, thereby protecting such vehicle from the adverse effects of such radiation.
