ABSTRACT:
The invention provides a method of protecting an electronic or electric part by coating the part with a silicone rubber composition comprising an organopolysiloxane, an organohydrogenpolysiloxane, an addition reaction catalyst, and a filler. When metal oxide fine particles obtained by deflagration of metal powder dust in an oxygen-containing atmosphere are blended as the filler, the composition has sufficient purity to cover electronic and electric parts and cured products of the composition are improved in electrical properties and heat resistance, thereby protecting the electronic or electric part.
