Abstract
A silicone resin base fire retardant system having a temperature capability at least to about 450.degree. F (230.degree. C) combines intumescent characteristics with a crusting and charring capability through use of a combination of an oxide of iron and a phosphate of potassium for crusting, along with a charring material such as tripentaerythritol and a blowing agent, such as melamine, in a silicone resin base to allow for adequate expansion.
