ABSTRACT:
The purpose of the invention is a coating precursor comprising a silicone resin and a mineral filler capable of chemically reacting so as to produce a solid layer on a substrate and a cohesive refractory layer after a calcination operation. The precursor may also include an additive capable of reducing its viscosity. Another purpose of the invention is a method for coating a given surface of a substrate with at least one refractory layer containing silicon in which the substrate is coated with a coating precursor according to the invention so as to form a green layer and a heat treatment is carried out to calcine the said green layer and to form a cohesive refractory layer. The invention is a means of obtaining a protective coating capable of resisting oxidising environments, liquid metal and a solid or molten salt.
