Sometimes insulation coatings are used in the rocket engine or body. As the requirement of such insulation coating, the coating material must have good ablation effect and the coating must be surely bonded to the metal during the heating from the surface, some phenolic resin, have a good ablation effect, However, in the case when the phenolic resin is used as a coating the process of curing is troublesome and the bonding to the metal is not so good. On the other hand, some epoxy resins have a good bonding property, but its ablation effect is not better than some phenol resins. On such a point of view, the epoxy resin which has a good bonding property was mixed with the powder of the phenolic resin, which is crushed after proper curing. Such epoxy resin with the powder of phenolic resin was coated to the thin stainless steel which was used as a test specimen. The coated surface was heated by a torch. The result of experiment shows that the coating of the epoxy resin mixed with powder of phenol resin has a good heat-insulation effect.
