Abstract (en)
[origin: EP0700058A1] The protection method of porous components which are to be subject to large potential differences involves soaking the whole component in a hot bath of polymerisable fluid resin. The resin is polymerised after penetration into all the porous holes formed in the material. Before the soaking process, the fluid is heated under vacuum at a temperature at which it attains the required viscosity to penetrate in the pores of the material. The viscosity of the resin under these conditions is less than or equal to 0.5 Pa.s. The soaking process may be improved by subjecting the heated bath to pressure during the immersion.
