WEICON S 500 HT is a ready-to-use, very low viscosity, colourless impregnating agent which, due to its capillary effect, penetrates into pores and seals them permanently elastic. It has a high thermal resistance up to 500 °C, a very high resistance to aggressive chemicals and gives a high dielectric strength. It is suitable as a sealant for thermal spray coatings. For optimum corrosion protection results and chemical resistance WEICON S 500 HT must be annealed at 220 °C for 2 hours. The impregnation agent contains solvents.
