Application areas
The Easy Silicon HT 300 is especially suited for applications where high temperature resistance is required e.g. heat converters, boilers, steam piping, radiators, ovens, electrical insulation as well as for formed in place gaskets in the automotive field, e.g. overhead cam valve and timing chain covers, oil pans, water pumps, thermostat housings, transmission pans, etc.
The surface has to be clean, dry, free of dust and other contaminants. Adheres on most non-porous materials such as metals, glass, rigid plastics, ceramic, etc. Clean surfaces with Isopropanol or other solvents.
