Room temperature vulcanized silicone rubber (RTV) can be cured under room temperature without heating. It's cured by adding defined amount reinforcing filler, curing agent and catalyst(or effected by the moisture in the air) to the silicone rubber whose terminal group is hydroxyl(or acetoxyl). It has good heat resistance, cold resistance and dielectric properties. It is widely used in architectural elements, vehicle, electronic, electricity, consumer electronics, aerospace, new energy and other industries.
