ThreeBond 1217G One-part, room-temperature-curing, silicone sealant for FIPG(high extension type)

ThreeBond 1217G is a one-part, room-temperature-curing silicone sealant for FIPG. It is a high-elongation type.
It has excellent resistance to engine-oil, and is suitable for sealing of high-grade oil. It also has excellent initial resistance to pressure, and withstands vibration well.

·	Has excellent resistance to engine oils such as SJ oil.
·	Has excellent initial resistance to pressure.
·	Has high elongation and withstands vibration well.
·	Has excellent resistance to heat and cold. Retains the elasticity of rubber in a wide range of temperatures, from -60 to 200°C or even, briefly, to 250°C.
·	Is a deoxime type and does not sag.

·	Surface sealing of oil pans of automobile engines, chain cases, etc.
