Three Bond 1207B - RTV-Silikon-Flüssigdichtung - 100 g Tube

Three Bond 1207B - RTV Silicone Liquid Gasket Overview

The Three Bond 1207B is an RTV silicone liquid gasket that is characterized by high adhesion, fast curing, and excellent resistance to coolant and engine oil. The gasket is based on an RTV silicone system and is available in black. It is especially suitable for applications requiring a robust seal under vibration.

Key performance data include viscosity at 25 °C: 100 Pa·s, density at 25 °C: 1.01 g/cm³, and a temperature range of -60 °C to 200 °C (short-term up to 250 °C). Surface drying occurs in about 8 minutes, elongation reaches 400%, and tensile strength is 2 MPa. The Shore D hardness is 30. Shelf life is 12 months from manufacture.

Sales units include 100 g tubes, 333 ml cartridges and 17 kg pails.

Suitable for Liquid Gaskets

Applications in automotive and machinery sectors

Because of its high adhesion and resistance to coolant and engine oil, the product is ideal as a liquid gasket in areas where reliable sealing is required under varying temperatures and operating loads. The black coloration facilitates visual inspection of the seal during assembly.
