Three Bond 1207B - RTV-Silikon-Flüssigdichtung - 17 kg Eimer

Three Bond 1207B – Overview of RTV silicone liquid gasket

The Three Bond 1207B is an RTV silicone liquid gasket in black, packaged in a 17 kg bucket. As a sealant, it provides reliable sealing in engine and cooling circuits – even with vibrating components.

It stands out for its high adhesion, immediate sealing, and excellent resistance to coolant and engine oil. The material does not shrink and remains corrosion-resistant, even at high operating temperatures.

Composition & Properties

The RTV silicone is provided as a liquid gasket and is available in black. The main component provides excellent resistance to oil and coolants, while the material remains flexible to accommodate movements at sealing surfaces.

Fast-curing and vibration-resistant

Thanks to fast surface drying and good flexibility, the sealant is suitable for dynamic components. The elongation of 400% and tensile strength of 2 MPa enable reliable sealing under vibration and temperature changes.

Processing & Guidelines

• Thoroughly clean and degrease the surfaces.
• Apply evenly over the surface, distribute evenly, and avoid air bubbles.
• Note the surface drying time of approximately 8 minutes; room temperature is sufficient.
• Ventilate the seal joint during curing to achieve full strength.
