The ideal sealant for machine and vehicle manufacturing

In the automotive and machine industries, sealants are exposed to particularly heavy stress and strain from heat, chemicals and oil. With a unique formulation, 345 Hitze- und Ölbeständig is the right choice for this challenge. Perfectly capable of withstanding temperatures of up to 250°C, the neutral-cure silicone can be used in settings where machinery and equipment are manufactured. Its reliable adhesion to different materials (even without primer) and fast-curing properties make working with 345 Hitze- und Ölbeständig extra-straightforward.

Applications

Main applications

Illustration Backrohr mit grün markierter Dichtung
Sealing ovens
The high temperatures need to be factored in when sealing an oven.

Other applications

Sealing floor joints in warehouses
Permanently elastic and fast-cure materials are needed to fill joints that are subject to heavy stress and strain.
Sealing machinery
Sealants for industrial machinery should be extra-resilient.
Manufacturing machinery and motors
To make electrical components, precision and resilient professional-grade materials are required.
Sealing engines and motors
Sealants that are oil-resistant and able to withstand high and low temperatures are suitable for sealing engine or motor housings.
