Wurth RTV Silicone Sealer

Instructions

Optimum adhesion to dry, clean and dust-free surfaces. The old sealant must be removed in full from the surface.

Excellent resistance to chemicals

Can also be used in critical areas in which the seal comes into contact with various liquids
Outstanding resistance to engine oil and transmission oil, refrigerant and anti-freeze agent
Non-acidic hardening system

Non-corrosive, therefore has no negative impact on electronic components and on lambda probes
Sealant in compressed-air can

Easy to dispense without additional aids
The fine beads allow the product to be applied uniformly
Notice
When sealing e.g. oil pans and gearboxes it is vital that no sealant gets into the interior. For this reason we recommend to apply the sealant on a joining part surface. Join both parts and then carefully press by hand and lightly slide against each other. Afterwards separate the parts again and then remove the sealant that has gone inside. Join the components again within a max. of 5 minutes and tighten firmly. Before commissioning, observe the hardening time (depending on the sealant thickness).

The usage instructions are recommendations based on the tests we have conducted and are based on our experience; carry out your own tests before each application. We do not assume any liability for a specific application result due to the large number of applications and storage and processing conditions. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.
