High-grade adhesive and sealing compound for use with motor vehicles. Features:
Very good resistance to chemicals - suitable for use in critical areas in which the seal may temporarily be in contact with several fluids. This product shows an excellent resistance against motor and gear oils, refrigerants and anti-freeze.
Acid-free hardening system - non-corrosive and non-conductive, therefore no negative effects on electronic components or Lambda sensors.
High temperature stability - utilization in the temperature range on machinery and engines possible.
Sealant in a compressed air spray can - easy dosage without auxiliary devices. Optimum handling, which means that an even product application using the beads is possible.
Application:
Optimal adhesion is achieved on clean and dry surfaces. Old sealing materials must be removed completely from the sealing surface.
This guide helps users understand and effectively apply Würth RTV Silicone Black, a high-performance sealant ideal for automotive and industrial applications. It's designed for anyone needing a durable, temperature-resistant seal, offering excellent chemical resistance and ease of use. A key consideration is ensuring surfaces are perfectly clean for optimal adhesion.

Troubleshooting
Sealant is not adhering properly.
Ensure the surface is completely clean and dry before applying. Remove all traces of old sealant.
Sealant is taking too long to cure.
Ensure the ambient temperature and humidity are within the recommended range. Higher humidity and warmer temperatures will speed up curing.
Sealant is leaking after application.
Ensure an even bead has been applied, and all surfaces are properly sealed. Check for any gaps or imperfections in the application.
