What is SILASTIC™ SST 8860 Self Sealing Silicone?
A two-part, ambient curing elastomer engineered to meet OEM performance requirements across the full tire lifecycle. It forms a durable self-sealing layer on the inner tire surface, delivering reliable puncture sealing and extended drive capability without loss of air pressure. Designed for fast, mass production application, the material offers easy processing, long working time, and stable performance across temperatures. At end of life, it can be effectively separated from the tire, enabling efficient recycling and supporting a more sustainable future.
Uses
- Self-sealing tire technology for puncture protection and air retention
- Suitable for a wide range of tire types, including passenger car, light truck, off road, two-wheeler, e bike, scooter, and bicycle tires
Benefits
- Eliminates the need for a spare tire, reducing vehicle weight while improving range, fuel efficiency, and design flexibility
- Enables fast, room temperature tire manufacturing using standard production equipment
- Removes the need for laser cleaning of the tire surface prior to application
- Requires only a thin silicone layer to deliver effective puncture sealing, long term stability, and airtight performance
- Can be cleanly separated from the tire at end of life, enabling efficient recycling of both tire and silicone materials
