A unique solution at all stages from process, use and end of life while meeting OEM performance requirements. The 2-part ambient curing silicone elastomer is designed to form a self-sealing layer on the inner surface of a tire. It provides outstanding sealing performance following puncture allowing driving long distances without loss of tire pressure. This novel material can be applied in a fast mass-producible process and effectively separated from the tire at end of life enabling efficient recycling. Dow’s innovative SILASTIC™ Self Sealing Silicone is leading the industry’s transition to a more sustainable future.
Self-sealing tire sealant
Removes the need for a spare tire reducing vehicle weight, improving range and fuel efficiency, whilst enabling more design freedom
Tires using SiLASTIC™ Self Sealing Silicone can be easily and quickly manufactured with standard equipment at room temperature
The surface of the tire does not need to be laser cleaned prior to coating application
Only a thin layer of silicone sealant is needed to achieve puncture resistance, long-term stability and airtightness
Can be separated from tires at the end of life, enabling efficient recycling of both tires and silicone in separate waste streams
