Product Introduction
Momentive SILTRUST™ RTV88, part of the RTV31/RTV60/RTV88 family, is a high-temperature, two-part silicone elastomer supplied as a ready-to-use base compound with dibutyltin dilaurate (DBT) as the standard curing agent. The system cures at room temperature, forming a durable elastomer capable of long-term service from –54 °C up to 260 °C. Known for excellent release properties, reliable electrical insulation, and strong thermal stability, RTV88 is suitable for molding, encapsulation, and industrial rubber fabrication.
