IOTAR 31800F high-performance sealant putty is specially designed for multi-material gap sealing. It cures at room temperature without heating equipment, making construction more efficient. The three-component silicone formula provides moderate elasticity and durable sealing after curing, compatible with various substrates including metals, ceramics and composites. It stands out for high temperature resistance, capable of resisting 1600-1800℃ high-temperature flame impact safely and stably. With moderate viscosity, it is easy to scrape and fill, meeting sealing requirements of complex structures. Flexible packaging is available upon customer’s request, with easy storage and up to 1-year shelf life. Widely used in high-temperature equipment, industrial machinery and aerospace components, it combines convenience and reliability.
