Momentive Siltrust RTV560 silicone rubber compound
A versatile, low-temperature, two-part silicone elastomer system ideal for a wide range of applications.
Momentive Siltrust RTV560 silicone rubber compound is a versatile, low-temperature, two-part silicone elastomer system ideal for a wide range of applications. This ready-to-use kit includes the base compound and dibutyltin dilaurate (DBT) as the standard curing agent, offering a convenient and efficient solution for various bonding, sealing, and encapsulation needs. While DBT is suitable for most applications, alternative catalysts are available (sold separately) to tailor cure speed and depth for specific requirements, such as deep section curing or automated mixing processes. The RTV560 excels in its ability to maintain elastomeric properties over an exceptionally wide temperature range, from -115 C (-175 F) to 260 C (500 F) continuously, withstanding even higher temperatures (up to 316 C or 600 F) for short durations. Its solvent-free composition ensures minimal odor and provides excellent adhesion when used with a primer, while also exhibiting impressive release properties. The work time and cure rate can be easily adjusted by modifying the amount and type of curing agent used.
