RTV511, RTV560 and RTV577 Silicone Elastomers
RTV511, RTV560 and RTV577 silicone rubber compounds are low-temperature two-part silicone elastomers. They are ready to use with a base compound and dibutyl tin dilaurate (DBT) as the standard curing agent. While DBT is generally appropriate for most applications, alternative catalysts are available to facilitate deep section cure, faster cure and automated mixing.
If adhesion to a non-silicone surface is required, RTV511, RTV560 and RTV577 must be applied over a primer.
RTV560 offers a wide useful temperature range of -115°C (-175°F) to 260°C (500°F) continuously and up to 316°C (600°F) for short periods of time. This is one of the widest useful temperature ranges of any silicone elastomer.
