Material Notes:
RTV511, RTV560 and RTV577 silicone rubber compounds are low temperature two-part silicone elastomers. They are supplied ready to use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. DBT is suitable for most applications, however, other catalysts are available to facilitate deep section cure, faster cure and automated mixing.Mechanical and electrical properties for 0.5 wt% DBT curing agent added, cured 7 days at 25°C and 50% relative humidity.Key Performance Properties: Variable work times and cure rates by adjusting the amount and type of curing agentRoom temperature cure Composition free of solvents and solvent odorExcellent adhesion capabilities with primerExcellent release propertiesApplications: Cast-in-place heat shieldingThermal insulationLow and high-temperature bondingPotting and encapsulation of electrical assembliesGE Silicones became a part of Momentive Performance Materials in 2006.
