RTV577 silicone rubber compound is 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. RTV577 has the widest useful temperature (highest and lowest) of any silicone elastomer
FEATURES:
- Variable work times and cure rates by adjusting the amount and type of curing agent
- Room temperature cure
- Composition free of solvents and solvent odor
- Excellent adhesion capabilities with primer
- Excellent release properties
- Retention of elastomeric properties with the following temperature ranges:
- RTV511 at temperatures from -115°C (-175°F) up to 204°C (400°F) continuously and up to 260°C (500°F) for short periods of time
APPLICATIONS:
- Cast in place heat shielding
- Adhesion of thermal blankets
- Protective coatings and thermal insulation for sensitive components and critical equipment
- Encapsulants & potting for high heat locations
- Interior & exterior adhesives
- Flexible composite coatings
