RTV11 is a two-part, general-purpose silicone rubber compound designed for potting, encapsulation, gasketing, and mold-making applications. It consists of a base compound and DBT (dibutyl tin dilaurate) curing agent, providing flexibility in cure rates and work time.
RTV11 offers excellent adhesion with a primer, outstanding release properties, and high thermal stability, making it ideal for electrical insulation, high-temperature applications, and food-contact use (except for acidic foods, per FDA regulations).
✅ Room Temperature Cure – Cures without heat for easy processing.
✅ Adjustable Work Time & Cure Rates – Can be modified using different catalysts.
✅ Excellent Adhesion with Primer – Bonds well to various substrates.
✅ High Temperature Stability – Maintains properties from -54°C (-65°F) to 204°C (400°F).
✅ Outstanding Electrical Insulation – Provides high dielectric strength.
✅ FDA Compliance – Suitable for food-contact applications (excluding acidic foods).
📌 Potting & Encapsulation – Protects electrical coils, connectors, and sensitive electronics.
📌 Cast-in-Place Gaskets & Molds – Used in industrial and automotive sealing applications.
📌 Release Applications – Creates non-stick surfaces for easy removal of paints and adhesives.
