Product Introduction
Momentive RTV60 is a two-component high-temperature silicone rubber composed of a base compound and DBT (dibutyltin dilaurate) curing agent. With a unique medium viscosity (47,000 cps) balancing flowability and anti-sag properties, it cures completely at room temperature within 24 hours without heating equipment. Solvent-free and odorless, it forms a resilient elastomer maintaining mechanical integrity across extreme temperatures (-54°C to 260°C).
Advanced Technical Properties
RTV60 delivers exceptional mechanical and electrical stability post-cure:
- 57 Shore A hardness provides optimal flexibility without brittleness
- 990 psi tensile strength and 40 lb/in tear strength exceed industrial sealing standards
- 4.4×10¹⁴ ohm·cm volume resistivity guarantees high-voltage insulation reliability
- 0.31 W/m·K thermal conductivity balances insulation and heat dissipation
Cure speed is adjustable via DBT concentration (0.1%-0.5%), while vacuum degassing eliminates bubbles for defect-free deep-section curing.
Application Scenarios
RTV60 is widely used in high-temperature and electrical protection scenarios:
- EV Motor Potting
- Tesla motor controller sealing (Source: Electrek 2022)
- Withstands 260℃ powertrain peaks, compliant with ISO 16750
- Aircraft Engine Gaskets
- Lockheed Martin F-35 APU seals (Source: Aviation Week)
- Resists jet fuel corrosion, meets MIL-R-25988
- 3D Printing Molds
- Stratasys J850 PolyJet tooling (Source: Stratasys Whitepaper)
- Supports metal injection molding <300℃, reusable >50 cycles
