ELASTOSIL® RT 607 A/B - Flame Retardant RTV-2 Silicone Rubber
ELASTOSIL® RT 607 A/B is a castable, addition-curing, two-component silicone rubber (RTV-2) that vulcanizes at room temperature. This high-performance platinum catalyst silicone was specifically developed for professional applications in the railway, electronics, and hydroelectric power industries.
Key Features
- Two-component system with 9:1 mixing ratio (A:B)
- Low viscosity (10,000 mPa·s mixed) for optimum workability
- Fast heat curing - 30 minutes at 150°C
- High hardness - Shore A 55 after curing
- Excellent heat stability for long lasting performance
- Flame retardant - complies with EN 45545-2:2020 for HL1, HL2 and HL3
- Platinum catalyst for reliable addition curing

Applications
- Electronics - Encapsulation of electronic components
- Railway Industry - Meets strict fire safety requirements EN 45545-2:2020
- Hydroelectric power plants - Potting for electric coils of lifting magnets
- General Encapsulation - Slotted Exit Potting for Electrical Coils
Processing
Note: Only components A and B with the same batch number may be mixed. Mix the two components thoroughly at a 9:1 weight ratio. For optimal results, vacuum encapsulation is recommended to eliminate air pockets.
Reactivity can be adjusted with Catalyst EP (increases reactivity) or Inhibitor PT 88 (extends pot life). Detailed processing instructions are available in the WACKER technical documentation.
Safety and storage
ELASTOSIL® RT 607 A/B contains no toxic or corrosive substances that require special precautions. Store according to the "Best Before" date on the product label. Consult the safety data sheet for complete information.
