Product Introduction
Momentive SNAPSIL™ RTV1673LV is a one-component, ready-to-use silicone adhesive sealant that cures at room temperature to form a tough, durable rubber. It releases low levels of methyl alcohol and residual ammonia during cure, making it a low-odor, non-corrosive solution suitable for aluminum and steel. Its thixotropic paste consistency allows easy application on vertical and overhead surfaces without sagging, while providing excellent mechanical strength, electrical insulation, and long-term environmental resistance.
Momentive SNAPSIL™ RTV1673LV Features
- One-component, room-temperature curing silicone adhesive
- Primerless adhesion to many substrates (not suitable for polycarbonate)
- Low odor and non-corrosive to aluminum and steel
- Low volatility for sensitive applications
- Good low-temperature flexibility
- High-temperature performance
- Excellent weatherability and chemical resistance
- Strong electrical insulation properties
- Thixotropic paste consistency for vertical and overhead use
Momentive SNAPSIL™ RTV1673LV Applications
- Gasketing applications requiring a non-sag, paste-like sealant
