DOWSIL 7094
Harmonization Code : 8001.20 | Unwrought tin: Tin alloys
Main features
- Self-Leveling Flowable Placement
- 400% Cured Elongation
- 25-Minute Skin-Over Time
Product Description
DOWSIL 7094 Flowable Sealant flows and self-levels into gaps where a one-part, neutral-cure silicone sealant is required for sealing or bonding. The black or white viscous liquid has a typical density of 1.30 g/cm^3 and viscosity of 28,000 mPa s, allowing flow into gaps and airless-spray application. At 23 deg C and 50% relative humidity, it skins in about 25 minutes, becomes tack-free in about 50 minutes and cures inward from the exposed surface. After seven days under those conditions, the sealant has Shore A 19 hardness, 400% elongation and 1.2 MPa tensile strength.
Key features
- Flowable self-leveling rheology: Typical viscosity is 28,000 mPa s for gap filling and spray application.
- 25-minute skin-over time: Supports tooling and assembly before surface cure.
- Flexible cured seal: Typical elongation is 400% with Shore A 19 hardness.
Applications
Sealing and bonding applications requiring a low-viscosity, self-leveling silicone sealant.
