- Skin-Over in About 5-7 Minutes
- Non-Sag Acetoxy Paste
Product Description
DOWSIL Q3-1566 Heat Resistant Adhesive/Sealant is a one-part, acetoxy-cure silicone paste for high-temperature bonding and sealing. The non-sag material skins in about 5-7 minutes at room temperature and 50% relative humidity, becomes tack-free in about 18 minutes, and cures about 3 mm deep in 24 hours under the same conditions. After seven days at 23 deg C and 50% relative humidity, typical cured properties include Shore A 43 hardness, 3.6 MPa tensile strength, and 340% elongation. It remains flexible from -50 to 275 deg C, with short peaks up to 350 deg C.
Key features
- About -50 to 275 deg C Long-Term Service Range: Short-duration temperature peaks are listed up to about 350 deg C.
- About 5 to 7-Minute Skin-Over Time: This surface-cure milestone occurs during room-temperature moisture cure.
- One-Part Acetoxy Silicone: Moisture-cure adhesive/sealant is supplied for high-temperature bonding and sealing.
Applications
Ovens, cookers and heating equipment; automotive sealing involving oil or coolant exposure.
