DOWSIL Q3-1566 Heat Resistant Silicone Adhesive/Sealant

Dowsil Q3-1566 formerly Dow Corning Q3-1566 is a one-component adhesive/sealant for sealing and bonding applications that are exposed to high temperatures of +275°C. This silicone sealant is easy to apply and non-sagging making it suitable for vertical applications and for filling gaps to create a tight seal. When exposed to moisture in the air, Dowsil Q3-1566 will cure at room temperature to form a tough, flexible rubber. This adhesive remains flexible and stable from -50 to 275°C.

Applications

• Dowsil Q3-1566 can be used to seal industrial ovens and boilers, domestic cookers, ceramic hobs, cookers and other heating equipment.
