Detailed Product Description

DOWSIL™ 734 Flowable Sealant is a one-part RTV silicone elastomer designed for general-purpose industrial sealing and bonding. This self-leveling sealant is particularly effective for fine joints, cable entries, and repairs in existing equipment. It adheres well to a variety of substrates and provides excellent water-tight seals.

The acetoxy cure system ensures easy application and fast tack-free times, making it ideal for time-sensitive projects. Once cured, the sealant forms a tough, flexible rubber with excellent temperature and dielectric properties. Available in both clear and white formulations, DOWSIL™ 734 is suitable for a wide range of industries, including electronics, manufacturing, and aerospace.
