Dow Corning DOWSIL™ 748 White Non-Corrosive Sealant from SkyGeek is a premium one-part, neutral-cure silicone designed for reliable sealing and bonding on interior and exterior surfaces. The high-performance sealant offers excellent adhesion to metals, plastics, ceramics, and glass, making it easy to bond to any part of the aircraft. The gentle formula will not damage the surface or cause corrosion, making it ideal for sensitive applications.

This versatile sealant resists moisture, UV radiation and extreme temperatures, ensuring long-term durability in challenging environments. Its low-odor formulation and easy application make it suitable for electronics, appliances, automotive components and general industrial use. The white, flexible sealant is sold in a 90ml tube for easy application, and the single-component formula requires no mixing or other types of manipulation before use. Once applied, it cures at room temperature to form a robust, watertight bond, delivering consistent performance in a wide range of sealing and gasketing applications.
