The Dow Corning DOWSIL™ RTV730 Solvent Resistant Sealant is a high-performance product designed for demanding sealing applications where solvent resistance is crucial. This sealant comes in a convenient 170 ml tube, making it easy to apply with precision. The single-component formula requires no mixing prior to application, cutting down on repair time and getting you back in the air faster. The sealant is formulated to withstand exposure to various solvents, oils and fuels, making it ideal for use in industrial and automotive settings where such substances are prevalent.
Dow Corning DOWSIL™ RTV730 Solvent Resistant Sealant cures at room temperature and forms a durable, flexible silicone rubber that maintains its integrity even under extreme temperatures and environmental conditions. Its excellent adhesion properties ensure a reliable bond to a wide range of substrates, including metals, glass and ceramics. Whether you are working on engine components, fuel systems or other critical assemblies, the Dow Corning RTV730 provides a dependable solution for preventing leaks and ensuring long-lasting performance. The silicone sealant has a crisp white color for a professional finish that looks great on exterior surfaces.
Dow Corning 730 Solvent Resistant Sealant is used primarily for bonding, sealing and caulking applications where resistance to the swelling effects of fuels, oils and solvents is needed. It can be used for assembling and/or repairing the fuel lines and tanks of cars, small engines, aircraft and rockets. Other potential applications include:
Sealing seams on various liquid storage tanks Sealing aerospace and automotive fuel lines and tanks Providing temporary patch for rubber linings exposed to corrosive conditions Sealing pipe joints on lines carrying corrosive chemicals and solvents Providing formed-in-place gaskets for sealing chemical compressors Providing formed-in-place gaskets where irregular shapes and harsh conditions reject ordinary seals Bonding or sealing components exposed to moisture, vibration, shock, certain fuels, oils and solvents for long periods of time Providing formed-in-place gaskets for sealing insulators and entrance ports on fluid-filled distribution transformers
