Dow Corning 3140 Silicone Conformal Coating

Make quick fixes and lasting repairs to your aircraft with the use of Dow Corning 3140 RTV silicone sealant from SkyGeek. As a one-part sealant, 3140 requires no mixing and is ready to apply. This silicone-based sealant cures at room temperature and features excellent flowability for easy application. After dispensing, the compound is able to flow, fill or self-level to create a tighter, more accurate seal. This aircraft sealant shows superb adhesion to materials such as plastics, ceramics and reactive metals. It can also be applied to certain laminates and resins. When plasma treatments or chemical etching is used, this silicone sealant can also adhere to non-reactive surfaces like Teflon.
