Dow Corning 3140 RTV Silicone Sealant

Dow Corning 3140 RTV Silicone Sealant

If your aircraft didn't roll off the assembly line yesterday, you're probably starting to deal with loose or cracked seals, deteriorated wiring or other issues that need to be patched up ASAP. Thankfully, there's plenty of help in neat and tidy little tubes. Dow Corning® 3140 RTV Silicone Sealant is one way to get your plane from former glory to forward progress.

Dow Corning® 3140 RTV adheres to several surfaces as it is specially formulated to bond with reactive metals, ceramics and plastics. Adhesion is also possible on certain plastics, resins, and laminates. While not initially designed to affix well to non-reactive surfaces such as Teflon, its bonding can work well if special treatments (chemical etching; plasma treatment) are applied.

Another reason to 3140 RTV coat with confidence: it has excellent flowability and cures at room temperature. You know what that means? No need for a curing oven and the costs to run one. There's also no mixing required, either; just squeeze it out of the tube, apply and wait. It's even UL 94V-1, IPC-CC-830 and MIL-A-46146 tested so you can trust its effectiveness as it has overcome such rigorous standards. More features and specifications are awaiting your attention below.
