TremPro 644 RTV Silicone - Aluminum
Despite common mythology, silicone sealants are safe for aluminum and do have an important (but narrow) place in vintage trailer restoration. While we recommend using only polyurethanes (like TremPro 635 and 636) for most applications, silicone works better in a few applications. Here are a few examples:
1. Use as a plastic to metal adhesive (like applying the finish bead to Fan-Tastic vents and fans).
2. Use as a glass to metal adhesive (like bedding 1966 and 1967 Airstream Corning glass).
3. Use as a weatherstrip adhesive for silicone rubber weatherstrips and gaskets.
4. Use as a caulk when doing plumbing with kitchen and bath fixtures.
It is sometimes difficult to find silicone RTV in
color. To help with vintage trailer restoration, we sell quality TremPro 644 silicone RTV in aluminum color only.
TremPro 644 RTV is a one-part, acetoxy silicone sealant that cures to a flexible rubber when exposed to moisture present in the air. It has a vinegar odor when first applied. TremPro 644 RTV is specially designed for sealant joints between most non-porous materials such as glass, aluminum, metal and metal alloys.
Comes with a convenient screw-on tip.
