From Loctite: LOCTITE® SI 5900 is a moisture-cured, heavy bodied, silicone-based form-in-place flange sealant with excellent resistance to oil and joint movement. Its heavy bodied properties allow it to withstand on-line, low pressure tests before the product begins to cure. Typical applications include stamped sheet metal covers, and it’s suitable for gaps up to 6.35 mm (0.250") in metal, plastic, glass, and ceramic substrates. It has a skin-over time of just 15 minutes, and once cured provides a seal that won’t shrink, compress, crack or relax, even when exposed to oil or joint movements.
