LOCTITE® SI 5900 - Standard Cartridge 10.0/case Flange Sealant

Features and Benefits

This 1-part, silicone-based gasketing product is suitable for various substrates. Good resistance to oil and joint movement.
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 1 mm (0.04") 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.
