Description
Description: Loctite 5699 (Henkel part 2638164) is a high-performance, flexible RTV silicone gasket maker in gray paste form that cures at room temperature to form a tough, elastic seal. Engineered for demanding flange sealing, it is tack-free in ~10 minutes, resists cracking and migration under vibration and thermal cycling, and tolerates intermittent service temperatures from –75 °F to 625 °F while resisting oils, shop fluids, and glycol/water mixtures.
