Momentive RTV5818-300ML Neutral Cure Single Component Silicone Adhesive Sealant Paste, Clear, 300ml Cartridge

Because it utilizes a moisture cure system, RTV5818 should not be used in thicknesses greater than 6mm (1/4 in). Where section depths exceed 6mm (1/4 in.) we recommend using Momentive Performance Materials’ one-component addition cure or two-component silicone rubber compounds.
