CS3330CI A1/2 from Flamemaster is a corrosion inhibitive access door sealant for integral fuel tanks and pressurized cabins, as a strippable fillet, and as a gasket for removable parts. Designed to seal access areas where easy separation of joint surfaces is required, it is resistant to aircraft fuels, lubricants, oils, water and weather and remains flexible at low temperatures. At room temperature, this two-part polysulfide cures to a flexible, resilient rubber.
