SF3401 – Two-component Silicone Foam
SF3401 is a two-component, low density silicone sealant adhesive, which cures at room temperature to form a flexible and durable protective layer. It is designed to be dispensed and cured directly on parts to form an intergrated compression gasket. It is low to medium hardness product, primarily developed as a dispensed “foamed-in-place” gasket material for the automotive and industrial assembly & maintenance industries
