BLUESIL™ RTV 3428 A/B by Elkem Silicones is a two component, silicone elastomer which cures at room temperature by a polyaddition reaction. This reaction can be accelerated by heat. It is used in the production of flexible molds with excellent details reproduction, mechanical resistance and duration. This grade is also suitable for the production of thermal expansion formers for composite materials (the aeronautic industry, boat building) and molding objects in chocolate, sugar, marzipan. It offers easy processing & curing, outstanding tensile & tear strength and low linear shrinkage (when crosslinked at room temperature). The shelf life of BLUESIL™ RTV 3428 A/B is 20 months.
