WS-8032S Class B

WS-8032S Class B is ultralight density, high temperature resistant sealant. It has a temperature range from -65°F (54°C) to 250°F (121°C), including intermittent exposure up to 360°F (182°C). The sealant is designed for fillet sealing of integral fuel tanks and other aircraft fuselage sealing applications. It is a two-part manganese dioxide cured polysulfide system. The uncured product is a low sag thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature forming a resilient rubber, exhibiting outstanding sealing characteristics.
