WS-8032 Class B
1 of 264 products in this brandWS-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.

Applications & Uses
- Application Instructions
-
- Clean the surface of substrates with appropriated cleaning solutions per specification(s) using an OEM approved lintfree cloth to remove, dirt, grease and processing oils just before the application of sealant. Pour solvent onto cloth to avoid contamination of solvent supply. Clean in small areas at a time. Wipe immediately after application to prevent redeposition of contaminants on the surface. Repeat at least three times or more if required. Use fresh wiping cloth every time! Substrate composition and surface characteristics can greatly vary, which can affect sealant adhesion. It is recommended to determine adhesion characteristics of specific substrates prior to application of sealant to get consistency.
