This specification covers a one-part fluorosilicone (FVMQ) adhesive/sealant, supplied in cartridges, suitable for extrusion and curing to an elastomeric material upon exposure to air. It also covers a compatible primer. This adhesive/sealant has been used typically for bonding cured fluorosilicone rubber and for sealing applications requiring resistance to fuels, oils, or solvents from -65 to +400 degrees F (-54 to +204 degrees C). but usage is not limited to such applications. This product should not be used for fay surface sealing or similar applications where exposure to air cannot be maintained. This product should not be used in thicknesses greater than 0.25 inch (6.4 mm), particularly in applications involving encapsulation.
