SS5268 One-component Silicone Cured-In-Place Gaskets
SS5268 is a silicone gasket that cures in place to form a sealing gasket. It features a gray color, medium viscosity, high modulus, and low elongation at break, along with rapid curing at ambient temperatures and outstanding resistance to oil. This product is typically used for sealing high-stiffness joint surfaces and is particularly well-suited for precision mating surfaces found in applications like automobiles, motors, and internal combustion engine components.
Features and benefits
- One-part adhesive/sealant
- Alkoxy cure system
- Non-sag, paste consistency
- Easy to apply
- Cures to a tough, flexible rubber
APPLICATIONS
- Oil pan
- Transformer flange
- Gearbox, gearbox
- Motors, automotive parts
- Replace traditional gaskets and improve high-temperature tightness between metal and gaskets
