Gaskets

WACKER silicone rubbers possess excellent sealing and adhesive properties, are resistant to heat and fluids, and have excellent durability. This functional reliability helps to keep the occupants safe. Especially in the engine compartment, our silicone grades seal reliably under demanding conditions, such as high temperatures, constant vibration, and contact with fluids. Silicones are also an integral part of solid gaskets with their rugged multi-layer structure.

Benefits:

  • High heat stability
  • Very good resistance to fluids

Applications:

  • Cylinder-head gaskets
  • Impregnation of substrate materials (whether or not they contain sulfur)
  • Gasket contour can be screen printed
  • Topcoats for surface sealing

Unlike inserted gaskets, FIPGs do not require the mating surfaces to have high dimensional accuracy. In addition, the cured gasket material remains securely in place without the need for additional fixing. These two aspects allow wider part tolerances and lower the cost of parts development.

Benefits:

  • Effective bonding
  • Highly stable joint
  • Uniform stress distribution and perfect stress relaxation
  • Versatility
  • High cost-efficiency

Applications:

  • Oil-pan gaskets
  • Gearbox seals
  • Headlamp bonding
  • Sealing housings against moisture and the effects of weathering
