WEICON Black-Seal

Special Silicone / Adhesive & Sealant

Black-Seal is especially suited for the use in machine construction and engineering as well as for engine and car manufacturing.

It provides excellent adhesion on aluminium, steel, wood, glass, ceramics and many other materials.

Due to its outstanding characteristics like extraordinary pressure absorption and controlled swelling properties as well as the perfect formed-in-place gasketing capacity, Black-Seal offers a variety of leak-proof applications on:

  • engines and water pumps
  • gears and axles
  • oil sumps etc.

even under tough operating conditions.

In addition, Black-Seal distinguishes itself by its high resistance to greases, oils and other liquids used in machine construction and car manufacturing.
