Wacker Products

WACKER has pioneered silicon chemistry in Europe. For more than 50 years, and have been carrying out intensive R&D in silicone technology, which has led to a large number of patents for process engineering and applied technology.

Today, with more than 2,000 different silicone products in the range, WACKER SILICONES is one of the world's leading silicone manufacturers.

Silicones, known chemically as polyorganosiloxanes, have a structure similar to that of organically modified quartz, with a backbone consisting of alternating silicon and oxygen atoms.

Their properties can be modified by attaching different organic groups to the backbone. Nearly all silicone products are derived from the following three types of raw materials:

  • Silicone fluids
  • Silicone rubbers
  • Silicone resins

WACKER SILICONES have almost unlimited applications because they possess outstanding properties, such as high resistance to temperature extremes, excellent water repellency, outstanding electrical insulation properties, high flexibility, excellent release properties and - not least - exceptional environmental compatibility.

In tune with tomorrow - that means attractive products, superior quality, modern logistics, excellent customer service and enormous ingenuity.



Because of their outstanding properties, silicone sealants today occupy a leading position among high-quality elastic joint sealants for building construction and civil engineering. Silicone sealants adhere well to most substrates and have excellent weathering and UV resistance. Other notable characteristics are that the mechanical properties of silicone sealants can be tailored to the application at hand and that the sealants exhibit high elasticity and good rebound resilience. Additionally, all these properties are virtually unaffected by changes in temperature.


Because of their outstanding properties, silicone sealants occupy a leading position among high-quality, elastic joint sealants. Window seals are exposed to high temperature differences, extreme weather-induced stress, and extensive parts’ movement. Seals for glazing applications are also exposed to extreme loads, so they need to have high mechanical strength and good adhesion. ELASTOSIL® silicone sealants are ideal in this application due to their outstanding weathering, aging and UV resistance, elasticity and good rebound resilience.
