Silicone Sealants

Having established themselves as a key material in the construction and installation sectors, silicone sealants will continue to play an important part as regards sustainable solutions in these areas. That is why they play an essential role in most key industries. Enjoying benefits such as excellent resistance to weathering, UV, heat and aging, silicone sealants are clearly superior to alternative technologies. WACKER offers an extensive, consistently high-quality portfolio ranging from raw material to finished silicone sealant, supplied in containers, drums or cartridges.

These ELASTOSIL® silicone sealants are one-part, low-modulus formulations available in a variety of crosslinking systems. Most of our ready-to-use silicone sealants are available in a variety of container sizes. What’s more, the layout design of cartridges and foil packs can be tailored to suit the specific distribution channel of your products.

Benefits:

  • User-friendly processing properties
  • Readily able to absorb movement
  • UV resistance
  • High heat resistance
  • Resistance to extremes of weather
  • Saves energy in buildings

These ELASTOSIL® silicone sealants are one-part, low-modulus formulations available in a variety of crosslinking systems and which are ideal for professional use and more challenging applications. Most of our ready-to-use silicone sealants are available in a variety of container sizes. For example, our sealants are suitable for shipment in drums and you can then fill and finish, meter or color the sealants as you see fit. What’s more, the layout design of cartridges and foil packs can be tailored to suit the specific distribution channel of your products. You will find our portfolio includes products tailored to meet specific demands, such as flame retardance, compatibility with natural stone, and food contact.

WACKER supplies a wide range of products for compounding silicone sealants. Our silicone polymers and plasticizers satisfy all basic requirements expected by sealant manufacturers. In addition, a large number of formulation additives such as crosslinkers and adhesion promoters for neutral-curing (alkoxy) formulations and acetic-curing (acetoxy) formulations are available.

WACKER has a wide range of products for compounding standard and specialty sealants. Our experts have developed select alkoxy-terminated polymers and tailored additives for the easy and stable formulation of neutral-curing silicones. This line includes a specialty polymer for formulating waterproof coatings that can be processed in a liquid state. In addition, a large number of formulation additives such as crosslinkers and adhesion promoters for neutral-curing alkoxy formulations are available. Specialty catalysts and stabilizers with specific functions such as enhancing storage stability and rheology round out the range.

Benefits:

  • Tailored additives for a variety of needs and ensuring tried-and-true quality
  • Acetoxy crosslinker for reliable sealants and specific demands
  • Select alkoxy-terminated polymers as a basis for a new formulation technology
  • Reliable and reproducible compounding process
  • Alkoxy crosslinker packages for adapting sealant properties in a simple, reliable and flexible way
  • Simple control of physical and chemical properties
  • Optimum crosslinking for greater resistance to chemicals
  • Longer storage stability for alkoxy systems

ELASTOSIL® eco sealants differ from conventional grades merely as regards the source of the raw materials used. They otherwise provide exactly the same quality as our premium line and can be processed in the usual way.

During the production of ELASTOSIL® eco, the organic constituents are offset completely as part of the biomass balance method. The fossil raw materials needed for production are replaced by biomass certified as sustainable. This makes ELASTOSIL® eco the first generation of sealant to do without raw materials derived from petrochemicals.

Benefits:

  • 100% of the fossil raw materials needed for production are replaced by biomass certified as sustainable
  • A long shelf life
  • User-friendly processing properties
  • Exceptional ability to absorb movement
  • Excellent adhesion
  • UV resistance
  • High heat resistance
  • Resistance to extremes of weather
