Brands

SEMICOSIL® is WACKER's brand name for its silicone rubber grades developed for use in electronics applications. Each product is customized to the requirements of a specific application, resulting in a portfolio of highly specialized grades.

POWERSIL® from WACKER is a portfolio of specialty silicones for power transmission and distribution. It also includes silicone fluids for transformers, and specialty silicone pastes. All POWERSIL® products meet the requisite product safety, quality and reliability demands imposed by the various applications, and are notable for their outstanding property profiles. POWERSIL® rubber grades confer lasting water repellency, resistance to leakage currents and erosion, and good low-temperature flexibility. This makes them ideal for harsh climates found in coastal and desert regions.

Under the brand family GENIOSIL®, WACKER offers organofunctional silanes and innovative silane modified polymers for bonding and sealing. Their most outstanding property is the fact that they combine environmental advantages with performance benefits.

GENIOSIL® WP silane-modified polymers are the key to innovative waterproofing products, whose properties are comparable to those of polyurethane-based liquid waterproofing coatings. Thanks to its particularly low viscosity, GENIOSIL® WP is easy to formulate without the addition of solvents, plasticizers or tin catalysts.

WACKER SilGel® comprises highly transparent, silicone rubber compounds that cure to form silicone gels. They stand out due to their low viscosity and strong inherent tack, often rendering a primer or adhesion promoter superfluous. All products can be fully automatically processed in mixing and metering units, and are ideal for efficient mass production. WACKER SilGel® products are addition-curing, RTV-2-silicone elastomers that cure both at room temperature and at higher temperatures.

ELASTOSIL® is an all-rounder for countless applications. Silicone rubbers consist essentially of silicone polymers and fillers. They cure at high temperature (HTV/LSR grades) or room temperature (RTV grades) with suitable reactants, forming a three-dimensional structure and transforming the uncured compound in a plastic state into an elastomeric rubber. Silicone elastomers are flexible at low temperatures and resistant to heat and aging (UV radiation and ozone). They are easy to process and have good mechanical properties that remain unchanged over a wide temperature range. They have a neutral taste and are biologically unreactive.

GENIOSIL® STP-E are silane-crosslinking organic polymers that combine properties typical of both silicones and polyurethanes. They are highly versatile yet easy and safe to use as they are isocyanate and solvent-free and  in case of the α-polymers  do not require tin-catalysts for curing.

LUMISIL® products are silicone solutions for high-performance LEDs. The LUMISIL® product range consists of high-performance silicones designed to meet the most exacting demands in the fields of LED production, secondary optics and lighting technology. LUMISIL® products all offer compelling properties: they support highly efficient, low-cost production and feature optimized flow and crosslinking behavior as well as high light resistance. LUMISIL® is supplied in various forms for processing to lenses by dispensing/jetting, transfer molding and injection molding.

GENIOSIL® XM range are monofunctional polymers that offer a wide range of adhesion and sealing options, even without the use of plasticizer. They are ideal for the formulation of soft yet highly elastic adhesives and sealants. The resultant product exhibits virtually universal, outstanding adhesion especially to many difficult, sometimes non-polar, substrates  in particular low-energy surfaces such as PVC, PS or EPDM.

GENIOSIL® XT grades expand the formulation capabilities with silane-terminated polymers. These new grades have been optimized to be low in viscosity but displaying a high number of silyl groups per unit volume. Consequently, the new polymers build up a solid, yet elastic network as they cure. The resulting adhesive layers and waterproofing membranes based on GENIOSIL® XT attain high inner strength, remain extremely elastic and exhibit outstanding tear resistance. Thus they are the products of choice for industrial applications.

GENIOSIL® XB for the first time exploit the advantages of silane crosslinking for user-friendly, environmentally compatible structural adhesive bonds. Thanks to their low viscosity, they can be easily compounded without using plasticizers or solvents. Moreover, the use of tin catalysts can now also be eliminated.
