Brands

The SILRES® brand comprises a wide range of silicones for coatings, paints and construction applications. The portfolio has been developed and continuously improved since the 1950's when the first silicone resins for building protection originated in WACKER laboratories. It features not only time-tested and innovative products, but also tailored solutions for a host of applications, climates and substrates. And it is supported by a range of extensive services available from our technical centers worldwide which provide further customization and customer-specific options.

HDK® Pyrogenic silica is a mature product that WACKER has produced for over 50 years and is used by customers worldwide with great success. Thanks to our integrated production system with statistical process control and highly efficient reactor dynamics, we produce pyrogenic silica of exceptionally purity. With HDK® you get not only great product performance, but also tailored customer service.

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.

DEHESIVE® products are tailored to applications and have a successful track record of over 30 years of use around the world as silicone release coatings for paper and film. DEHESIVE® silicones set standards in versatility, processability and economy. Thanks to their chemical structure, the organosilicon compounds found in DEHESIVE® silicones have excellent release properties towards sticky substances. Silicone-coated release liners not only adhere to labels to prevent contamination and damage during handling, they can also be peeled off smoothly without loss of adhesive strength. The unique market portfolio is the ideal choice wherever release papers are produced. The advanced technology is ideal for modern applications in the labeling, adhesive tape and food industries.

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.

ELASTOSIL® LR liquid silicone rubber products are two-part silicone rubber grades which can be injection molded on fully automated machines without the need for secondary processing. They are generally platinum-curing and vulcanize under heat and pressure. As a rule, the A component contains the platinum catalyst while the B component consists of the crosslinker. They are ideal for high-volume manufacturing and so help to keep unit costs down.

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.

GENIOPLAST® from WACKER are silicone-based additives and production aids for both standard thermoplastics and engineering plastics. GENIOPLAST® pellets and GENIOPLAST® additives for wood plastic composites (WPCs) enhance processes and products in the melt-processing industry.

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.

ELASTOSIL® R solid silicone rubber grades are peroxide-curing. They can be processed by conventional methods, such as extrusion, calendering, compression and transfer molding, or injection molding. They cure in heat and are ideal for manufacturing a variety of silicone rubber articles.

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.

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® 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.
