ELASTOSIL® M silicone rubber has been the ideal solution for the production of molds that are highly elastic and have excellent release properties and optimum durability. These invaluable processing properties make ELASTOSIL® M indispensable, to both industrial and artisan mold makers.

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.

VINNAPAS® is WACKER’s brand name for a versatile range of polymer-based dispersions, powders and resins that are used to improve the properties and performance of products in a wide range of industries. The portfolio has been continuously improved and optimized since the 1950s. Thus, VINNAPAS® products set the standard and are leading in many applications.

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.

The VINNAPAS® eco product line stands for polymer dispersions, dispersible polymer powders and solid resins derived from renewable raw materials via the biomass balance approach. VINNAPAS® eco grades are chemically identical to the corresponding basic VINNAPAS® products. VINNAPAS® eco dispersions, dispersible polymer powders and solid resins are manufactured using the biomass balance approach. This means that fossil raw materials are entirely replaced in the supply chain by renewable raw materials that are certified as sustainable. WACKER uses bio-based acetic acid that is a byproduct of the wood-processing industry and is certified as sustainable by PEFC® (Program for the Endorsement of Forest Certification). The bio-based acetic acid is introduced at the beginning of the production cycle. The biomass balance approach mathematically determines the percentage of dispersions, dispersible polymer powders and solid resins made from renewable (non-fossil) raw materials. VINNAPAS® eco grades are certified to the REDcert2 standard and audited by TÜV NORD, an independent German technical inspectorate.

The SILPURAN® product range comprises HTV solid and liquid silicone rubber (LSR), and room-temperature-vulcanizing grades (RTV-1 and RTV-2). These high-end silicone rubber grades meet the stringent demands of the health-care industry. All products have passed selected ISO 10993 and USP Class VI tests, and so also meet the high safety standards imposed by the health-care industry. The outstanding levels of purity needed for fulfilling the medical requirements of today and tomorrow are ensured by the WACKER CLEAN OPERATIONS program.

WACKER’s PRIMIS® brand covers specialty high-value dispersions based on high-performance acrylate copolymers, as well as a range of high-value additives. PRIMIS® enables customers to develop products with unique properties that are otherwise difficult to achieve.

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.

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.

The VINNEVA® brand comprises a range of polymer-based dispersions for the modification of bitumen emulsions. The dispersions are usually post-added to the bitumen emulsions.

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.

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.

ETONIS® is WACKER’s brand for polymer-based concrete admixtures. Targeted for the concrete industry which values effectiveness and sustainability, ETONIS® yields a technology advance by combining outstanding durability and excellent adhesion properties.

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.

NEXIVA® brand comprises spray-dried polymeric binders for use as binders in architectural coatings as well as paints, adhesives, nonwovens, carpet, sealant and paper applications. The technology is suitable for manufacturing interior wall paints in either liquid or powder form. These dispersible polymer powders allow the formulation of paints without the addition of biocides and offer key advantages when it comes to storing and transporting paints.

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.
