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.

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.

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.

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.

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.

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 markets vinyl chloride co- and terpolymers in the form of dispersions and solid resins under the VINNOL® trade name.

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.

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.
