Brands

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.

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® 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® 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.
