VINNAPAS®
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. In line with our sustainability strategy, VINNAPAS® grades are now also available as VINNAPAS® eco grades, based on renewable resources.
Vinyl acetate-ethylene (VAE) structure
VINNAPAS® products are co- and terpolymers of various monomer units, such as VAc, S-A, A, VC-E and VAE. They are produced in our integrated ethylene production system, which reuses raw materials, byproducts and energy, ensuring seamless quality control and good eco-efficiency.
WACKER first started producing VINNAPAS® vinyl acetate-ethylene (VAE) grades in the 1960s. This technology offers huge future potential, since VAE combines technical performance with environmental benefits at an attractive cost-in-use ratio. We are now also able to produce VINNAPAS® grades using renewable resources. For more information, check out our VINNAPAS® eco brand.
VINNAPAS® polymer powders are world market leaders as high-quality binders for dry-mix mortars. Polymer dispersions have set standards as binders in many applications such as paints, adhesives or nonwovens. And VINNAPAS® solid resins support our customers in the production of composites with Class A surfaces, among others.
All VINNAPAS® grades feature extremely high binding power, often combined with high flexibility, making them ideal as adhesion promoters for a variety of substrates. Depending on the polymer composition, specific grades also transfer properties such as hydrophobicity, heat resistance or flame-retardancy.
Main Application Areas
- Construction
- Paints and coatings
- Adhesives
- Nonwovens and textiles
- Composites
We are now also able to produce VINNAPAS® grades using renewable resources. For more information, check out our VINNAPAS® eco brand.
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® (Programme 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.
Properties and Advantages
- This line comprises products where fossil raw materials have been replaced by certified, sustainable biomass. Dispersions are 60 or 100 percent biobased, while dispersible polymer powders and solid resins are 100 percent bio-based.
- The properties of VINNAPAS® eco grades are identical to those of the basic VINNAPAS® grades derived from fossil raw materials.
- On the customer front, no formulation changes are needed (drop-in replacements).
- VINNAPAS® eco dispersions, dispersible polymer powders and solid resins are produced at European sites for applications in construction materials, construction coatings, composites, adhesives, nonwovens, technical textiles and carpet backing adhesives.
