VINNECO® CT 7030
VINNECO® CT 7030 is an aqueous polymer dispersion hybrid system based on a combination of a vinyl acetate - ethylene copolymer with modified starch.
Based on solids, the bio-based content of VINNECO® CT 7030 is approx. 30% measurable via 14C - isotope analysis.
The product is in the process of introduction into industrial use (Scale-up Product). Therefore the product data given are subject to change. Always consult WACKER POLYMERS about the product’s availability before using it for industrial
- Saves fossil resources through use of renewable raw materials
- Bio-based content measureable via 14C - isotope analysis
- Suitable for the formulation of low-odor and very-low-VOC (< 1 g/l) paints
The product is made without the use of alkyl phenol ethoxylate (APEO) containing compounds, organic solvents or plasticizers.
Due to its bio-content in the form of modified starch combined with a low MFFT and low levels of residual monomers, VINNECO® CT 7030 is a more environmentally friendly binder compared with binders solely based on fossil raw materials. It is especially suited as renewable-based binder for decorative coatings. These include interior paints ranging from flat to semi-gloss.
The rheological behavior, wet scrub-resistance, dispersibility and hiding power are comparable to binder systems based on fossil resources. The use of VINNECO® CT 7030 enables the production of low odor interior coatings free of intentionally added organic solvents, which provides high performance without compromises regarding environmental regulations. The bio-content of VINNECO® CT 7030 can be verified via isotope analysis and so the binder allows paint producers to formulate interior paints with measurably reduced contribution from fossil resources.

When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 6 months starting from the date of receipt if stored in the original, unopened containers at temperatures between 5 and 30 °C. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Iron or galvanized iron containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing. We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials, appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin). As polymer dispersions may tend to superficial film formation, skins or lumps may be formed during storage or transportation. A filtration process is thus recommended prior to utilization of the product.
Preservation for Transport, Storage and further Processing
The product is adequately preserved during transportation and storage if kept in the original, unopened containers. However, if it is transferred to storage tanks, the dispersion should be protected against microbial attack by adding a suitable preservative package.
Measures should also be taken to ensure cleanliness of the tanks and pipes. In unstirred tanks, a layer of preservative-containing water should be sprayed onto the surface of the dispersion to prevent the formation of unwanted skin and possible attack by microorganisms. The thickness of this water layer should be < 5 mm for low viscosity dispersions and up to 10–20 mm for high viscosity products. Proper procedures – periodic tank cleaning and sanitization – must be set up in order to prevent microbial attack. Contact your biocide representative/supplier for further plant hygiene recommendations. Measures should be taken to ensure that only clean air enters the tank when the dispersion is removed.
Finished products manufactured from polymer dispersions usually also require preservation. The type and scope of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility with other components and the efficacy of the preservative should always be tested in the respective formulation. Preservative manufacturers will be able to advise you about the type and dosage of preservative required.
