VINNAPAS® EF 8120 (Scale-up Product)

VINNAPAS® EF 8120 (Scale-up Product)is an aqueous vinyl-acetate ethylene copolymer dispersion. It was developed as a performance advantaged alternative to vinyl acrylic copolymers with utility in low VOC interior and exterior architectural coatings.


Properties

  • Industry leading scrub resistance
  • Excellent touch-up properties
  • Excellent blending compatibility for broad usage
  • Excellent mechanical and storage stability
  • Low odor
  • Allows for low-VOC formulations
  • Produced without the use of alkylphenol ethoxylate (APEO) surfactants
  • Manufactured without the use of formaldehyde donors

VINNAPAS® EF 8120 (Scale-up Product) is optimally suited to flat to mid sheen interior architectural coatings, providing excellent scrub resistance, great touch-up properties, and robust stability. VINNAPAS® EF 8120 (Scale-up Product) exhibits an excellent thickener response with a number of different rheology modifier types, including hydrophobically modified cellulosics (HMHEC), hydrophobic ethoxylated urethanes (HEUR), and hydrophobic alkali-swellable emulsions (HASE).

 

Designed with environmental impact in mind, VINNAPAS® EF 8120 (Scale-up Product) is suitable for low odor, low VOC (<50g/L) formulations and is manufactured without the use of formaldehyde donors, APEOs, or PFAS.

 

VINNAPAS® EF 8120 (Scale-up Product) also has utility in exterior coatings, with excellent blending compatibility that provides the opportunity for economical formulations that don’t sacrifice on performance. It provides a good balance of film formation and dirt pick-up resistance properties, with excellent crack resistance over dimensionally unstable substrates.

 

Specific formulating tips are available upon request.

Storage

When the dispersion is stored in tanks, proper storage conditions must be maintained. If stored in the original, unopened containers at cool (below 30 °C), but frost-free temperatures the product has a shelf life of 9 months from the date of manufacture. 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 equipment and containers are not recommended because the dispersion is slightly acidic. Corrosion may result in discoloration of the dispersion or its blends when further processed. Therefore, the use of containers and equipment made of ceramics, rubberized or enameled materials, appropriately finished stainless steel, or plastic (e.g. rigid PVC, polyethylene or polyester resin) is recommended. As polymer dispersions may tend to superficial film formation, skins or lumps may form during storage or transportation. Filtration is therefore 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. To maintain proper storage conditions appropriate measures should also be taken to ensure cleanliness of the tanks and pipes. In a storage tank in which the product is not stirred, it is advisable to contact your biocide representative/supplier. Proper procedures must be set up in order to prevent microbial attack between necessary periodic tank cleaning and sanitization. These procedures will vary, since loading and unloading practices in each storage situation will differ slightly. 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.
