VINNAPAS® EZ 3019

VINNAPAS® EZ 3019 is a medium particle size, protective colloid stabilized dispersion of a vinyl acetate, ethylene and vinyl ester terpolymer. VINNAPAS® EZ 3019 is produced without the addition of any plasticizers or solvents. Additionally it is free from alkyl phenol ethoxylate (APEO) containing compounds.



特性

  • Excellent saponification resistance
  • Good pigment binding ability
  • Great versatility
  • Allows formulation without coalescing solvents

High saponification resistance, good pigment binding properties open a variety of applications for VINNAPAS® EZ 3019.
Due to its minimum film forming temperature of approx. +2°C VINNAPAS® EZ 3019 doesn’t need any coalescence aids for filming.
Versatility is a special strength of this binder

VINNAPAS® EZ 3019 is a suitable binder for the formulation of pigmented exterior masonry coatings. Due to its excellent saponification resistance VINNAPAS® EZ 3019 can also be used in silicate paints as the organic component. To ensure a good shelf life, the formulation must be carefully built around the binder.

Due to its minimum film forming temperature of approx. +2 °C VINNAPAS® EZ 3019 can be used for solvent-free, plasticizer-free and low-odor interior paints.

Interior synthetic-resin-bound plasters based on VINNAPAS® EZ 3019 can be formulated – similar like interior paints without any coalescing agents or any plasticizers. Therefore, these plasters produce very low odour during and after application.

VINNAPAS® EZ 3019 is also a suitable binder specifically for the formulation of silicon resin modified paints and plasters. It is common to combine VINNAPAS® EZ 3019 in such applications with masonry water repellents SILRES® BS 45 and SILRES® BS 1306 to yield high water vapor permeability combined with very low liquid water absorption.

In External Thermal Insulation Composite Systems (ETICS) VINNAPAS® EZ 3019 can be used as a binder for styrene-panel adhesive, base coat and resin bound plaster. Hence, only one binder is needed for the whole system.
VINNAPAS® EZ 3019 can also be used in cementitious styrene-panel adhesives by addition of wetting agents like 1)Emulan® OG.
The Fire Class B1 as per EN 13501-1 (which applies to ETICS) can be reached by the addition of flame retardant additives like aluminium hydroxide.

If the product is used in applications other than those mentioned, the choice, processing and use of the product is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

储存

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EZ 3019 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. 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

VINNAPAS® EZ 3019 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.
