$VINNAPAS<sup>®</sup> eco EN 428

VINNAPAS® eco EN 428 ist ein fossile Rohstoffe sparendes Produkt. Mit dem Kauf dieses Produktes werden 100 % der für die Herstellung dieses Produktes benötigten fossilen Rohstoffe durch nachhaltige zertifizierte Biomasse ersetzt. Das Ersetzen erfolgt auf Basis des REDcert² Biomassenbilanzansatzes, der durch den TÜV Nord auditiert wird.“


• VINNAPAS® eco EN 428 offers a unique balance of soft handle, high wet strength and broad formulation flexibility.
• Due to the particular soft character of the film it forms VINNAPAS® eco EN 428 is ideally suited as a binder for personal hygiene nonwovens and as a coating and finishing agent for woven and knitted goods.

Polymer Dispersions
 VINNAPAS® eco EN 428  is miscible with most anionic and/or nonionic aqueous polymer dispersions especially with the selfcrosslinking VINNAPAS® AN 214. This imparts a harder handle and increases the film strength. However, the compatibility of the mixture should be tested by carrying out storage tests.
VINNAPAS® eco EN 428 can be used in permanently water-repellent coatings based on Wacker® Si Finish CT 19E to impart handle to textile materials used for rain and sportswear, tents and camping goods etc. It is usually also possible to combine VINNAPAS® eco EN 428 with curable or fibre crosslinking synthetic resin precondensates and/or other reactive resins.
The pH value of VINNAPAS® eco EN 428 is usually sufficient for optimum crosslinking, but in exceptional cases the addition of 0.1–1.0 % diammonium phosphate can accelerate the process. VINNAPAS® eco EN 428 crosslinks at temperatures above 130°C, but 150 °C is necessary for optimum durability.

Fillers and Pigments
If, for coating applications, VINNAPAS® eco EN 428 is to be pigmented, only pH-value neutral fillers and pigments should be used since they would otherwise interfere with the crosslinking process which takes place in the acid pH range.


Defoaming Agents
Suitable defoaming agents are, for example, 1) SILFOAM® SE1662 or 2) FOAMASTER® WO 2310 and 3) AGITAN® 352. Their efficacy and compatibility in the formulation chosen should always be checked.

Thickening Agents
Thickeners should be pH-value neutral products e.g. cellulose derivatives, polyvinyl alcohol or polyurethane based.
VINNAPAS® eco EN 428 crosslinks under acidic conditions so that if an alkali thickenable acrylic acid copolymer is to be employed, the pH-value should be adjusted with ammonia. Their compatibility and efficacy need to be checked.

When the dispersion is stored in tanks, proper storage
conditions must be maintained. VINNAPAS® eco EN 428 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

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.
