General
VINNAPAS® EN 1033 can be applied by spray, impregnation or foam. Temperatures above 150°C are necessary to achieve proper crosslinking.
Processing
Polymer Dispersions
VINNAPAS® EN 1033 can be mixed with most of the VINNAPAS® dispersions and with many other aqueous polymer dispersions. However, the compatibility of the mixture should be tested by undertaking a storage test.
Defoaming Agents
Suitable defoaming agents include:
- SILFOAM® SE1662
- FOAMASTER® WO 2310
- Agitan® 352
- SURFYNOL® DF58
Their compatibility and efficiency in the formulation chosen should always be tested.

Thickening Agents
We recommend, in particular, products with a neutral pH, e.g. those based on cellulose derivatives, polyvinyl alcohol or polyurethane, like e.g. 5)ACRYSOL® RM8. Should alcali-swellable polyacrylic acid derivatives be used those need to be chosen that are effective with ammonia, in order not to interfere with the acid catalyzed cross-linking of VINNAPAS® EN 1033. Typical alkali-swellable thickening agents are, for example
- ROHAGIT® SD15
- ACRYSOL® ASE60
- RHEOLATE® 420
- VISCALEX® HV30
The efficacy and compatibility of the formulation chosen should always be checked.

- Storage Information
- When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EN 1033 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 EN 1033 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.
