VINNAPAS® 530 ND
VINNAPAS® 530 ND is a construction dispersion for primers, cement admixes and repair mortars. VINNAPAS® 530 ND is based on a vinyl acetate/ethylene copolymer. It reduces the elastic modulus and enhances adhesion
- VINNAPAS® 530 ND is an unplasticized 55% dispersion of a vinyl acetate/ethylene copolymer in water.
- VINNAPAS® 530 ND is suitable for modifying inorganic binders, such as cement, lime and gypsum, and improves their tensile adhesive strength, flexural strength, plasticity, abrasion resistance and workability.
- The dispersion can also be used as a sole binder for joint fillers, surface fillers and coatings.
Primers, cement admixes and concrete repair mortars are the most important applications for VINNAPAS® 530 ND. VINNAPAS® 530 ND increases mechanical strength and significantly improves adhesion to the substrate. Formulations based on VINNAPAS® 530 ND are elastic and resistant to weathering and provide excellent anchorage to organic and inorganic substrates. The dispersion is therefore ideal for applications that require flexibility and good adhesion.
For typical application fields of VINNAPAS® 530 ND, refer to the section "application". Please discuss additional applications with your WACKER customer representative.
VINNAPAS® 530 ND can be blended with most VINNAPAS® dispersions and many other aqueous polymer dispersions in any ratio. When blending, it is important to adjust the pH of both dispersions which are to be blended in a pH range in which both dispersions are stable. Storage tests should be carried out to check the compatibility of the mixture.
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.

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® 530 ND 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 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:
VINNAPAS® 530 ND is adequately preserved during transportation and storage if kept in the original, unopened containers. When stored in tanks, the dispersion should be modified with a preservative to prevent microbial contamination. Suitable measures should be taken to ensure that the tanks are properly clean. In storage tanks in which the product is not stirred, it is advisable to cover the surface of the dispersion with 1 - 2 cm of water, to which a preservative has been added. This will prevent skin formation and microbial contamination. In the case of storage in silos, it is important that the air drawn into the silo when the product is discharged is also kept free of germs. As a rule, all finished products manufactured from polymer dispersions also require preservation. The type and extent of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility and effectiveness of the preservatives should be checked for a given formulation. Preservative manufacturers will be able to advise you on the type and amount of conservation agent to use.
