- Application Details
- General : VINNAPAS® CA 5677 offers high dry strength, excellent absorbent properties and imparts medium/ firm hand. VINNAPAS® CA 5677 can be used for needle-felt carpets and in the precoat coatings that are applied in the production of tufted carpet backings.
- Special : VINNAPAS® CA 5677 can be applied by a number of different application methods including foaming (direct coating), pan coating, saturation and spraying. VINNAPAS® CA 5677 performs well on various fiber types including polypropylene, polyamide, cellulose, and polyester.
Processing- VINNAPAS® CA 5677 can take high filler loads with calcium carbonate or aluminum trihydrate (ATH) for compounding. Surfactants can also be added to VINNAPAS® CA 5677 to improve penetration of the binder into the substrate and improve absorbency of the finished product. Effective surfactant levels are 0.5% to 1.0% on dispersion solids. The compatibility and efficacy should be checked by conducting a storage stability test.
- Polymer Dispersions : VINNAPAS® CA 5677 can be mixed with most VINNAPAS® and VINNOL® dispersions as well as with most anionic and/or nonionic aqueous polymer dispersions. Here too, the compatibility of the mixture should be tested by conducting a storage test.
- Thickening Agents : We recommend alkali-swellable poly(acrylic acid) derivatives or products with neutral pH, e.g., those based on cellulose derivatives, poly(vinyl alcohol) or polyurethane. Their compatibility and efficacy should be evaluated.

Storage & Handling
- Shelf Life
- 6 Months
- Storage Information
- When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 6 months starting from the date of manufacture 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.
