General
VINNAPAS® CA 5824 can be used in the precoat and secondary coatings that are applied in the production of tufted carpet backings. It can also be used in the production of tufted carpet tiles and woven carpets. VINNAPAS® CA 5824 offers high adhesion strength, and good flexibility.
Special
VINNAPAS® CA 5824 can be applied by a number of different application methods including foaming (direct coating), pan coating, saturation and spraying.
VINNAPAS® CA 5824 performs well on various fiber types including polypropylene, polyamide, cellulose, and polyester.
Processing
VINNAPAS® CA 5824 can take high filler loads with calcium carbonate or aluminium trihydrate (ATH) for compounding. Foam additives and surfactants can be added to VINNAPAS® CA 5824 to improve foamability and filler acceptance. The compatibility and efficacy should always be checked by conducting a storage test.
Polymer Dispersions
VINNAPAS® CA 5824 can be mixed with most VINNAPAS® and VINNOL® dispersions as well as with most anionic and / or nonionic aqueous polymer dispersions. VINNAPAS® CA 5824 is also compatible with many SB latex products. Here too, the compatibility of the mixture should be tested by conducting a storage test.
Defoaming Agents
Suitable defoaming agents include
1) SILOFOAM® SE9 or
2) Surfynol® DF58.
The compatibility and efficiency should be tested in each case.
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.
