VINNOL® CE 35 (USA)

VINNOL® CE 35 (USA) is an aqueous dispersion of a terpolymer of vinyl chloride, vinyl acetate and ethylene.



Eigenschaften

  • VINNOL® CE 35 (USA) is a stiff film-former and imparts excellent heat-sealability and high frequency (HF)-weldability to nonwovens & textiles substrates.
  • Because of its high chlorine content, VINNOL® CE 35 (USA) can be used in conjunction with antimony oxide, phosphorous-nitrogen compounds or other flame-retardant additives to produce flame retardant coatings.
  • It also especially suitable for making plasticizer-free heat sealable and high frequency weldable coatings on paper and cardboard.

General

VINNOL® CE 35 (USA) is especially suitable as binder for heats-sealable/ HF-weldable waddings. It sprays well and does not generate unpleasant odors during processing.

Polymer Dispersions

VINNOL® CE 35 (USA) is miscible with most anionic and/ or nonionic polymer dispersions especially with VINNOL® CEN 2752. The latter will soften hand feel.

Solvents and Plasticizers

The flame-retardant effect of VINNOL® CE 35 (USA) can be increased by adding, for example phosphorous-nitrogen compound, which also softens the polymer film and lowers the glass transition and minimum film forming temperatures.

The addition should be made at room temperature, but the mixture should then be heated at about 50 °C for 1 hour to ensure that the plasticizer diffuses completely into the resin particles.

Defoaming Agents

If necessary, VINNOL® CE 35 (USA) dispersion can be defoamed with 1) SILFOAM® SE1662, for example. The efficacy and compatibility of the formulation chosen should always be checked.

Thickening Agents

Polyurethane thickeners such as 2)ROHAGIT® SD15, 3)ACRYSOL TM RM8, 4)Rheovis® AS 1125 are recommended to use with VINNOL® CE 35 (USA). The efficacy and compatibility of the formulation chosen should always be checked.

Lagerung

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNOL® CE 35 (USA) 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

VINNOL® CE 35 (USA) is adequately  reserved during transportation and storage if kept in the  original, unopened containers. However, if it is  ransferred 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 ontamination. 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.
