Protect against frost.

VINNAPAS® EZ 222 offers good wet tack and speed of set and is fast drying. It has low thickening response to plasticizers and solvents. The hydroxyethyl cellulose (HEC) stabilization, low viscosity, high solids content, and excellent mechanical stability allow this product to have excellent sprayability. VINNAPAS® EZ 222 exhibits good adhesion to polar and nonpolar surfaces. It also heat seals to paper and packaging films at lower temperatures than other dispersions. The dried film is clear, flexible, and exhibits very good water resistance. VINNAPAS® EZ 222 is manufactured without the use of any surfactants or defoamers that contain alkylphenol ethoxylates.

 

Adhesives Applications

 

VINNAPAS® EZ 222 has the ability to adhere to a wide variety of surfaces which makes it particularly well suited for many flocking, packaging and laminating applications. VINNAPAS® EZ 222 can be used in adhesives to bond films such as polyvinyl chloride, polyvinylidene chloride, cellulose acetate, polystyrene, and cellophane to porous substrates. It can also be used to bond such widely diversified substrates as leather, paper, cloth (made from natural or synthetic fibers), urethane foam and many types of coated paperboard — notably SBR-coated board and acrylic-coated boards.

 

Coatings Applications

 

VINNAPAS® EZ 222 can be used in flat to mid-sheen DIY architectural coatings applications. It provides excellent scrub resistance and the large particle size provides good flow and leveling. Furthermore, the dispersion can be used in intumescent coatings formulations.

 

Processing

 

VINNAPAS® EZ 222 is compatible with dextrin and does not coagulate in the presence of borax. It is compatible with other VINNAPAS® VAE dispersions, poly(vinyl acetate), and vinyl acrylic copolymer dispersions. VINNAPAS® EZ 222 can also accept high levels of various additives, including rubber lattices, while maintaining a workable viscosity.

 

Plasticizers and tackifying resins generally used with VAE and poly(vinyl acetate) and copolymer dispersions can be used with VINNAPAS® EZ 222. The thickening response of VINNAPAS® EZ 222 to solvents and plasticizers is low. Thickening can be accomplished using such materials as hydroxyethyl cellulose or polyacrylic acid-acrylamide copolymer resins. VINNAPAS® EZ 222 will accept high loadings of such fillers as calcium carbonate and clay without appreciably changing the viscosity.

储存

When VINNAPAS® EZ 222 is stored in tanks, proper storage conditions must be maintained. If stored in the original, unopened containers at cool (below 30 °C), but frost-free temperatures VINNAPAS® EZ 222 has a shelf life of 9 months from the date of manufacture. 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® EZ 222 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.

 

To maintain proper storage conditions appropriate measures should also be taken to ensure cleanliness of the tanks and pipes. In a storage tank in which VINNAPAS® EZ 222 is not stirred, it is advisable to contact your biocide representative/supplier. Proper procedures must be set up in order to prevent microbial attack between necessary periodic tank cleaning and sanitization. These procedures will vary, since loading and unloading practices in each storage situation will differ slightly.

 

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.

 

Additional information

 

If VINNAPAS® EZ 222 is used in applications other than those mentioned, the choice, processing and use of VINNAPAS® EZ 222 is the sole responsibility of the purchaser. All legal and other regulations must be complied with.
