WANWEI EP 8010
[Introduction]
WANWEI EP 8010 is an aqueous polymer dispersion based on the monomers vinyl acetate and ethylene. It is produced without the use of plasticizers.
[Properties]
• High adhesion on difficult to bond surfaces like e.g. Polystyrene and Polyester, UV lacquers and others.
• Excellent balance between the high adhesion and heat resistance of the glue line.
Specific features
• Adhesion on critical surfaces
• Excellent adhesion
• Produced without APEO

[Storage]
When the dispersion is stored in tanks, proper storage conditions must be maintained. WANWEI EP 8010 has 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. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of WANWEI EP 8010, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. 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 resins) is recommended. As polymer dispersion may tend to superficial film formation, skins or lumps may form during storage or transportation.Filtration is therefore recommended to utilization prior of the product.
