LIWEI CEF 52
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
LIWEI CEF 52 is a dispersion of a vinyl chloride, ethylene and vinyl ester terpolymer. LIWEI CEF 52 can be used as a binder for coating systems containing an opacifying pigment, such as polymer modified plasters. The special composition and manufacturing technology mean that LIWEI CEF 52 can be used to formulate very hydrophobic products.
[Properties]
• Excellent water resistance
• Very good alkaline resistance
• Very good flameresistance
• Good compatibility with cement

[Storage]
When the dispersion is stored in tanks, proper storage conditions must be maintained. LIWEI CEF 52 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. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of LIWEI CEF 52, 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 containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing. We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials,appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin). As polymer dispersions may tend to superficial film formation, skins or lumps may be formed during storage or transportation. A filtration process is thus recommended prior to utilization of the product.
