LIWEI AF 1000
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
LIWEI AF 1000 is an aqueous composite dispersion that combines special properties of organic and inorganic components. The core of the dispersion particles is based on inorganic silica particles and the shell is based on acrylate copolymers. LIWEI AF 1000 is manufactured without alkyl phenol ethoxylate (APEO) containing compounds.
[Properties]
• Very low dirt pick-up
• Excellent color stability and compatibility, even with sensitive organic pigments
• Broad range of PVCs possible (mid-30s to mid-60s)
• Very good compatibility with silicone resin emulsion paints
• Higher inherent flame retardancy than standard acrylic systems
• Very good flexibility and adhesion
• Very good film-forming properties
• Produced without the use of APEOs
• Very good scrub resistance
• High block resistance

[Storage]
When the dispersion is stored in tanks, proper storage conditions must be maintained. The product 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 the product, 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.
