WANWEI 224 HD
[Introduction]
WANWEI 224 HD is a multi-purpose construction dispersion for liquid and paste, cement-free binder technology,specifically suited for primers, ready-to-use tile adhesives and one-component dispersion-based water-proofing membranes. It is based on a hard copolymer of styrene and acrylate and belongs to the product class WANWEI HD which means that it provides a remarkable hydrophobic effect in addition to the excellent adhesion even under wet conditions.
[Properties]
• WANWEI 224 HD is a fine-particle dispersion of a special styrene/acrylate copolymer.
• WANWEI 224 HD has excellent pigment-binding capacity and very good adhesion to inorganic substrates.
• WANWEI 224 HD is ideal for manufacturing construction and tile adhesive paste with extremely good wet adhesion properties.
• WANWEI 224 HD is also used as a binder for roofing compounds, high-quality synthetic-resin and silicone-resin plasters, and as a primer for flooring compounds.

[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.
