WANWEI HD1500
[Introduction]
WANWEI HD1500 is a defoamed, semi-flexible redispersible polymer powder based on a copolymer of vinyl acetate and vinyl versatate.
[Why WANWEI HD1500?]
Mortars modified with WANWEI HD1500 exhibit:
• Improved workability
• Enhanced adhesion and cohesion
• Defoaming, suitable for highly dense structures
• Good hydrophobic properties
• Good and lasting water repellence
• Reduced water absorption
• Excellent water pressure impermeability
• Improved abrasion resistance
• Good compressive and flexural strength

[Applications]
WANWEI HD1500 is a raw material for building and construction industry, such as ready-mixed dry mortars. It is used as an organic binder in the formulation of:
• Cementitious waterproofing slurries (rigid, one-component)
• Tile grouts (CG1/CG2, ISO 13007)
• Tile grouts (CG1/CG2, ISO 13007) • Decorative finishes (e.g. stucco (Veneziano))
[Guidelines for Storage, Handlingand Powder Processing]
Store WANWEI redispersible polymer powder in a cool, dry place in original packaging at temperatures not exceeding 25 °C and process within six months after the date of delivery. When storing WANWEI products avoid higher stacking of the goods to minimize pressure on the product and avoid storing in contact with moisture or heat, or in containments open for an extended period, as this may result in blocking of the powder. If the product is stored for longer than six months after the date of delivery, users are advised to evaluate properties required for the intended use.
WANWEI redispersible polymer powders can be blended in all commercial mixers with other dry additives to produce finished products in powder form. Since WANWEI redispersible polymer powders exhibit thermoplastic behaviour, mixing times should be as short as possible, and significant temperature increases caused by strong shear forces should be avoided. All hydraulically and non hydraulically curing dry mixtures with WANWEI redispersible polymer powder can be easily mixed with water before application.
[Packaging and Transport]
Standard packaging: 25 kg paper sacks with polyethylene liners. Other types of packaging, such as Big Bags or delivery in silo wagons, are available on request.
