vinnapas 400H
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
VINNAPAS 400H is a general-purpose redispersible polymer powder (RDP) for dry mix mortars, specifically developed to deliver reliable adhesion and processability. Based on a vinyl acetate-ethylene (VAE) copolymer formulation, it provides strong bonding strength and moderate flexibility, effectively enhancing mortar workability, crack resistance and long-term durability. This product is widely suitable for conventional construction mortars, serving as a versatile choice for general building applications.
• VINNAPAS 400H is a VAE-based redispersible polymer powder (RDP) and is dispersible in water.
• Mortars modified with VINNAPAS 400H exhibit improved adhesion, workability and crack resistance, with consistent mechanical properties. Key rheological properties such as water retention are essentially unaffected.
• The product is ideal for use in combination with other mortar additives to optimize performance of general-purpose dry mix systems.
• VINNAPAS 400H is a general-purpose redispersible polymer powder with stable chemical properties and no adverse effect on mortar rheology.
• VINNAPAS 400H contains a fine mineral filler as antiblocking agent. It is produced without the addition of organic solvents, plasticizers or film-forming agents.

[Storage]
During storage, protect the product from contact with moisture. Prolonged storage at temperatures above 30 °C, especially in combination with pressure, humidity or exposure to sunlight, may result in blocking. Carefully seal any open containers and store them under suitable conditions. We recommend storing the product in a warehouse that provides cool and dry conditions. Do not store the product for more than six months, starting from the date at which it was received, unless the Certificate of Analysis contains a different date, which would take precedence. If the product is stored longer than recommended, it may still be used but users are advised to verify the properties required for the intended use.
H Series
This is a special series focusing on strong water-repellent properties. Adding it significantly reduces the water absorption rate of mortar while maintaining adhesion and flexibility, making it particularly suitable for building applications requiring waterproofing.
A typical product is VINNAPAS 400 H, VINNAPAS 7031H, VINNAPAS 8031 H,VINNAPAS 8034 H,VINNAPAS 5549 H, a flexible copolymer powder that can be used in waterproof mortars, exterior wall insulation system plastering mortars, mineral decorative mortars, etc. After film formation, it imparts long-lasting water resistance to the mortar without affecting its water vapor permeability.
VINNAPAS® 8031 H is another representative water-repellent product in this series, commonly used in exterior wall mortars and waterproof putties to enhance the material's ability to resist outdoor damp environments.
