VINNAPAS® 7550 F
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
VINNAPAS® 7550 F is a universal premium-grade redispersible polymer powder (RDP) tailored for dry mix mortars in the construction field. Based on a vinyl acetate-ethylene (VAE) copolymer formulation, it features strong filler loading capacity, effectively improving mortar workability, stability and durability. After film formation, it delivers excellent bonding strength – not only suitable for conventional dry mix mortars but also capable of enhancing the adhesion of coatings and films. This product is particularly practical in integrated construction scenarios of interior and exterior wall coatings and mortars.
• VINNAPAS® 7550 F is a VAE-based redispersible polymer powder (RDP) and is dispersible in water.
• Mortars modified with this product exhibit strong filler loading capacity, improved cohesion, stability and long-term durability, with optimized workability.
• It enhances the adhesion of coatings and films to substrates, facilitating integrated construction of mortars and coatings.
• The product has good compatibility with various fillers and coating components, supporting flexible formulation adjustment.
• VINNAPAS® 7550 F contains a fine mineral filler as antiblocking agent. It is produced without the addition of organic solvents, plasticizers or film-forming agents.
