With the rapid development of modern construction, the demand for high-performance dry mix materials continues to grow. Traditional cement-based mortars often face challenges such as poor adhesion, cracking, and low flexibility. To solve these issues, VAE RDP Powder (Redispersible Polymer Powder) has become a key additive in polymer modified mortar systems. By improving bonding strength and flexibility, VAE Powder for Dry Mix Mortar is widely used in tile adhesives, insulation systems, and repair mortars.

With the rapid development of modern construction systems, higher performance requirements are being placed on dry mix mortar, tile adhesive, and EIFS rendering systems. As a key functional additive, Redispersible Polymer Powder plays a critical role in improving bonding strength, flexibility, and durability.

As the size of the tiles increases, hollowing is more and more likely to occur after laying, and even the accident of the tiles falling off occurs. This problem has a lot to do with the flexibility of the bonding material.

In order to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar in mortar, it is usually necessary to add additives such as VAE Re-dispersible Polymer Powder. VAE copolymer rdp can give cement mortar better flexibility and resistance. Tensile bonding strength to resist and delay the occurrence of cracks in cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks the mortar. There are some pores inside, so the performance of the hardened modified mortar is greatly improved compared to that of cement mortar.

External wall insulation is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials, which are bonded on site
