In the production of tile adhesive, redispersible polymer powder (RDP) plays a crucial role. It does not only significantly enhances the performance of tile adhesive but also effectively addresses common issues during construction, such as tile detachment, hollowing, and cracking.

Next, let's talk about the three main impacts of redispersible polymer powder (RDP) in tile adhesive.

1. Enhance adhesive force

Among various tiles, especially vitrified tiles and tiles with low water absorption, their surfaces are dense and smooth, making it difficult for traditional mortar to form effective bonding. Redispersible polymer powder (RDP), which contains high molecular polymers, can form a tough adhesive film between the tile and the substrate, significantly enhancing the bonding strength of the mortar.

Function: Enhance the bonding strength between tiles and the substrate, preventing tile detachment caused by thermal expansion and contraction or moisture exposure.

Features: Especially suitable for scenarios with high bonding requirements, such as large-sized tiles and exterior wall tiles.

2. Enhance flexibility and resistance to stress and cracking

During the use of buildings, they are subjected to stress impacts such as temperature changes and structural displacements. Traditional mortar, due to its high brittleness, is prone to cracking. The polymer film formed by redispersible polymer powder (RDP) exhibits excellent flexibility and toughness, capable of dispersing and absorbing stress, thereby significantly enhancing the crack resistance of tile adhesive.

Function: Effectively reduce the phenomena of hollowing and cracking, and enhance the overall structural stability.

Features: It is particularly effective in construction scenarios with significant stress variations, such as exterior walls, floor heating environments, and lightweight walls.

3. Improve water resistance and weather resistance to extend service life

Ceramic tile adhesive is commonly used in wet or exposed environments such as kitchens, bathrooms, and exterior walls, where high requirements for water resistance and weather resistance are imposed on the material. Redispersible polymer powder (RDP) can significantly enhance the compactness of ceramic tile adhesive after film formation, improve water impermeability, and simultaneously enhance resistance to environmental factors such as ultraviolet radiation and freeze-thaw cycles.

Function: Prevents the decrease in bonding strength caused by water absorption or aging during long-term use.

Features: It allows tile adhesive to maintain stable performance in humid environments and outdoors for a long time, extending the service life of tile paving.
