Redispersible polymer is a powdery copolymer dispersion commonly used in construction materials such as cement-based tile adhesives, grouts, and self-leveling compounds. These polymers are created by spray-drying a mixture of polymer emulsions, protective colloids, and additives, resulting in a dry, free-flowing powder easily re-dispersed in water.
When added to building materials, redispersible polymer powders act as binding agents, improving the final product's adhesion, flexibility, workability, and durability. They also enhance the material's water retention and other mechanical properties, allowing for better workability and a smoother finish. Redispersible polymers are particularly useful in construction applications where high mechanical stability and resistance to weathering and aging are required. They can also enhance the performance of mortars, renders, and other building materials, resulting in stronger, more flexible, and longer-lasting products.
