Redispersible Powder (RDP), also known as redispersible powder, is a groundbreaking additive in the construction industry. This polymer-based powder is designed to enhance the performance of cement mortars, wall putty, and various other construction materials. Its unique properties, including exceptional bonding ability and improved workability, make it an indispensable component in modern construction practices.
RDP significantly improves the adhesion of construction materials to surfaces. When mixed with water, it forms a film that penetrates the surface, creating a strong bond. This is particularly crucial in applications like tile bonding and wall putty, where durability is essential.
The inclusion of RDP in mortar and putty formulations reduces the risk of cracking. Its ability to enhance flexibility and tensile strength ensures that structures remain intact under various environmental conditions. This makes RDP an ideal choice for both interior and exterior applications.
RDP enhances the coating and spreading rate of mortars and putties, allowing for easier application and a smoother finish. This not only saves time but also ensures a more uniform surface, reducing the need for rework.

RDP is widely used in various construction applications, including:
To test the bonding ability of RDP, create a small solution and apply it to a clean tile. After drying, a VAE film should remain. If it is difficult to scrape off, the RDP is of high quality. 
Mix RDP into a solution and pour it into a glass dish. Upon drying, the film should be smooth and elastic. Stretching the film should reveal its tensile strength.
