Dispersible polymer powder (DPP) is a type of polymer material that is used as a binder or adhesive in a variety of applications. It is typically made by spray drying a polymer emulsion, resulting in a fine powder that can be easily mixed with water to form a stable dispersion.
Dispersible polymer powders are commonly used as a binder in construction materials such as cement-based tile adhesives, mortars, and screeds. They are also used in the production of coatings, paints, and other products where improved adhesion and durability are required.
The advantage of using dispersible polymer powder is that it can improve the adhesion and cohesion of the final product, making it stronger and more resistant to cracks, water, and other environmental factors. It can also improve workability and reduce the shrinkage of the final product.
Dispersible polymer powders can be made from a variety of polymers, including vinyl acetate-based polymers (such as polyvinyl acetate or PVAc or VAE), acrylic-based polymers, and styrene-butadiene-based polymers. The specific type of polymer used will depend on the desired properties and application of the final product.
Overall, dispersible polymer powder is a versatile material that can improve the performance and durability of a wide range of products.
