Re-dispersible Polymer Powder RDP/VAE used in Putty powder for internal and external walls
Re-dispersible polymer powder (RDP) is a type of polymer that is used in a variety of construction applications, including putty powder for internal and external walls. RDP is made by spray-drying a water-based emulsion of vinyl acetate-ethylene (VAE) copolymer. The resulting powder is free-flowing and can be easily re-dispersed in water to form a stable polymer emulsion.
RDP has a number of properties that make it well-suited for use in putty powder. These properties include:
- Water retention: RDP helps to keep the water in the putty powder, which prevents it from drying out too quickly. This is important for ensuring that the putty has enough time to set properly.
- Strength: RDP helps to increase the strength of the putty powder, which makes it more resistant to cracking and breaking.
- Adhesion: RDP helps to improve the adhesion of the putty powder to the substrate, which ensures that the putty is securely bonded in place.
- Flexibility: RDP helps to make the putty powder more flexible, which makes it less likely to crack or break when the substrate moves or expands.
- Water resistance: RDP can help to improve the water resistance of the putty powder, making it less likely to delaminate.
In addition to its use in putty powder, RDP can also be used in a variety of other construction applications, such as:
- Tile adhesives: RDP can help to improve the water resistance, bond strength, flexibility, and drying time of tile adhesives.
- Grouts: RDP can help to improve the water resistance, strength, and flexibility of grouts.
- Finishing plasters: RDP can help to improve the water resistance, strength, and flexibility of finishing plasters.
- Troweling compounds: RDP can help to improve the water resistance, strength, and flexibility of trowelers compounds.
- Thin set mortars: RDP can help to improve the water resistance, strength, and flexibility of thin set mortars.
- Sealing slurries: RDP can help to improve the water resistance, strength, and flexibility of sealing slurries.
RDP is a versatile and effective polymer that can be used to improve the performance of a wide range of construction materials. If you are looking for a high-performance putty powder, then you should consider using a putty powder that contains RDP. This polymer can help to improve the putty’s water resistance, bond strength, flexibility, and drying time, all of which can contribute to a more reliable and durable installation.
