Redispersible Polymer Powder| Drymix mortar additives

Redispersible polymer powder (RDP) is a type of polymer that is used as an additive in dry-mix mortars. RDP is a powder that is made by spray-drying a polymer emulsion. When RDP is added to water, it forms a stable emulsion that can be used to make mortar. RDP has a number of properties that make it a valuable additive in dry-mix mortars. These properties include:

• Water retention: RDP can help to retain water in the mortar, which can improve the workability of the mortar and reduce the amount of water that is needed.
• Adhesion: RDP can improve the adhesion of the mortar to the substrate, which can improve the strength and durability of the mortar.
• Workability: RDP can make the mortar easier to work with, which can improve the quality of the finished product.
• Durability: RDP can improve the durability of the mortar, making it more resistant to cracking and weathering.

RDP is a versatile additive that can be used in a variety of dry-mix mortars. It is particularly useful in mortars that are used for exterior applications, such as stucco and tile adhesive. RDP can also be used in mortars that are used for interior applications, such as joint fillers and patching compounds.

Here are some of the benefits of using RDP in dry-mix mortars:

• Improved water retention
• Improved adhesion
• Improved workability
• Increased durability
• Reduced cracking
• Reduced water damage
• Increased flexibility
• Increased resistance to weathering

RDP is a safe and effective additive that can be used to improve the performance of dry-mix mortars. It is a valuable tool for contractors and builders who want to produce high-quality mortars that are durable and long-lasting.

Here are some of the most common types of RDP used in dry-mix mortars:

• Vinyl acetate ethylene (VAE): VAE RDP is the most common type of RDP. It is a versatile and cost-effective option that can be used in a variety of mortars.
• Styrene butadiene acrylate (SBR): SBR RDP is a more expensive option than VAE RDP, but it offers better water retention and adhesion.
• Polyurethane (PU): PU RDP is the most expensive type of RDP, but it offers the best water retention, adhesion, and durability.

The type of RDP that is best for a particular application will depend on the specific requirements of the project. Contractors and builders should consult with a technical expert to select the right RDP for their needs.
