The Benefits of Using redispersible polymer powder

Redispersible polymer powders are free-flowing, white powders manufactured by spray-drying polymer dispersions. When added to water, these polymer powders can disintegrate and form individual polymer dispersions again, with identical properties as the original dispersion.

Redispersible polymer powders are added to mortar to increase the flexibility and cohesiveness of mortar. This forms a continuous polymer film that helps improve water retention, enhance the bond strength of mortar, and improve the workability of dry mix mortar.

RDP Production Process

The redispersible polymer powderredispersible polymer powder is a latex emulsion created by spray-drying macromolecular dispersions under particular conditions. During production, polyvinyl alcohol is added to stop the latex particles bonding together. These polymer powders are usually manufactured based on acrylic polymers, polyvinyl acetate, copolymers of vinyl acetate with vinyl versatate or with ethylene.
RDPs comprise of polymer resin, the crucial ingredient of dispersion particles and an important player for redispersible powders to function. As an additive, polymer powders act as modified resin and polymer resin.

Properties of Redispersible Polymer Powders

When water is added to the dry mix mortar, the polymer powder becomes a dispersion and forms a film upon drying. This film promotes elasticity and adhesion. Redispersible polymer powders are classified into highly elastic with low adhesion, rigid with high adhesion, and medium elastic with standard adhesion. Water is added to some powders to impart hydrophobic characteristics to the material.

• Vinyl Acetate-Ethylene Polymers (VAE) – These powders blend the flexibility of ethylene and the adhesion of vinyl acetate, leading to many economic and ecological benefits without affecting performance.
  They offer several benefits, including excellent cohesion, flexibility, good low-temperature film and variable glass transition temperature. They also show great adhesion to certain substrates like plastics and wood.
• Vinyl Chloride Copolymers and Terpolymers – These polymer powders show great water resistance, high hydrophobicity, and excellent tensile adhesion.
• Terpolymers based on VEOVA and VAcE – These polymer powders have extremely low transition temperatures. The benefits of using polymer powders based on VEOVA and VAcE include good workability, non-slump behaviour, good tensile adhesion strength, excellent crack-bridging properties, and low stickiness.

Applications

Redispersible polymer powders have numerous applications across various industries. They are widely used in:

• Construction adhesives
• Tile adhesives
• Joint mortars
• External wall putty
• Building binders
• Filling compositions like concrete repair joints, crack isolation membranes, and waterproofing membrane applications.

Redispersible polymer powders (RDPs) have become an important part of modern building materials. Its unique properties make it an ideal ingredient for a wide range of applications. From improved processability of building materials to high adhesive properties, RDP has revolutionized the field of construction.

Here are some typical applications of RDP:

1. Exterior Insulation and Finishing System (EIFS)

EIFS is a popular method of covering exterior walls with weather resistant insulation. One of the main components of EIFS is RDP. It contributes to the strength, adhesion and flexibility of EIFS, ensuring it can withstand varying weather conditions.

2. Tile Adhesive

Tile adhesives are widely used in interior and exterior tile applications. RDP is used to enhance the performance of these adhesives by increasing bond strength, flexibility and water resistance. This ensures that the tiles will stay in place even under heavy loads or changing weather conditions.

3. Self-leveling floor compound

Self-leveling floor compound is used to create a smooth, level surface on concrete floors. Adding RDP to these compounds improves the adhesion, processability and flow of the mixture. This ensures a flat, level and durable floor.

4. Mortar and plaster

Mortar and plaster are used to bond brick, stone and concrete blocks together and to create a smooth finish on walls. RDP is an important part of these blends as it improves their water resistance, adhesive properties and flexibility. This means mortars and plasters can withstand different weather conditions and remain strong over time.

5. Gypsum board joint compound

Drywall joint compound is used to fill gaps and joints between drywall. Adding RDP to these compounds improves processability, adhesion and durability. This ensures that the joint compound remains strong, crack resistant and easy to apply.

6. Waterproof membrane

Waterproofing membranes are used to prevent water from penetrating buildings. RDP has been added to these membranes to enhance their flexibility and adhesion, ensuring they can withstand varying weather conditions and remain strong over time.

7. Plastering

Plastering is the process of applying a layer of plaster to walls and ceilings. RDP is used to improve the adhesion and workability of the stucco, ensuring that it will apply smoothly and evenly.

8. Textured coating

Textured paints are used to create decorative effects on exterior walls. RDP is used to increase the bond strength and durability of these coatings, ensuring they can withstand varying weather conditions and remain attractive over time.

RDP has become an indispensable part of modern building materials due to its unique properties. Its use has revolutionized the field of construction, making it possible to manufacture high-quality materials with enhanced performance characteristics. Whether it is EIFS, tile adhesives, self-leveling floor compounds, mortars and plasters, plasterboard joint compounds, waterproofing membranes, plasters or texture coatings, RDP has proven to be a versatile and reliable ingredient.
