Rdp Polymer Powder for Cement Based Wall Putty
RDP (Redispersible Polymer Powder) is a water-soluble polymer powder that is commonly used as an additive in cement-based wall putties. It is a copolymer of ethylene and vinyl acetate (EVA), which makes it highly resistant to water and moisture.
RDP is added to wall putties to improve their properties, such as:
- Workability: RDP makes wall putties easier to apply and spread, and it helps to prevent them from sagging or dripping.
- Adhesion: RDP improves the adhesion of wall putties to surfaces, making them less likely to crack or peel.
- Flexural strength: RDP increases the flexural strength of wall putties, making them more resistant to cracking and damage.
- Water resistance: RDP makes wall putties more resistant to water and moisture, making them less likely to be damaged by rain or humidity.
- Freeze-thaw resistance: RDP improves the freeze-thaw resistance of wall putties, making them less likely to be damaged by freezing and thawing.
In addition to its use in wall putties, RDP is also used in a variety of other applications, such as:
- Adhesives: RDP is used in a variety of adhesives, including tile adhesives, grout, and drywall joint compound.
- Paints and coatings: RDP is used in a variety of paints and coatings, including interior and exterior paints, waterproofing coatings, and elastomeric coatings.
- Textiles: RDP is used in a variety of textiles, including non-woven fabrics, geotextiles, and roofing membranes.
RDP is a versatile and valuable material that is used in a variety of applications. It is a key ingredient in cement-based wall putties, and it helps to improve their properties and performance.
