Construction grade Re-dispersible Polymer Powder
Construction grade re-dispersible polymer powder (RDP) is a specific type of RDP designed for use in construction materials like mortar, concrete, render, and adhesives. It’s essentially a powdered form of a water-soluble polymer that, when mixed with water, redisperses into tiny particles, enhancing the properties of the mixture.
Compared to standard RDPs, construction grade types generally offer:
- Higher strength and adhesion: They create stronger bonds between components, improving overall structural integrity.
- Enhanced durability: They improve resistance to cracking, wear, and tear, extending the lifespan of construction materials.
- Increased water resistance: They make materials more watertight, protecting them from moisture damage and extending their usability in wet environments.
- Improved flexibility: They add a degree of flexibility, allowing materials to accommodate slight movements and reducing stress cracks.
- Better workability: They can improve the texture and handling of materials, making them easier to mix, apply, and finish.
Here are some specific applications of construction grade RDP:
- Mortar and concrete: Improves workability, adhesion, strength, and crack resistance.
- Render: Enhances flexibility, crack resistance, and water resistance.
- Tile adhesive: Increases bond strength, flexibility, and water resistance.
- Self-leveling screeds: Improves flow, adhesion, and crack resistance.
- EIFS (Exterior Insulation Finishing Systems): Enhances adhesion, flexibility, and crack resistance.
