Waterproof Redispersible polymer powder
Redispersible polymer powder is a free-flowing white powder formed by spray-drying EVA emulsion. It readily re-emulsifies and disperses in water to form a stable emulsion. In addition to possessing the superior properties of the original EVA emulsion, its free-flowing powder form offers exceptional convenience and reliability during handling and storage.
Key Features and Performance
Waterproof RDP focuses on enhancing the hydrophobicity and water resistance of building materials, effectively preventing moisture penetration and erosion while delaying structural aging. Suitable for waterproof mortar, tile adhesives, joint sealants, and exterior coatings, it ensures building durability in humid and rainy environments.
- Superior Hydrophobicity
Imparts hydrophobic properties to materials, effectively preventing moisture ingress into substrates and reducing damage.
- Strong Water Resistance
Maintains long-term waterproofing performance, remaining effective even in high humidity and standing water conditions.
- Superior Freeze-Thaw Resistance
Enhances mortar stability during freeze-thaw cycles, preventing cracking and spalling.
- Excellent Compatibility
Suitable for various waterproofing systems, offering good compatibility with multiple formulations and additives.
Field of application
Waterproof RDP is widely used in waterproof mortar, tile adhesives, joint sealants, and exterior wall systems to effectively enhance overall waterproofing performance, ensuring building stability and durability in humid and hot environments.
- Waterproof Mortar
Enhances mortar’s water repellency and impermeability, suitable for basement, bathroom, and roof applications.
- Tile Adhesive
Enhances the waterproofing properties of tile adhesive to prevent moisture penetration that causes hollow spots and tile detachment.
- Primer
Enhances adhesion between the substrate and waterproofing layer, ensuring the stability of the entire waterproofing system.
- Exterior Wall System
Enhances the waterproofing performance of exterior wall coatings, delaying aging and rain erosion.
