Redispersible polymer emulsion powder is a white powder formed by spray-drying polymer emulsions (such as vinyl acetate-co-ethylene copolymers).
Adhesion & flexibility
Product overview
Redispersible polymer emulsion powder is a white powder formed by spray-drying polymer emulsions (such as vinyl acetate-co-ethylene copolymers). When added to dry-mixed mortar, it re-disperses into an emulsion upon water contact, forming a polymer film after the mortar solidifies. This film acts like a high-strength mesh distributed throughout the mortar, miraculously enhancing the cement mortar's toughness, adhesion, and crack resistance.
Redispersible Polymer powder is a vital additive in dry-mix mortar, significantly enhancing its overall performance. The table below provides a quick overview of its key applications and core functions:
| Application Area | Main Types Of Dry Mortar Used In Applications | The Key Role of Redispersible Polymer Powder |
|---|---|---|
| Exterior wall insulation system | Insulation board bonding mortar, plastering mortar | It provides excellent bonding strength to prevent insulation panels from falling off, while enhancing the impact resistance and crack resistance of the plaster layer to ensure system durability. |
| Tile laying system | Tile adhesive joint mixture | It provides high bonding strength to prevent hollowing and detachment, good anti-slip and flexibility to prolong opening time for easy adjustment. |
| Flooring and self-leveling | Self-leveling mortar patching mortar | Improved mobility and self-smoothing; enhanced wear resistance, strength, and toughness of the final surface. |
| Wall plastering and putty application | Interior and exterior wall putty plaster mortar | It can greatly improve the flexibility and crack resistance of putty layer, enhance the adhesion with base layer, prevent peeling, and improve the hand feeling of construction. |
| Waterproofing and interface treatment | waterproof mortar 、 interfacial treatment agent | The elastic modulus of mortar is reduced, the crack resistance is improved, the pore is blocked to form a dense waterproof layer, and the bond strength of the interface between the new and old concrete is enhanced. |
Application and Dosage
External wall insulation system and the tile laying system are usually the areas with the largest amount of re-dispersible Polymer powder and the strongest dependence.
This is mainly because the mandatory requirements of the national building energy-saving policy make the external wall insulation system widely used in the new buildings, and the system has high requirements on the bonding strength and crack resistance of the mortar, so it is necessary to add enough glue powder to ensure the quality and safety of the project.
Moreover, the growing demand for high-performance tile adhesives has surged due to larger tile sizes and the increasing prevalence of complex applications like wall-mounted floor tiles, consuming significant quantities of redispersible Polymer powder.
