RDP for EIFS / ETICS Applications
China Reliable Manufacturer - EIFS Additives Solutions
EIFS and ETICS mortar systems are exposed to thermal movement, temperature changes and long-term weather conditions. Selecting the right redispersible polymer powder (RDP) is essential for controlling adhesion strength, flexibility and crack resistance.
Accurate™ RDP provides different polymer modification options for insulation adhesive mortar, base coats and reinforced rendering systems, helping manufacturers balance strength, flexibility and durability.
Accurate™ RDP Grades for EIFS / ETICS Applications
The suitable RDP grade depends on insulation material, mortar formulation, climate conditions and required mechanical performance.
| Performance Type | Recommended Grades | Typical Application Focus |
| Rigid RDP | 5011N / 4012N / 7118E | High adhesion and strength requirements |
| Semi-flexible RDP | 4025N / 5026 / 7620E | Balanced strength and flexibility |
| Flexible RDP | 4040N / 5045N / 8035H | Thermal movement and crack resistance |
RDP Applications in EIFS / ETICS Systems
EIFS / ETICS systems typically include several mortar layers, and each layer has different requirements for adhesion, flexibility and durability. Accurate™ RDP grades can be selected according to the mechanical performance requirements of each formulation.

FAQ
RDP is selected according to required flexibility, adhesion and durability. Rigid, semi-flexible and flexible grades are available for different EIFS formulations.
The suitable grade depends on insulation material, mortar formulation and required bonding performance. Semi-flexible grades are commonly considered for balanced performance.
Flexible RDP helps improve mortar flexibility and stress accommodation, which can reduce cracking risk caused by thermal movement.
The selection depends on whether the formulation prioritizes mechanical strength, flexibility or a balance between both properties.
