RDP powder for EIFS
The function of RDP powder in EIFS
The Exterior Insulation Finishing System are multilayer exterior wall systems that prevent moisture from entering through walls. It’s applicable in commercial and residential buildings with excellent energy efficiency, greater design flexibility, and creativity. The EIFS has gained more and more popularity as a compound insulation system for exterior walls of buildings. The EIFS includes bonding mortar, anti-cracking plastering mortar, and exterior water-resistant putty. Each of the layers requires a certain amount of RDP powders to improve efficiency and maximise product performance.
WOTAI Chemical is your professional redispersible polymer powder manufacturer and supplier. With the most advanced technology to provide high-quality RDP powder. We support your projects with the most effective solutions.
WOTAI RDP powder key properties - EIFS additive
Promote powerful bond strength
RDP promote a high adhesiveness to any substrate. The adhesive strength is multiplied by 2 to 10 times compared to ordinary cement mortar. RDP has high toughness and is suitable for substrate expansion or contraction. No cracks appear when the shape changes—high resistance to freezing and thawing.
Provide excellent flexibility and workability
The anti-cracking plastering mortar of polystyrene board is modified by adding RDP and polymers. With superior performance. It has good anti-cracking performance and bonding performance.
Minimize water absorption
Waterproof layers can come in different colours. It is an environmental protection coating with high resistance to salt and alkali. Adding RDP powder to mortar can improve the cohesiveness, cohesion and tensile strength of mortar. It improves water retention and forms a film that reduces the evaporation of water.

Unlike wood, stucco, and other siding materials, exterior insulation systems rarely require painting. It has many advantages, including impact resistance, and design flexibility. Reduce water evaporation and humidity control.
Insulation boards are usually made of foamed polystyrene (EPS) and are attached to the substrate by adhesives. Glass fibre-reinforced mesh is embedded in the bottom layer. A waterproof layer coated on top of insulating material to act as a weather barrier.
