Low Water Absorption, Strong Adhesion
MIKUR Hydrophobic Redispersible Polymer Powder is designed for cement-based dry-mix mortars such as waterproofing mortar, exterior wall mortar and repair mortar. After mixing with water, the product redisperses and forms a polymer film in the mortar, helping reduce water absorption while improving adhesion, flexibility and workability.
Key Advantages
High Adhesion with Flexibility and Water Resistance
MIKUR Redispersible Polymer Powder (RDP) for exterior wall insulation systems is suitable for bonding and render mortars used with EPS, XPS and mineral wool insulation boards. RDP forms a polymer film in the mortar, improving adhesion to substrates and insulation boards while enhancing flexibility, crack resistance and water resistance under different climate and construction conditions.
Key Advantages
Redispersible Polymer Powder (RDP) is a commonly used polymer modifier in Tile Adhesive. Adding RDP can improve adhesion between the tile adhesive, substrate and tile, while improving mortar flexibility, water resistance and workability. It is suitable for different types of indoor and outdoor tile installation.
MIKUR offers RDP grades for different Tile Adhesive formulations and application requirements, including:
Basic Tile Adhesive · C1 · C2 · T Anti-Slip · E Extended Open Time · S1 Flexible · Waterproof Tile Adhesive · Large-Format and Porcelain Slab Tile Adhesive
Different RDP grades can be selected and adjusted according to cement, sand, fillers, other additives, construction conditions and target performance.
Key Advantages
Different RDP Grades for Different Dry-Mix Mortar Applications
Redispersible Polymer Powder (RDP) is a commonly used polymer modifier in dry-mix mortar. Depending on polymer type, flexibility, adhesion, water resistance and workability requirements, RDP can be used in Tile Adhesive, exterior wall insulation mortar, Wall Putty, Self-Leveling Mortar, Repair Mortar and other cement-based and gypsum-based materials.
MIKUR offers RDP products with different performance profiles, which can be selected according to the customer’s formulation system, construction requirements and final product performance.

Superplasticizer is a high-performance concrete admixture used to reduce water demand while maintaining the required workability. By dispersing cement particles, it can improve flowability and allow a lower water-to-binder ratio.
Depending on the product type and formulation, superplasticizers can also contribute to improved concrete strength, density and durability.
RDP is mainly used in Tile Adhesive, EIFS/ETICS, Self-Leveling Mortar, Repair Mortar, Waterproof Mortar, Wall Putty and other dry-mix mortar systems.
RDP can improve mortar adhesion, flexibility, crack resistance, water resistance, workability and durability.
RDP grade selection depends on the application, formulation, required bond strength, flexibility and water-resistance requirements. MIKUR can provide product recommendations based on the customer’s application.
A common RDP dosage is 1–5% of the dry-mix mortar formulation. The actual dosage should be adjusted according to the application and performance requirements and confirmed through formulation testing.
RDP is commonly supplied in 25 kg paper-plastic composite bags. Customized packaging, pallet loading and international export logistics can also be arranged.
Store RDP Powder in a dry, cool and well-ventilated place. Protect the product from moisture and direct sunlight to maintain product performance.
Yes. MIKUR can provide RDP samples, TDS, COA, SDS/MSDS and application/formulation support.
During mortar hardening, RDP forms a polymer film structure that improves the interface between the cement-based material and substrate and can increase tensile bond strength. The polymer film also improves mortar flexibility and impact resistance.
RDP is a powder product made by spray drying VAE (vinyl acetate-ethylene copolymer) and other polymer emulsions. Compared with liquid VAE Polymer Emulsion, VAE Redispersible Polymer Powder is easier to store and transport and is particularly suitable for dry-mix mortar formulations.
