Redispersible Polymer Powder
RDP & VAE
RDP is a kind of powder binder made by spray drying special emulsion(high polymer). Kemox RDP is green environmental protection,building energy saving, high quality and multi-purpose powder building materials.
Kemox redispersible polymer powder (RDP) can rapidly disperse to form emulsion after contact with water and has the same properties as the initial emulsion, i.e., it can form a film after water evaporates, and this film has high elasticity, high weather resistance and high adhesion to various substrates. The addition of Kemox RDP enhances the wetting and water retention properties of the mortar.
Functions & Specifications
Improved adhesion
Improves the adhesion of building materials to substrates, reduces the risk of delamination, and increases the durability of products.
Increased flexibility
Improves the flexibility of building materials and makes them less likely to crack or break.
Improved workability
Improves the workability of building materials, making them easier to mix, apply and finish.
Improves water resistance
Improves the water resistance of building materials, increasing their durability and service life.
Improves setting time
Controlling the setting time of construction materials enables more efficient use of time.
Improves durability
Improving the durability of building materials and improving their resistance to environmental stress.

RDP & VAE Asked Questions
RDP offers several advantages over other binders and adhesives, including improved water resistance, adhesion, and flexibility, as well as ease of use and compatibility with other additives.
Yes, RDP can be used in dry-mix formulations such as tile adhesives and grouts, where it can provide improved adhesion and water resistance.
Common quality control tests for RDP include particle size analysis, bulk density measurement, and ash content determination.
RDP should be stored in a cool, dry place away from direct sunlight and sources of heat. It should also be handled with care to avoid exposure to dust and other particulates, as well as potential hazards such as fire and explosion.
Yes, RDP can be used in exterior applications such as EIFS (Exterior Insulation and Finish Systems) and stucco to improve the water resistance and durability of the material.
The dosage of RDP can vary depending on the specific application and formulation, but typically ranges from 1-10% of the total weight of the formulation.
