KDO Redispersible polymer powder (RDP) in a reasonable formula can increase the bonding strength with a small amount of addition. KDO Redispersible polymer powder (RDP) is a spray-dried dispersion. When added to water, it forms a stable dispersion with the same properties as the original emulsion. There are certain conditions for the production of Redispersible polymer powder (RDP), which needs to be carried out under high temperature conditions.KDO Redispersible polymer powder (RDP) has strong adhesion. From the perspective of actual application, as a putty for external wall insulation and paint transition layer, its strength is not suitable. It is higher than the plastering mortar, otherwise it is prone to cracking. In the whole insulation system, the flexibility of the putty should be higher than that of the base material. In this way, the putty can better adapt to the deformation of the substrate and buffer its own deformation under the action of external environmental factors, relieve stress concentration, and reduce the possibility of cracking and peeling of the coating.

   KDO Redispersible polymer powder (RDP) is used to produce putty powder. During the production process, KDO Redispersible polymer powder (RDP) can be dispersed again and re-emulsified. The base layer continuously absorbs the free moisture in the internal voids of the mortar, and the strong alkaline environment provided by the cement. After drying, the latex particles form a water-insoluble continuous film in the mortar. This continuous film is formed by fusing the single dispersed particles in the emulsion into a homogeneous body. KDO Redispersible polymer powder (RDP) can also improve the construction performance, so that the produced putty powder and dry powder mortar can be better constructed, and the scratch resistance and flexural strength of the mortar after adding it are also improved, which can make the mortar plastic and solidity less.

      KDO Redispersible polymer powder (RDP) is a polymer emulsion that is spray-dried and can be restored to an emulsion state after adding water. Due to this characteristic, it is widely used in one-component JS waterproof coating, polystyrene board bonding mortar for building insulation, flexible surface protection mortar, polystyrene particle thermal insulation coating, tile adhesive, self-leveling flooring, dry-mixed mortar, putty, etc. The fields that need to modify the inorganic gelling materials have been widely used. KDO Redispersible polymer powder (RDP) can enhance the strength of the product. Adding KDO Redispersible polymer powder (RDP) to putty powder and mortar can increase its strength, and it is very helpful to improve the hardness. It has outstanding waterproofing performance, good bonding strength, can also increase the elasticity of the mortar and have a longer open time, and endow the mortar with excellent alkali resistance, and can improve the adhesion/adhesiveness and flexural strength of the mortar. In addition to strength, wear resistance and constructability, it has stronger flexibility in` flexible anti-cracking mortar.

       KDO Redispersible polymer powder (RDP) has strong adhesion and mechanical properties, outstanding water resistance, permeability, and excellent alkali resistance and abrasion resistance in putty powder, and can improve water retention, open time and enhanced durability. When the KDO Redispersible polymer powder (RDP) is stirred evenly in the putty powder and mixed with water, the polymer emulsion is formed when it meets water, and the cement gel is gradually formed through the initial hydration of the cement, and the liquid phase is formed by Ca(OH)2 during the hydration process. Saturated, while the latex powder is dispersed into fine polymer particles, which are deposited on the surface of the cement gel/unhydrated cement particle mixture; as the cement is further hydrated, the water in the capillary pores decreases, and the polymer particles are gradually restricted in the capillary pores, A tightly packed layer is formed on the cement gel/unhydrated cement particle mixture and the surface of the filler; under the action of hydration reaction, base layer absorption and surface evaporation, the water is further reduced, and the emulsion is dehydrated again during the drying process, and the formed stacked layer gathers forming a film, bonding the hydration reaction products together to form a complete network structure, the composite system formed by cement hydration and latex powder film formation, the combined effect of which can improve the dynamic crack resistance of putty.
