Dry-mix Mortar Admixture Redispersible Powder (RDP)
Product Description
RDP for Thermal Insulation Material 
Redispersible powder is widely used in exterior wall insulation and finishing systems for its convenience in storage and transportation and reliability in construction. Function of RDP 
1. RDP in bonding layer
In order to improve the equilibrium stability of binder quality, the screened liquid polymer was firstly prepared into
redispersible emulsion powder. When it is made in the factory with cement, sand and other additives after dry mortar mixed with water at the scene, to disperse into the original eaux, play with the emulsion polymer in the same film and enhancement effect,because of its unique design, not 2 times under the influence of water dispersion in mortar hardened, binder usually contains more than 3% can be dispersed emulsion powder again can achieve good bonding effect.
2. RDP in protective layer mortar
The protective layer plays a key role in the long-term stability and mechanical stability of the system. As with bonded layer mortar, this layer is modified with a polymer containing ethylene redispersible latex powder. In addition, to increase crack resistance and durability, the bonded layer is embedded with a polymer-coated alkali resistant mesh cloth.
3. RDP in finishing layer
As the protective layer is still a cement base, all most common finishes are available. Considering the structural characteristics
of the protective layer, the surface coating is required to have a good match in terms of elastic modulus, water resistance and
air permeability, so it is necessary to add dry mixed surface mortar with re-dispersible powder. Quality standard
Use and storage ●Avoid direct contact with eyes and skin during use. Protective gloves and goggles are recommended. In case of accidental exposure, please clean the stained part with clean water.
●The product should be well protected from moisture during storage. If affected by moisture, the product is easy to agglomerate.
