Redispersible Polymer Powder (RDP Chemical)
If you are looking for more details, kindly visit our website.
RDP powder, i.e Redispersible Polymer Powder, is a water soluble polymer made from ethylene-vinyl acetate (EVA) polymer through spray drying, it's designed for the construction industry to enhance the properties of dry mortar blends.
RDP powder is always combined with cellulose ethers and other additives to improve the properties and performance for the cement based or gypsum based mortar, such as better water-retention,open time,better work-ability, increasing adhesion to a variety of substrate and higher flexural strength and flexibility etc..
Its technical ability to increase the cohesiveness, flexibility, bond strength and most importantly the water proofing property, form a film with high tensile strength and bonding strength on different substrates.

As a leading RDP Powder manufacturer and supplier, we would like to share further information you need on RDP powder. If you have any questions on Redispersible Polymer Powder chemical powder or wanna get free quotation of Redispersible Polymer Powder, please feel free contact us at any time.
Redispersible Polymer Powder (RDP)
Redispersible Polymer Powder (RDP) is redispersible latex powders, based on vinyl ethylene acetate emulsion,which are divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., powder bonded after spray drying It uses polyvinyl alcohol as a protective colloid. This kind of powder can be quickly redispersed into emulsion after contact with water, because the redispersible latex powder has high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc.
Characteristics
Redispersible Polymer Powder (RDP) has outstanding bonding strength, improves the flexibility of the mortar and has a longer open time, imparts excellent alkali resistance to the mortar, and improves the adhesiveness, flexural strength, water resistance, plasticity, and abrasion resistance of the mortar. In addition to workability, it has stronger flexibility in the flexible anti-cracking mortar.

Advantages
1.RDP does not need to be stored and transported together with water, reducing transport costs;
2.Long storage period, anti-freezing, easy to keep;
3.The packaging is small in size, light in weight and easy to use;
4.RDP can be mixed with hydraulic binder to form a synthetic resin modified premix. It only needs to add water when using it. This not only avoids errors in the mixing on the site, but also improves the safety of product handling.
Key Properties:
RDP can improve adhesion, flexural strength in bending, abrasion resistance, deformability. It has good rheology and water retention, and can increase the sag resistance of tile adhesives, it can made up to tile adhesives with excellent non-slump properties and putty with good properties.
Packing:
Packed in multi-ply paper bags with polyethylene inner layer, containing25 kgs; palletized & shrink wrapped.
20&#;FCL load 14ton with pallets
20&#;FCL load 20 ton without pallets
Storage:
It should be stored in a cool and dry place. The recommended period of use is six months. Please use it as early as possible when using it in summer. If it is stored in a hot and humid place, it will increase the chance of agglomeration. Please use it once as much as possible after opening the bag. Finished, otherwise you need to seal the bag to avoid absorbing moisture from the air.
Safety notes:
The above data is in accordance with our knowledge, but don&#;t absolve the clients carefully checking it all immediately on receipt. To avoid the different formulation and different raw materials, please do more testing before using it.
