Project Description

RDP for putty powder

Properties and applications of redispersible polymer latex powder

Redispersible polymer emulsion powder is easy to be re-dispersed in water and/or alkaline cement mortar. Its performance is basically the same as that of the parent polymer emulsion, which is the prerequisite for its application. Moreover, it has good storage stability. Under conventional storage conditions, the polymer powder does not adhere to each other and maintains good fluidity. Typical properties of our redispersible polymer latex powder products are shown below.

Application of redispersible polymer latex powder in building putty

  • (1) It can avoid the difference of the established application performance of the product, and water can be added in proportion during construction;

  • (2) It can reduce packaging and transportation costs (save water transportation), and reduce packaging treatment costs;

  • (3) With good freezing-thawing stability, no need to consider microbial erosion;

  • (4) no volatile organic matter, reduce pollution, has a unique environmental advantage.

Redispersible polymer latex powder and cement and other inorganic cement materials used together, can be used to improve the comprehensive performance of building putty (especially the external wall waterproof putty), polymer cement mortar, especially compressive strength, bonding strength with other substrate, water resistance and construction performance.

Advantages of RDP

  • (1) redispersible polymer emulsion powder has good uniformity and stable performance. It is a kind of latex powder with great practical value. It is widely used in the modification of building putty and cement mortar. It is used to improve the compressive strength of building putty, cement mortar, bonding strength with other substrates, water resistance and constructability.

  • (2) the high performance, single component solid building putty developed by the redispersible polymer emulsion powder is not cracked, and has good flexibility and water resistance. It has good adhesion performance with the substrate, which can ensure the long-term decorative effect of the coating. Moreover, the production process is simple, and the transportation is convenient, so it has a broad market prospect.

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.
●This product is non-toxic, non-irritating and non-flammable.

Storage life: 12 months from production date. If the shelf life exceeds, it must be tested and verified before use.

Packaging and transportation

It is sealed with polypropylene woven bag lined with polyethylene inner bag, net weight of each bag is 25kg.Avoid rain and sun during transportation.
