Product Name: Redispersible Polymer Powder, VAE, RDP.
CAS No.: 24937-78-8
Main Components: polymer resin.
Function: Re-dispersible latex powder is made of ethylene – vinyl acetate copolymer, after spray drying modified emulsion powder, it has good re-dispersibility, and water contact with the re-dispersed into an emulsion, and with its chemical properties and the initial emulsion is exactly the same, and the evaporation of water can be formed after the film, the film has a high degree of flexibility, high weathering and high adhesion to a variety of substrates. In addition, the hydrophobic latex powder can make the mortar has good waterproof property.
Applications: Construction grade applications (external wall insulation; wall putty; gypsum-based series; dry-mix mortar; tile adhesive, etc.), coatings.
Shengda Support Service: We can provide customised product service according to regional, climatic and other different factors. Departures to Indonesia, Thailand, Pakistan, Brazil, South Africa and many other countries to provide on-site technical support.

Redispersible Polymer Powder Application

The polymer film formed by Shengda Dispersible Latex Powder has excellent flexibility and significantly improves the flexural and bending strength of the mortar. This film is formed on the surface and in the interstices of the mortar particles, creating a filmic connection that gives the hard mortar more elastic properties. As a result, this technology significantly enhances the bond strength and adhesion of the mortar. As an organic binder, our re-dispersible polymer powders are able to form thin films with high tensile and adhesion strengths on a variety of substrates, thus improving the impact resistance, durability and abrasion resistance of mortars.

As the interstices of the mortar are filled with the powder particles, the density of the mortar is increased, which in turn improves its abrasion resistance. The application of our RDP products also enhances the weathering, freeze-thaw and crack resistance of the final product. As thermoplastic resins, our products exhibit excellent flexibility, allowing the mortar to adapt to hot and cold changes in the environment, thereby preventing cracking due to temperature changes.

Our dispersible latex powder products are widely used in various fields, including tile adhesives, exterior wall insulation systems, tile caulking, wall putty, self-leveling flooring mortar, interface mortar, cementitious waterproofing mortar, repair mortar, masonry plaster mortar and other types of construction materials, as well as EPS plastering and decorative materials. Our products show excellent performance in these applications and provide reliable solutions for all kinds of construction and decoration projects.

Summary of Frequently Asked Questions

Redispersible Polymer Powder (RDP) is a finely textured, free-flowing white powder. Upon contact with water, this polymer powder quickly redisperses into individual particles without altering its inherent properties. The applications for redispersible polymer powders are diverse. Tailoring our approach to specific applications allows our team to enhance product properties, such as water retention and anti-sagging, ensuring optimal performance for various needs.

RDP finds its application in the formulation of building materials, encompassing tile adhesives, grouts, finishing plaster, smoothing compounds, repair mortars, and sealing pastes. Shengda RDP is primarily employed within the construction industry.

We use bags of 25 kg to pack our products.

If pack HPMC and RDP with Ton bags and you have your own formula, we can mix them for you.
