1. Raw material selection The first step in making redispersible polymer powders is selecting the appropriate raw materials. The main ingredients include polymer binders, protective colloids and additives. Polymer Binder: The choice of polymer binder is critical as it directly affects the properties of the final powder. Commonly used polymers include vinyl acetate-ethylene (VAE) copolymer, […]

Enhanced Adhesion and Bonding Strength redispersible polymer powders are engineered to enhance adhesion and bonding strength. By incorporating RDP into tile adhesives and cement plasters, users experience superior adhesion to surfaces, ensuring that the materials remain firmly in place and perform reliably over time. This enhancement is particularly valuable for projects requiring robust and lasting […]

The redisperside polymer powder is water-soluble redispersible powder, which is divided into ethylene/vinyl acetate copolymer, vinyl acetate/ethylene tert carbonate copolymer, acrylic acid copolymer, etc. The powder adhesive made after spray drying uses polyvinyl alcohol as protective colloid. This kind of powder can be quickly redispersed into lotion after contacting with water. Because redisperside polymer powder has high […]

Redispersible polymer powders (RDP) are commonly used in the construction industry as additives in cement-based mortar formulations. These polymers enhance the performance of mortar by improving properties such as adhesion, flexibility, water resistance, and workability. When formulating cement-based mortar with RDP, it’s essential to consider several factors to achieve the desired properties. Here are some […]

The main Redispersible polymer powders currently used in the market are: vinyl acetate vinegar and ethylene copolymer latex powder (VAe/E), ethylene and vinyl chloride and lauric acid ethylene vinegar ternary copolymer latex powder (E/VC/VL), vinyl acetate vinegar and Ethene and higher fatty acid vinyl ester ternary copolymer latex powder

The minimum film-forming temperature refers to the minimum temperature at which polymers form a continuous film, expressed by MFT. If the cement hydration temperature is below this value, the energy supplied will not be enough to start film formation.

The first step in the production of redispersible polymer powders is the production of polymer dispersions, also known as emulsions or latexes.  the water-emulsified monomers (stabilized by emulsifiers or macromolecular protective colloids) react with initiators to start emulsion polymerization.

The main Redispersible polymer powders currently used in the market are: vinyl acetate vinegar and ethylene copolymer latex powder (VAe/E), ethylene and vinyl chloride and lauric acid ethylene vinegar ternary copolymer latex powder (E/VC/VL), vinyl acetate vinegar and Ethene and higher fatty acid vinyl ester ternary copolymer latex powder (VAe/E/VeoVa), vinyl acetate vinegar and high fat acid vinyl vinegar copolymer latex powder (VAe/VeoVa), acrylic vinegar and styrene copolymer latex powder (A/S),
