What are the Main Components of Redispersible Powder



Redispersible powder, the full name is ٻيهر ورهائي سگهجي ٿو powder, the name directly corresponds to its descriptive characteristics. It is a kind of polymer emulsion powder after spray drying treatment, and has the ability to re disperse in aqueous solution to form emulsion .The main components of redispersible powder include the following aspects:

 

Redispersible Powder Contains Polymer Resin  

 

This is the core part of redispersible powder and the main component that plays its role. Polymer resins are usually prepared by copolymerization of monomers such as ethylene and vinyl acetate, such as ethylene/vinyl acetate copolymer (EVA), vinyl acetate and tertiary carbonate copolymer, etc. It can re disperse into emulsion after contacting with water, providing cohesive force and strengthening effect for mortar and other systems.

 

Redispersible Powder Contains Additives (Internal) 

 

These additives work together with the resin to modify the resin, such as plasticizers that lower the film-forming temperature of the resin. But not every type of rubber powder contains internal additives, which depends on the specific formula and performance requirements of the product.

 

Redispersible Powder Contains Protective Colloids  

 

A layer of hydrophilic material called protective colloid is wrapped around the surface of redispersible powder  particles. This layer of material mainly plays a role in protecting polymer powder particles from damage during storage and transportation, and promoting their redispersion when polymer powder comes into contact with water. The vast majority of protective colloids for ٻيهر ورهائي سگهجي ٿو powder are polyvinyl alcohol (PVA).

 

Redispersible Powder Contains Additives (External)  

 

To further expand the performance of redispersible powder, external additives are sometimes added. These additives can be selected according to specific needs, such as super water reducers used to improve flowability. However, not every redispersible powder contains external additives.

 

Redispersible Powder Contains Anti Caking Agents 

 

This is a fine mineral filler mainly used to prevent latex powder from clumping during storage and transportation, and to enhance the flowability of latex powder. Anti caking agents usually do not affect the performance of latex powder.

 

In summary, the main components of redispersible latex powder include polymer resin, additives (internal/external), protective colloids, and anti caking agents. These components work together to give redispersible latex powder excellent adhesion, flexibility, weather resistance, and redispersibility, making it widely used in fields such as construction, adhesives, etc.
