Dispersible Polymer Powders - Binding ability and water resistance

It is well-known that polymer-modified mortar, cement and concrete have significantly better properties that their unmodified counterparts. Manufacturers add the polymers either as a dispersion (two-component systems) or as a powder (one-component systems).

During the production of gypsum mortar, concrete or mineral cementitious materials such as cement, polymer powders which are dispersible are added to the mixing water and subsequently undergo redispersion.

Redispersible polymer powders can increase a material's bending tensile strength, abrasion resistance and compressive strength because the polymer modification decreases the water content in cement. The reduced water absorption caused by the polymer dispersion also makes mortar and cement more resistant to freeze-thaw cycles.

On top of that, when added to a material, redispersible polymer powders are able to maximize adhesive tensile strength, enhance elasticity and reduce porosity.

As a trusted supplier of specialty chemicals, we are able to help you find the right additive and raw materials to optimize your construction materials.

In addition to cement and gypsum mortar, dispersible polymer powders can be used to improve the properties of sealants, caulk, fillers, wallpaper adhesives, tile adhesives and exterior wall coatings.

Redispersible polymer powders are able to significantly enhance a material's processability. Adding the powders before hydration will not only decrease the amount of water required for processing, but also simplify handling and extend the amount of time you can work with the material.

After curing, the material in question will have a better bond to the substrate as well as greater flexibility. The cohesion between various construction components will also be stronger - even without the addition of plasticizers.

Redispersible polymer powders can give tile adhesives excellent adhesion, even allowing them to create a strong bond to difficult substrates such as natural stone, wood and plastic.
