REDISPERSIBLE POLYMER POWDERS (RPP)
Trade name: Neolith ®
Manufacturer: FAR SPA (Italy)
Redispersible polymer powders are the most common generic modifiers and binding components of the majority of dry mixes for different purposes.
Redispersible polymer powders (RPP) - a dry powder organic polymers which when mixed with water form aqueous dispersions. RPP, in combination with binders, which are hydrated, allow you to create ready-modified dry mixtures of stable quality, which needs only water to be added. The main property of RPP is their ability to rapid dispersion in water. This process occurs by mixing the dry mixture containing RPP, with water. As a result of processes of mortar setting and water binding, dispersed particles agglomerate and form a phase of the polymer film that can get in the final product the required general and specific properties depending on the purpose and application scope of the compositions - dry mixes.
Application of redispersible powders can significantly improve the basic performance of systems based on mineral binders (cement, sand, gypsum, etc.):
-
Adhesion to the substrate of various materials;
-
Elasticity (resistance to deformation and dynamic loads);
-
Tensile strength and flexural strength;
-
Water resistance, mechanical strength (for gypsum materials after interaction with moisture);
-
Reduction of water absorption and hydrophobization;
-
Resistance to abrasion;
-
Spreading and Leveling (for self-levelling flooring compounds);
-
Preservation of vapour permeability;
-
Frost resistance and durability (for facade systems)
-
Easy application and spreading;
-
Open time and workability.
