Redispersible Polymer Powders (RPP)

Trade name: Neolith®

Manufacturer: FAR SPA (Italy)

Redispersible polymer powders are the most common universal modifiers and mandatory components of most dry building mixtures for various purposes.

Redispersible polymer powders (PPPs) are dry powders of organic polymers that, when mixed with water, form aqueous dispersions. RPP in combination with binder materials that are hydrated make it possible to create ready-made modified dry mixtures of stable quality, to which only water can be added. The main property of PPPs is their ability to quickly disperse in water. This process occurs when a dry mixture containing PPP is mixed with water. As a result of the processes of solidification of the solution and the binding of water, the dispersed particles agglomerate and form a phase of polymer film, which allows obtaining in the final product the necessary general and special properties depending on the purpose and field of application of the compositions — dry building mixtures.

Application

The use of redispersed powders can significantly improve the main indicators of systems based on mineral binders (cement, sand, gypsum, etc.):

• Adhesion to bases of different materials;
• Elasticity (resistance to deformation and dynamic loads);
• Tensile and bending strength;
• Water resistance, mechanical strength (for gypsum materials after interaction with moisture);
• Hydrophobization and reduction of water absorption;
• Resistance to abrasion;
• Spreading (for levelers);
• Preservation of vapor permeability;
• Frost resistance and durability (for facade systems)
• Ease of application and ease of use;
• Processing time and processing ability.

Pricing information and orders.RPP Neolith P manufactured by F.A.R. S.P.A. can be ordered in the volume from 1 kg to 21 tons (machine standard) from the company “Chemcontinent”. Direct deliveries are possible from warehouses in Kiev (Ukraine) and Filago (Italy).

‍

Packaging and transportation.RPP is supplied in multilayer paper bags of 25 kg. It is possible to deliver in big bags of 500 kg in accordance with the wishes of the customer.

‍

Storage of redispersed polymer powders.Store at a temperature of 5 to 30ºС. Pallets with bags or big bags should be stored, arranged in one tier to avoid caking the powder. The shelf life of PPP is 6 months from the date of production.
