REDISPERSIBLE POLYMER POWDER is a free-flowing, white powder obtained by spray drying of an aqueous vinyl acetate-ethylene copolymer dispersion. When blended with water, these powders redisperse back into liquid emulsions with essentially identical properties to the original emulsions.
- Construction: Redispersible polymer powders are most commonly used in the construction industry. They are added to cement-based products, such as mortars, tile adhesives, grouts, self-leveling compounds, exterior insulation and finish systems (EIFS), and concrete repair materials.
- Coatings and Paints: They are also used in the formulation of paints and coatings, particularly in exterior paints and textured coatings.
- Pharmaceuticals: In the pharmaceutical industry, redispersible polymer powders may be used as a matrix in tablet formulations.
- Agriculture: In agriculture, they can be used in crop protection products and as carriers for agricultural chemicals.
- Other Industries: RPPs have applications in various other industries, such as textiles, adhesives, and sealants.
Safety : Redispersible polymer powder (RPP) is generally safe to handle when proper precautions are taken. To minimize exposure, inhalation, and contact, wear appropriate personal protective equipment (PPE) , such as goggles, gloves, and lab coats. Use respiratory protection, ventilation, and avoid dust generation. Wash hands and skin thoroughly after handling the powder, avoid eating, drinking, or smoking in handling areas, store the powder in a dry area, and be familiar with emergency contact information for poison control and medical assistance. Dispose of empty containers and excess product in accordance with local regulations, avoiding environmental contamination.
