Redispersible Polymer Powder (RDP) is a polymer used in a variety of applications. RDP is a water-soluble powder made from a variety of polymers, including vinyl acetate, vinyl acetate ethylene, and acrylic resins. The powder is mixed with water and other additives to form a slurry, which is then applied to different substrates. There are several types of RDP, each with its own unique properties and uses. In this article, we’ll explore some of the most common types of RDP and their applications.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers are the most common type of RDP. They are made from vinyl acetate and vinyl acetate ethylene copolymer. The polymer particles are dispersed in water and can be reconstituted into a liquid state. This type of RDP has a wide range of applications including dry mix mortars, cement products and self leveling compounds. They offer excellent adhesion, flexibility and durability.
2. Acrylic redispersible polymer
Acrylic redispersible polymers are made from acrylic or methacrylic copolymers. Their exceptional strength and abrasion resistance make them ideal for applications where durability is critical. They are used in tile adhesives, exterior insulation and finishing systems (EIFS), and repair mortars.
3. Ethylene-vinyl acetate redispersible polymer
Ethylene-vinyl acetate redispersible polymers are made from ethylene-vinyl acetate copolymers. They are used in a variety of applications including cement mortars, grouts and tile adhesives. They have excellent flexibility and adhesion for use in high stress environments.
4. Styrene-butadiene redispersible polymer
Styrene-butadiene redispersible polymers are made from styrene-butadiene copolymers. They are used in a variety of applications including concrete repair mortars, tile adhesives and grouts. They have excellent water resistance and adhesive properties.
5. Re-emulsifiable polymer powder
Re-emulsifiable polymer powder is an RDP designed to be re-emulsified in water after drying. It is used in many applications where the product is exposed to water or moisture after use. These include tile adhesives, grout, and caulk. They have excellent water resistance and flexibility.
6. Hydrophobic redispersible polymer powder
Hydrophobic redispersible polymer powders designed to increase the water resistance of cement-based products. It is typically used in applications where the product will come into contact with water, such as Exterior Insulation and Finishing Systems (EIFS), swimming pool tile adhesives and concrete repair mortars. It has excellent water resistance and durability.
Redispersible latex powder is a versatile material that can be used in many applications. There are several types of RDP, each with its own unique properties and uses. Their excellent adhesion, flexibility and durability make them ideal for use in a wide variety of products. When used correctly, they can help improve the quality and longevity of many building products.
