What is Redispersible Polymer Powder?

RDP is a dry polymer powder that redisperses in water to form a flexible polymer solution, used to improve adhesion and flexibility in construction materials.

Celotech RDP-Vinabond® can prevent structural failure and enhance your construction materials longevity dramatically. As a versatile, spray-dried thermoplastic resin, Vinabond® upgrades mortar performance significantly to meet the demands of modern, sustainable building solutions.

Frequently Asked Questions

Is RDP Compatible With Other Additives?

Yes, RDP works well with:

Cellulose ethers
Starch ethers
Defoamers
Air-entraining agents
Retarders/accelerators

What's The Difference Between Different Rdp Grades?

Grades vary by:

Polymer composition
Glass transition temperature (Tg)
Minimum film-forming temperature (MFFT)
Particle size distribution
Redispersion characteristics

What is the Recommended Dosage of RDP?

Typically 2–5% of the dry mortar weight, depending on performance requirements.

What is the Role of RDP in Mortar？

RDP plays an important role in polymer-modified mortars nowadays. Because RDP can improve flexibility and crack resistance, increase adhesion, extend open time, increase cohesion and strength, improve workability and impermeability.

How Does RDP Work in Construction Materials?

When mixed with water, RDP redisperses into a film-forming polymer that enhances adhesion, flexibility and durability in cement-based products.

What Types of Polymers are Used in RDP?

Common polymer bases include:

Vinyl acetate-ethylene (VAE) – widely used due to good adhesion and flexibility
Styrene-acrylate(SA) – offers excellent water resistance and weatherability
Pure acrylics (Acrylic polymers) – used when superior UV and alkali resistance is needed
Usually: Vinyl acetate & Vinyl versatate (VeoVa) copolymers – sometimes used for enhanced hydrophobicity
