What is Redispersible Polymer Powder RDP? Core Properties & Terminology

Redispersible polymer powder RDP consists of specialized polymers (primarily VAE - Vinyl Acetate-Ethylene) spray-dried to ultra-fine, free-dispersing particles. Upon mixing with water, it redisperses to form a flexible, strong polymer film, mimicking original emulsion properties.

RDP VAE: Vinyl Acetate-Ethylene based redispersible powder; offers optimal flexibility and bond strength for mortars and adhesives.
Redispersible Polymer Powder: Engineering polymer that reconstitutes in water; enables modification of dry-mix mortars.
Redispersible Acrylic Polymer Powder: Acrylic polymers for enhanced UV resistance and weatherability.
RDP Powder Uses: Construction adhesives, cement renders, self-leveling compounds, wall putty, crack repair, insulation boards (EIFS).

The unique performance relates to copolymer composition, particle engineering, and advanced spray drying, ensuring excellent flow, storage stability, and rapid redispersion, all certified under ISO 9001:2015, EN 12004, and relevant ANSI standards (ISO 9001, EN 12004).

FAQ: Redispersible Polymer Powder RDP — Key Technical Questions

Q1: What are the main raw materials in redispersible polymer powder rdp?

A: The primary ingredient is Vinyl Acetate-Ethylene (VAE) copolymer or Acrylic copolymer. Additives include polyvinyl alcohol (PVA), cellulose ether (for film formation and stability), and anti-caking agents.

Q2: What technical parameters determine RDP’s performance?

A: Solid content, particle size (80–120μm), glass transition temperature (Tg, -8°C to +15°C), redispersibility index, minimum film forming temperature (MFFT), and residual monomer content are key. Particle engineering controls adhesive strength, flexibility, and water resistance.

Q3: Which international standards do redispersible polymer powder rdp products comply with?

A: ISO 9001:2015, ISO 13320 (particle size testing), EN 12004 (tile adhesives), EN 13813 (floor screeds), ASTM C557 (dry wall adhesives), and optionally FDA, REACH or RoHS.

Q4: What is the shelf life and recommended storage conditions?

A: Typical shelf life is 18–24 months in dry, cool (<30°C, RH<60%) environments, original packaging. Avoid humidity, direct sun, and contact with oxidizers.

Q5: How can I optimize dosage for different cement mortars?

A: Standard RDP dosing: 1.5–3.5% by weight for cement mortars, up to 6% for flexible adhesives and EIFS. Higher grade RDP VAE/AC copolymers may allow lower dosages with superior performance.

Q6: Can redispersible polymer powder rdp be used in potable water or food-safe systems?
