JINT-502 RDP: The High-Performance Redispersible Polymer Powder for Advanced Building Materials

What is JINT-502 Redispersible Polymer Powder?

JINT-502 is a free-flowing, white powder obtained by spray-drying a Vinyl Acetate VeoVa copolymer dispersion. The "redispersible" property is key: when mixed with water, the powder particles readily re-form a stable polymer emulsion, distributing a flexible polymer network throughout the mortar matrix. This process, known as film formation, binds the cement particles and aggregates together, dramatically improving the mortar's characteristics compared to unmodified mixes.

Key Properties and Advantages

Integrating RDP JINT-502 into your dry-mix formulations delivers a host of technical benefits:

• Excellent Adhesion Strength: Provides strong bond strength to a variety of substrates, including concrete, brick, wood, and old tiles, reducing the risk of delamination.

• Enhanced Flexibility and Crack Resistance: The polymer film absorbs mechanical stress and accommodates minor substrate movements, preventing crack propagation and improving impact resistance.

• Superior Water Resistance: Offers improved resistance to water ingress and weathering, ensuring long-term durability in both interior and exterior applications (EN 12004).

• Improved Workability and Cohesion: Grants excellent sag resistance, open time, and smooth application, reducing slip in tile adhesives and improving the finish of renders.

• High Compatibility: Designed for optimal performance in alkaline environments with cement and other common dry-mix ingredients.

Primary Applications of JINT-502 RDP

This versatile polymer powder is a cornerstone additive for high-quality specialty mortars:

1. Tile Adhesives and Grouts: Enhances adhesion for ceramic, porcelain, and natural stone tiles. It ensures a flexible, water-resistant bond, crucial for areas exposed to moisture and temperature fluctuations.

2. External Thermal Insulation Composite Systems (ETICS): As a key component in basecoat and decorative finish renders, it improves cohesion, flexibility, and impact resistance, protecting the insulation layer.

3. Self-Leveling Underlayments (SLU): Promotes exceptional flow, leveling, and surface hardness while reducing cracking from shrinkage or substrate stress.

4. Repair and Skim Coat Mortars: Improves bonding to old concrete, flexibility, and durability for structural repair and surface renovation projects.

5. Waterproofing and Rendering Mortars: Increases elasticity, crack-bridging ability, and adhesion for thin-layer and decorative facade renders.
