RDP VEOVA/VA

Vinyl Acetate-Vinyl Versatate (VEOVA/VA) Polymers

JTBON® VEOVA/VA Polymer Powder is made from VAcE and VEOVA via spray drying. Due to the bulky alkyl groups in VeoVa, it shows strong steric hindrance, low polarity, and excellent hydrophobicity. Its stable molecular structure ensures outstanding alkali and hydrolysis resistance, while the higher Tg provides greater rigidity and bonding strength than conventional EVA.

Key Advantages

Superior Alkali Resistance

The long α-alkyl side chains create significant steric hindrance, stabilizing the ester groups and enhancing resistance to alkaline degradation and hydrolysis.
Effective Water-Reduction and Water-Retention

It improves the workability of cement mortar by reducing water usage and maintaining adequate moisture.
Air-Entrainment

The powder contributes to an entrained air structure, enhancing freeze–thaw durability and overall performance in harsh conditions.
Optimized Strength Balance

It lowers the compressive to flexural strength ratio to below 3, ensuring a more balanced and robust mechanical profile.
Reduced Shrinkage

Incorporation of the powder minimizes shrinkage, decreasing the likelihood of cracks and enhancing long-term stability.
Enhanced Water Impermeability

It improves the water resistance and anti-penetration capability of cement mortar, extending structural durability.

Q&A

Q1: Can RDP be used in dry-mix mortar?

A: Yes, RDP is specifically designed for dry-mix mortar. It improves adhesion, flexibility, and workability while ensuring long-term durability. When mixed with water on-site, it redistributes effectively, enhancing mortar performance.
Q2: Can RDP be used in exterior applications?

A: Yes, RDP is widely used in exterior applications such as EIFS, waterproofing mortars, and etc. It enhances weather resistance, flexibility, and adhesion, making it ideal for outdoor environments exposed to temperature changes and moisture.
Q3: What is the typical dosage of RDP in construction applications?

A: The dosage of RDP varies depending on the application, typically ranging from 1% to 5% of the total dry mix weight. We have TDS suggestion for each different RDP, ask now!
Q4: What are some best practices for handling and storing RDP?

A: RDP should be stored in a cool, dry place in its original sealed packaging to prevent moisture absorption. Avoid direct exposure to sunlight and high humidity. Use within the recommended shelf life for optimal performance.
