As formulation demands for high-performance dry-mix mortars keep rising across global construction markets, many mortar manufacturers are hitting performance limits with conventional VAE redispersible polymer powder (RDP). To address complex outdoor, low-temperature, UV-resistant and high-water-resistance formulation requirements, Botai Chemical is expanding its VINNATE® RDP portfolio with three new polymer grades: Styrene-Acrylic (SA), Styrene-Butadiene (SBR) and Pure Acrylic RDP.
These new RDP products will be officially previewed at CHINACOAT 2026, the premier coating and construction chemicals exhibition in Asia. Our technical team welcomes formulators, R&D engineers and dry-mix mortar producers to discuss your toughest formulation challenges and custom polymer solutions.
What Are the New VINNATE® RDP Grades?
RDP, or redispersible polymer powder, is a core polymer additive for dry-mix mortars. When mixed with water, it re-emulsifies and forms a continuous polymer film inside cementitious systems, improving adhesion, flexibility, water resistance, crack resistance and weatherability. While VAE RDP remains widely used, advanced exterior and high-spec applications require specialized polymer chemistries.
VINNATE® Styrene-Acrylic (SA) RDP
VINNATE® SA RDP is engineered for superior water resistance, long-term weatherability and strong substrate adhesion.
- Core benefits: High water resistance, outstanding weatherability, stable bonding strength
- Typical applications: Exterior decorative mortars, high-performance tile adhesives If your finished mortars suffer from water ingress, surface chalking or bonding failure under outdoor exposure, SA RDP is an ideal upgrade for your exterior formulations.
VINNATE® Styrene-Butadiene (SBR) RDP
VINNATE® SBR RDP delivers excellent flexibility and reliable low-temperature performance, making it suitable for cold-climate construction systems.
- Core benefits: High flexibility, low-temperature toughness, good deformation resistance
- Typical applications: Cold-climate exterior mortars, flexible joint fillers, waterproofing mortar systems For projects in cold regions where thermal contraction and expansion cause cracking and debonding, SBR RDP improves the elasticity of cementitious matrices and reduces failure risks.
VINNATE® Pure Acrylic RDP
VINNATE® Pure Acrylic RDP features premium UV resistance, long-term durability and effective crack reduction.
- Core benefits: Excellent UV stability, long service life, crack control
- Typical applications: Tile adhesives, exterior wall putty, repair mortars, EIFS skim coats Pure acrylic chemistry minimizes ageing and colour fading under long sun exposure, which is critical for external insulation and finishing systems and exterior repair materials.
VINNATE® VAE RDP: The Trusted Benchmark for General Formulations
Alongside the three new RDP series, Botai’s mature VINNATE® VAE RDP range continues to serve a broad spectrum of dry-mix formulation needs. VAE RDP excels in boosting adhesion, flexibility, water repellency, self-leveling performance and extended open time for standard mortars, gypsum products and tile adhesives.
With the expanded portfolio, Botai Chemical can now provide one-stop RDP selection: from cost-effective VAE to high-end SA, SBR and pure acrylic grades, matching different climate zones, performance standards and budget requirements for your dry-mix mortar lines.
