Vinyl Acetate-Ethylene (VAE) Redispersible Polymer Powder – Premium VAE RDP Manufacturer & Supplier China
InnoNew® Vinyl Acetate–Ethylene (VAE) Redispersible Polymer Powder is a high-performance, free-flowing powder obtained by spray-drying VAE emulsion. Designed for dry-mix mortar formulations, it readily redisperses in water to form a stable polymer dispersion, providing excellent adhesion, flexibility, and mechanical strength.
This product significantly enhances the performance of cement- and gypsum-based systems by improving workability, water retention, and resistance to cracking. It also delivers superior bonding strength to various substrates, including concrete, masonry, and insulation boards. InnoNew® VAE powder is widely used in tile adhesives, wall putty, self-leveling compounds, repair mortars, and EIFS/ETICS systems.

FAQ
Q1: What is Redispersible polymer powder (RDP)?
A: RDP is a spray-dried polymer powder that re-disperses in water to form a film, improving adhesion and flexibility in construction materials.
Q2: What is the difference between RDP and latex powder?
A: RDP is a dry powder that re-disperses in water, offering better storage stability and easier handling compared to liquid latex.
Q3: Can you provide customized RDP grades?
A: Yes, we offer customized grades based on Tg, MFFT, and specific application needs.
