VAE Redispersible Polymer Powder Manufacturing
ZHIWEI (Jinan) New Materials Co., Ltd. has manufactured VAE-based redispersible polymer powder since 2020. Our RDP is produced from VAE emulsion with PVA protective colloid through controlled spray drying, with product grades designed for different dry-mix mortar performance requirements. Eight RDP grades cover tile adhesive, wall putty, EIFS/ETICS, self-leveling compounds, waterproof mortar, repair mortar and other polymer-modified cementitious systems. Application testing supports grade selection and batch consistency before commercial shipment.
- Neutral, enhanced, hydrophobic, thixotropic and leveling series
- Application R&D lab tests every lot in real mortar
