High-Performance VAE Redispersible Polymer Powder (RDP) for Modern Construction
InnoNew VAE Redispersible Polymer Powder (RDP), also known as VAE powder, is a spray-dried polymer designed for dry mix mortar applications. When mixed with water, it re-disperses into a stable emulsion, forming a flexible polymer film that enhances adhesion, cohesion, and durability.
Our VAE Redispersible Polymer powder (RDP) is widely used in tile adhesive, wall putty, self-leveling mortar, EIFS, and waterproof mortar systems. It provides excellent workability, water retention, and crack resistance, making it essential for modern construction formulations.

FAQ
Q1: What is VAE 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: How does Innonew RDP improve the performance of tile adhesives?
A: Our RDP optimizes the rheological properties of mortar, effectively extending the Open Time and enhancing Sag Resistance. This allows installers more time to adjust tiles and ensures that heavy, large-format tiles do not slip when applied to vertical surfaces.
Q3: Can you provide customized RDP grades?
A: Yes, we offer customized grades based on Tg, MFFT, and specific application needs.
Q4: Do you provide samples?
A: Yes, free samples are available for testing and evaluation.
Q5: How do RDP and HPMC work together in a formulation?
A: HPMC primarily provides water retention and thickening to ensure mortar doesn’t dry out too quickly during application, RDP provides the post-hardening strength and elasticity, this “Golden Combo” ensures both excellent workability for the contractor and superior physical properties for the final structure.
Q6: Do you provide other construction chemicals for tile adhesive?
A:Yes, In addition to Redispersible Polymer Powder (RDP/VAE), we supply:
- HPMC (Hydroxypropyl Methyl Cellulose)
- MHEC (Methyl Hydroxyethyl Cellulose)
- HEC (Hydroxyethyl Cellulose)
- PCE (Polycarboxylate Superplasticizer – powder & liquid)
- PVA (Polyvinyl Alcohol)
