FAQ
Q1: How does RDP improve Tile Adhesive performance?
A: RDP increases bonding strength, improves open time, enhances flexibility, and reduces cracking or tile slipping.
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.
Q4: Do you provide samples?
A: Yes, free samples are available for testing and evaluation.
Q5: What is Redispersible Emulsion Powder (RDP/VAE) used for?
A: RDP is a spray-dried polymer powder that redisperses in water to form a stable emulsion. It is widely used in tile adhesives, wall putty, self-leveling mortars, EIFS systems, and cement-based repair mortars to improve adhesion, flexibility, water retention, and crack resistance.
Q6: What is the difference between RDP and PVA powder in construction application?
A: RDP (Vinyl Acetate–Ethylene) provides higher flexibility, water retention, and adhesion in cement-based mortars, while PVA powder mainly enhances adhesion and film formation. In many formulations, they can be combined for synergistic effects, but the ratio must be optimized.
Q7: 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)
