Customer Case: RDP Redispersible Polymer Powder in Construction Applications
Redispersible Polymer Powder (RDP) is a key construction polymer additive used in dry mix mortar systems such as tile adhesives, wall putty, repair mortars, and external insulation systems. In recent years, demand for RDP for dry mix mortar has increased rapidly as contractors look for better bonding strength, flexibility, and long-term durability.
One of our overseas customers is a mid-sized building materials manufacturer focusing on tile adhesive RDP formulations for residential and commercial projects. Their main challenge was ensuring stable bonding strength while maintaining easy workability under different weather conditions.
Project Challenges
Before using our Redispersible Polymer Powder (RDP), the customer faced several common problems:
Tile adhesives showed insufficient bonding strength on low-absorption tiles
Mortar layers were too brittle, leading to cracking after curing
Poor flexibility caused detachment under temperature changes
Inconsistent performance between different production batches
These issues directly affected customer satisfaction and increased after-sales complaints.
RDP Solution and Application
After testing several formulations, the customer decided to introduce our RDP cement mortar solution into their tile adhesive system.
Once mixed with water, the RDP for dry mix mortar redispersed evenly and formed a flexible polymer film during curing. This film significantly improved adhesion between tiles and substrates while increasing overall flexibility.
Key improvements observed on-site:
Stronger tile bonding, even on porcelain and large-format tiles
Better flexibility, reducing cracks and hollow sounds
Smoother workability and easier troweling
Stable performance in both hot and humid environments
Project Results
After switching to our construction polymer additive, the customer reported clear improvements:
Tile detachment issues were almost completely eliminated
On-site application became faster and more consistent
Customer complaints dropped significantly
Product reputation improved in local markets
Customer feedback:
“This RDP solved our tile bonding and cracking problems. The performance is stable and easy to control.”
