HPMC and RDP Additives for Dry Mortar
HPMC cellulose ether and RDP redispersible polymer powder for tile adhesive, wall putty, waterproof mortar and self-leveling mortar formulation support.
What HPMC and RDP Do
- HPMC improves water retention, workability, open time and anti-sag performance.
- RDP improves bonding strength, flexibility, water resistance and polymer modification.
- The final grade selection depends on cement, filler, local sand, climate and application method.
Typical Applications
These additives are commonly used in tile adhesive, wall putty, plaster mortar, waterproof mortar, repair mortar and self-leveling mortar. NEO can discuss additives together with dry mortar plant configuration so the equipment and formula direction match the target product.
FAQ: HPMC and RDP Selection
How do I choose HPMC?
Start from viscosity, water retention, open time, construction temperature and the target product such as tile adhesive, putty or plaster.
How do I choose RDP?
RDP is selected by bonding strength, flexibility, water resistance and compatibility with cement and local fillers.
Can NEO recommend dosage?
Yes. Send the base formula, local raw materials and target performance. NEO can suggest an initial dosage range for lab trial mix.
Send your target product, current formula and test requirements. We can suggest HPMC/RDP grade direction, TDS/MSDS and trial mix notes.
