RDP & HPMC are key raw material additives in construction.

Jan. 15, 2026

In the fast,paced construction industry,high quality additives are what make

building materials durable and easy to work with.

Redispersible Polymer Powder (RDP) and Hydroxypropyl Methylcellulose (HPMC)

are total must haves they boost the performance of dry mix mortar,plaster,tile adhesives etc.

If you're a construction professional looking to elevate your project quality,

getting to know RDP in construction and HPMC is essential.

① RDP in Construction: Boosts Strength and Flexibility

RDP is a core additive for modern building.

When mixed with water,it forms a continuous polymer film,

turning traditional cement-based materials into high-performance composites.

● Key Benefits of RDP : Especially for Tile adhesive(Mortar Tiling)

Advantage	What It Does
Strong adhesion	Bonds tiles and substrates tightly,no hollowing or detachment (even in harsh environments)
Better flexibility	Reduces material brittleness
Crack resistance	Prevents cracks by aiding proper cement hydration
Water retention	Keeps mortar from drying too fast

JTDF's RDP comes in EVA & acrylic formulations.

It's perfect for flexible tile adhesives,crack resistant plaster and self-leveling compounds.

Strict quality control ensures consistent,long lasting results.

② HPMC: Makes Materials Easier to Use

HPMC works great with RDP in construction.

It's a non ionic cellulose ether that improves cement based and gypsum based materials.

● Key Benefits of HPMC

Advantage	What It Does
Water retention	Stops mortar from drying quickly in harsh conditions,reducing cracks
Thickening	Improves material consistency
Lubrication	Makes mixing and applying materials easier
Extends open time	Lets you align tiles precisely (great for tile adhesives)

JTDF's HPMC fits dry-mix mortar, wall putty/plaster, tile adhesive, EIFS mortar etc.

We offer tailored viscosity grades to meet different project needs.

③ RDP + HPMC: Better Together

Using RDP and HPMC together solves key construction problems.

RDP boosts adhesion & flexibility,while HPMC improves water retention and workability.

Application	What the Blend Delivers
Wall putty/plaster	Smooth,crack resistant finish
Repair mortars	Stronger,more impact resistant,longer structure lifespan
General use	Faster construction,lower maintenance costs
