RDP Redispersible Polymer Powder​ Construction Admixture in Building Materials

RDP- Re-Dispersible Polymer Powders increase the adhesive strength between mortar and common support and improve the mortar’s mechanical performance.
In the polymer cement mortar, this RDP can increase the materials anti-bending and anti-tension properties.Therefore,this RDP has excellent anti-crack performance, which can prevent the materials from cracking effectively.

RDP Redispersible Polymer Powder in Building Materials

PTMA-RDP- Redispersible Latex Powder is a water-soluble redispersible powder, which is a polymer of ethylene/polyvinyl acetate/tert-carbonate, suitable for outdoor bonding, dry-mix mortar such as wall putty, tile glue, plaster mortar, etc..


The main component of the chemical group of redispersible polymer powder is (VAC/E) vinyl acetate/ethylene copolymer

Specification
Appearance : white powder
Particle size : 100 mesh (98%) passed
Solid content (%) : 99±1%
Bulk density (g/l) : 450~600
Ash (burning% at 1000℃) : 10±2%
PH value : 6-8
Minimum film formation ℃ : 0℃
Glass transition temperature Tg℃:  10±3℃

Re-dispersible latex powder, due to the adjustment of the main chain of the product (vinyl acetate/ethylene), the amount of ethylene inserted is appropriately reduced, the glass transition temperature of the polymer is increased, the rigidity is increased, and the cohesive strength is also increased. In the case that the film is strong and not losing flexibility, it can not only meet the requirements of polymer cement for bonding strength, but also meet the requirements for flexural strength.

The redispersible latex powder has better adhesion and adhesion, which can better improve the adhesion strength, cohesion, flexural resistance, wear resistance and workability of the mortar.

Application

♦ EPS, XPS thermal insulation bonding mortar

♦ Thin plastering mortar

♦ Floor mortar

♦ Tiles and various adhesives

♦ Wall Putty



Package : net weight 25kg (±1%)
Storage : 6 Months, if the shelf life is exceeded, but no caking phenomenon can still continue to use
Precautions : After opening, the unused rubber powder must be sealed to avoid moisture from air contact.
