RDP

Redispersible Polymer Powder

Redispersible Polymer Powder (RDP)

Redispersible Polymer Powder (RDP) is spray dried redispersible emulsion powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and  react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity. Redispersible Polymer Powder RDP improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.

Features

The products can be dispersed in water,improve the adhesion between mortar and common support;with high compressive strength with early strength,it can improve mechanical properties of mortar and enhance the work-ability of mortar

PRODUCT SAFETY

According to the national laws and records on hazardous substances,RDP is not a hazardous substance.For further safety information,see its Material Safety Data Sheet.

STORAGE AND TRANSPORTATION

Latex powder is a hygroscopic and water-absorbing polymer powder,and its storage and transportation process should be in the original packaging,and keep it cool and dry.During production and use,once the original packaging is opened,resealing measures must be taken to avoid moisture intrusion.

SHELF LIFE

In a cool,dry place for at least six months.For products beyond the shelf life,a verification test should be carried out to determine.
