Hecocell®6628 Re-dispersible polymer powder can be dispersed in water and re-emulsified to form a stable emulsion. in addition to reaching the superior performance of EVA emulsion, it provides excellent convenience and reliability in the storage and transportation, because of the very high content of Ethylene in EVA emulsion as the raw material of this product, the glass transition temperature canreach-2℃ below, so the product has excellent softness feature.
Hecocell®6628 Re-dispersible polymer powder when used with cement, gypsum and other inorganic cementitious materials together can enhance the adhesion strength between mortar and ordinary support between the adhesive force, improve cohesive strength and workability of mortar and greatly improve the tensile strength of materials and anti- Bending degree.
Hecocell®6628 Re-dispersible polymer powder superior performance:
·Enhance the adhesive property and mechanical strength of mortar;
·Reduce the elastic modulus of mortar improve cohesion, increase the wear resistance of mortar;
·Give the mortar with good heat resistance, water resistance, freeze-thaw resistance and aging resistance;
·Increase the flexibility of the mortar reduce or avoid cracking of cement mortar etc;
·Effectively reduce the bibulous rate of mortar.
Applications:
þThermal insulation(EPS,XPS)mortar þPlaster mortar(anti-crack) þWaterproof mortar
þHeat preservation system þExterior flexible putty þFlexible thin layer of mortar
þWear-resisting flooring þConcrete repair þ Plastering anhydrite
þBinding mortar þ Interface agent caulking compounds interior and exterior wall coating, etc.
Storage:
It should be stored in a cool.dry place, and we suggest that it should be used up once for all after opening the bag, so as not to be affected by moisture;
Its useful life is 6months and it should be used as early as possible under high temperature and wet conditions to avoid increasing agglomeration probability;
Because of the thermoplastic city of the powder, the sacked height of the product is not allowed exceeding one tray.
