High Range Water Reducing Concrete Admixture

YL-PPM Polycarboxylate Superplasticizer (Powder for dry mix)

ASTM C494, Type F

 

Description

YL-PPM is a free flowing, spray dried powder of new generation poly-carboxylate polymer,

used as a superplasticizer for cement based materials. It is also an excellent dispersion plasticizer

suitable for gypsum, ceramic and other mineral materials.

 

Uses

� -Self-leveling

� -Structure grout

� -Cable grout

� -Repair mortar

� -Floor screed/thin-overlay

� -Cement coating/paint

� -Gypsum, ceramic products

� -Products containing silica fume, silica flour, pigment and other ultra-fine particles

� -Architectural products.

 

Advantage

Comparing to naphthalene and melamine based water reducers, YL-PPM Polycarboxylate

superplasticizer has superior characteristics of:

� -High-effective water reduction up to 30%

� -Excellent stability, providing long working time

� -Unique homogeneous plasticizing property, thus preventing segregation and bleeding

� -Good disperser for various types of cement and gypsum and minerals.
