Detailed Introduction

YL-PPM-聚羧酸高效减水剂

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.
