Brand Name : SULFADIOL^®-7Q (GS-7Q)

Usage : Reactive Dispersant agent for Water-based PUD Synthesis

       Or Reactive Emulsifier

SULFADIOL^®-7Q is a highly reactive dispersant agent for manufacturing water-based Polyurethane
Resin( PUD) has strong anti-hydrolysis and stability of storage than other types of dispersant agents. 
like DMPA and DM BA. And also, we researched and developed the application by ourselves technology.
SULFADIOL^®-7Q consists of sulfonated sodium salt and terminated Hydroxy group which is derived from
added 4 moles of propylene oxide. And it is a widely used chain extender in water-based polyurethane resin
syntheses like adhesives for woodwork or for shoes and artificial leather.

Molecular Structure :

1.     Characteristic

SULFADIOL^®-7Q is a good reactive dispersant for water-borne polyurethane dispersant(PUD) with strong hydrophilic property and also has a good compatibility with acidic or basic condition, then which can widely applicable with various reagent. It was developed as a product to replacement of DMBA, DMPA with carboxyl ionic center. So SULFADIOL^®-7Q has highly hydrophilic property and storage stability than DMPA, and also has low sensitivity to influence of external environment (temperature or pH). Furthermore, due to the SULFADIOL^®-7Q is a neutralized by sulfonated sodium salt type, which is no needed the neutralizer, allows a wider range of process variations in preparing the polyurethane dispersion.
