Textile / Leather Naphthalene Sulfonate Formaldehyde Sodium Salt
EINECS No 200-838-9
Naphthalene Sulfonate formaldehyde sodium salt produces concrete with extremely workable characteristics referred
to as high slump. PNS also allows concrete to be produced with very
low water/cement ratios at low or normal slumps.
Naphthalene Sulfonate formaldehyde sodium salt is ideal for use in prestress, precast, bridge deck or any concrete
where it is desired to keep the water/cement ratio to a minimum and
still achieve the degree of workability necessary to provide easy
placement and consolidation

Applications of naphthalene sulfonate formaldehyde sodium salt
1. Disperse dyes, reactive dyes, vat dyes dispersant, leveling
2. Pesticidedispersing agent, fillers, leather tanning agents,
3. Concrete water reducer, oil well cement water reducing agent.
4. In thepaper industry as slime control, reduce sides, improve
filler or fines retention, improved sizing,
5. lower paint viscosity.
6. Used for water-based paints, pigment pastes efficient
7. Paste used as a dispersing agent in acrylic series, Series C.
aldehyde, chlorine partial series of latex paint.
8. It can also be used as adhesives, powder filling and sealing
layer polymers to improve water resistance.
