Sodium Naphthalene Sulfonate Formaldehyde (SNF/PNS/NSF/FND)
Sodium naphthalene sulfonate (SNF) is a light yellow to yellow-brown powder, and it is easily soluble in water, ethylene glycol, diethylene glycol, slightly soluble in alcohols, and insoluble in organic solvents. In construction industry, sodium naphthalene sulphonate is widely used to prepare free-flowing and pumpable concrete mixtures.
Influence of Condensed Silica Fume on the Rheology of Cement Paste
These pastes were added 1.32% of the super-plasticizers SSP and SNF by mass of powder either with the mix water or delayed (D), and the flow curves were selected from the 2 nd cycle (test interval 5).

Sulphonated Naphthalene Formaldehyde (SNF) - Kingsun Chemicals
Sulphonated naphthalene formaldehyde, also known as naphthalene superplasticizer or SNF superplasticizer, is a high-range water reducing admixture for concrete. It has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability.
- What is sodium naphthalene sulfonate formaldehyde (SNF/PNS/FND?
- Sodium naphthalene sulfonate formaldehyde (SNF/PNS/FND/NSF), also called naphthalene sulfonate formaldehyde condensate, poly naphthalene sulfonate,sulphonated naphthalene formaldehyde,SNF superplasticizer, is commonly referred to as a superplasticizer for concrete. It is the light brown powder in appearance.
- How to use Sulphonated naphthalene formaldehyde superplasticizer?
- Use SNF powder directly, or add it after the cement aggregate is fully moistened with 60% mixing water. The sulphonated naphthalene formaldehyde superplasticizer has good adaptability with other concrete chemical admixtures.
- What is sodium naphthalene sulfonate water reducing admixture?
- Sodium naphthalene sulfonate can improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete. Naphthalene formaldehyde sulfonate water reducing admixture has good adaptability to various cements and good compatibility with other types of concrete admixtures.
- What is poly naphthalene sulfonate?
- Poly Naphthalene Sulfonate (PNS)has a significant enhancement effect on concrete, and its strength can be increased by 20%-60%. Sodium naphthalene sulfonate can improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.
- Who makes Sulphonated naphthalene sulphonate formaldehyde (SNF)?
- As a leading manufacturer & exporter of sodium naphthalene sulfonate formaldehyde (SNF) in China, Kingsun company has been focusing on the research and production of sulphonated naphthalene formaldehyde for many years.
- How to make powdery sodium naphthalene sulfonate?
- The preparation of powdery sodium naphthalene sulfonate requires a series of processes, such as sulfonation, hydrolysis, condensation, neutralization, filtration, and spray drying, etc. The production of SNF superplasticizer is mature and its performance is stable.
