Naphthalene Superplasticizer SNF/FDN/PNS Ready Mix Concrete Admixture
Product description:
CAS No.: 36290-04-7
HS Code: 38244010
All the names:
SNF is a high range water reducer, high concentrate naphthalene-based superplasticizer, also named
Naphthalene Sulfonate Formaldehyde Condensate (NSF), FDN, PNS, etc.
Brief introduction: SNF is high range water reducer, commonly referred to as a super plasticizer.
It is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation,
condensation and neutralization reaction and then drying to powder.
SNF possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength
enhancing. It has low alkali content, low sulfonate, and high purity. It can be widely used in different concretes
with less dosage and easy to use.
