HSN-C is a high range water reducer, high concentrate naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.
Sodium Naphthalene Sulphonate Formaldehyde is made of naphthalene, sulforic acid, formalin and alkali, through sulphuration, hydrolyzation, condensation and neutralization reaction. HSN contains no chloride.
ASTM C 494, Type F; ASTM C 1017, GB8076-1997 and GB50119-2003.
Main Use & Advantages
1.HSN superplasticizer can be applied to make flowable, strong or steam-curing concrete. The minimum working temperature can be as low as 0 degree C. In steam curing, concrete with superplasticizer has to be strong enough before heating.
2.HSN 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.

Packing,Storage and Transportation
1.For powder: Woven fabric bag with plastic liner. Net weight: 25kg +/- 0.13 kg.
2.Cautions should be taken to prevent packages from being torn by sharp-ended objects while being transferred or delivered. When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
3.It should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective in one year. After the expiration date, it can be used again if testing results fall within the established range.
