Product Description

YL-SNF-A is a high range water reducer and high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc.

YL-SNF-A (Na2SO4≤5%) contains no chloride and is non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. Thus, it meets the requirement of chemical admixture specifications for concrete, complying with ASTM C 494, Type F. ASTM C 1017, GB8076-2008 and GB50119-2003 etc.

1.YL-SNF-A has no retarding and no air-introducing. It is characterized as good superplasticing performance, high water-reducing rate and high strength with low dosage. It has no chloride, low alkali content, low sulphonate and high purity. This product is easy to use and can be widely used in different concretes.

2.YL-SNF-A can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade degree. In steam curing, concrete with superplasticizer has to be strong enough before heating. The steam curing specification has to be pre-tested. It is particularly used as base material for compound admixtures.
