Product Description
CAS Code: 36290-04-7
HS Code (CN):38244010
SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene SulphonateFormaldehyde Condensate (short name: SNF, PNS, NSF, etc ...)SNF is made firom naphthalene. sulfuric acid. formaldehyde and liquid alkali. through sulfonation. hydrolvzation.condensation and neutralization reaction and then drying to powder. SNF-10% contains very small chloride. Thus, itmeets the requirements of chemical admixture specifications for concrete. ASTM Designation C 494 as a Type Fadmixture.

Packing and Storage
1. Normaly packed in 25kg woven bags with inner plastic lining. Customized package may be available if required.
2. Kept in dry and ventilating place, prevent from rain and moisture when storageif agglomerated, please crush and make it into solution, and its effect will be the same.
3. Non-toxic, harmless, non-inflammable and non-explosive chemicalsit can be transported in truck and train.
Application
1. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.
2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
3. Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
