Product Description
High Quality Naphthalene Superplasticizer Early Strength Concrete Additive for Bridge
Alternative name:
Sodium naphthalene sulfonate formaldehyde, SNF, sodium naphthalene sulphonate formaldehyde condensate, poly naphthalene sulphonate formaldehyde, PNS, FDN, superplasticizer,
high efficiency slushing agent.
Product description:
Sulphonated Naphthalene Formaldehyde Condensate is light yellow to yellow-brown powder, an anionic surfactant. sodium naphthalene sulfonate is soluble in water, acid, alkali and hard water, good dispersion properties. With protein and polyamide fibers have affinity. Mainly used to coloring for vat dyes, reactive dyes, acid dyes, acid staining pad or pigment pad dyeing of the dispersing agent, as a auxiliaries for vat dyes's powder or sizing agent. Also used staining to levelling agent and auxiliary tanning agent in leather industry.

Advantages
Low dosage 0.5~1.0% of cementitious material.
On the condition of slump unchanged, water reduction up to 12~20%.
Increase the slump10cm min, when keep the water-cement ratio no change.
Good slump retention ability improve durability of the concrete.
Improve durability of the concrete.
Increases the concrete strength.
No corrosion to the steel-bar.
Application:
Naphthalene superplasticizer early strength increases the early strength of the concrete, has no effect on the late strength or slightly increases, and can be compounded with a high-efficiency water reducing agent, and the reinforcing effect is more remarkable.

Dosage:0.5 - 1.5% by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
SNF-C can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing (better). The after-mixing approach can achieve better result.
Packing&Delivery:For powder: Woven plastic bag with film liner. Net weight: 25kg +/- 0.2 kg.
It should be stored in a dedicated warehouse that is well-ventilated and dry and keep
away from moisture.
Shelf Life: Minimum 12 months. After the expiration date, it can be used if testing results is qualified.
