Sulfonated Naphthalene Formaldehydes (SNF) Superplasticizer

Features and Applications :

CAS Code: 36290-04-7
HS Code (CN): 38244010 

Concrete admixture SNF superplasticizer price concrete chemicals sodium naphthalene sulfonate formaldehyde is a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etc…)


Concrete admixture SNF superplasticizer price concrete chemicals SNF superplasticizer powder water reducer sodium naphthalene sulfonate formaldehyde is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation C 494 as a Type F admixture, GB8076-2008 and GB50119-2003.

Performance :

Visual Appearance: Light brown powder. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 10-30% when it is mixed with reinforced concrete at 0.3-1.5%.
Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased.
